NDHCE collaboration practice questions
14 original questions from the DHPrep starter set, with the correct answer and a rationale for every option. 4 of them use a shared case profile.
Collaboration is a scored domain with real weight, about 11–17% of scored items on the blueprint DHPrep uses. The free set gives it 14 questions, split evenly: seven with the person receiving care and the people who support them, and seven with other professionals.
Four of the fourteen use a shared case profile, so the consent and the roles in that profile are part of the question. The recurring miss is treating a signature, a family preference, or a colleague’s convenience as a transfer of the decision.
How to work this set. For each item, answer three questions before you choose: who is capable of this decision today, who else has information you need, and what you are allowed to share. Keep all three. Options that solve only one of them are the distractors.

Question 1
An 82-year-old client attends with an adult daughter. The client has mild cognitive impairment, can clearly describe today's preferences, and consistently chooses shorter appointments. The daughter objects to the client's worn partial denture and manages transportation and medications. The daughter produces a representation agreement giving her authority for personal care decisions. Which approach best applies person- and family-centred care in this situation?
- A. Follow the daughter's preferences for today's care because she holds authority for personal care decisions, and her agreement covers the chairside choices.
- B. Plan solely from the client's stated preferences and set the daughter's concerns aside.
- C. Support the client's current capable wishes, involve both perspectives, and make clear that decisions will be revisited as circumstances change.Correct answer
- D. Ask the daughter to leave so the client can decide freely without family influence.
Answer
C. Support the client's current capable wishes, involve both perspectives, and make clear that decisions will be revisited as circumstances change.
Support the client's current capable wishes, involve both perspectives, and make clear that decisions will be revisited as circumstances change (C).
Rationale
Person-centred care starts with the person's own values and current capable wishes; family-centred care adds the people who support them, without transferring the decision to whoever holds the most authority on paper. In Canada, an adult who is capable for a decision makes that decision, and substitute decision-making frameworks apply when the person is incapable for that decision; the details vary by province and territory, so the hygienist works with the client's documented capacity and the applicable local framework. Here the client can state preferences clearly today, so the worn partial denture and appointment length are decisions the client can make; the daughter's concerns are still relevant because they may reflect comfort, function or safety observations the client has not mentioned, and because she is part of the support system. Excluding the daughter would remove both a source of information and the practical support that makes these visits possible. The hygienist's role is to bring the perspectives together, document the discussion, and keep reviewing choices rather than treating the representation agreement as a switch that silences the client, or the client's current wishes as a reason to ignore the family.
Why each option lands where it does
- A. A representation agreement supports decision-making when a client is not capable for a particular decision. Treating it as a present override regardless of the client's expressible wishes removes the client from the decision and is not person-centred.
- B. Setting the daughter aside protects the client's stated preferences but discards information and support the plan depends on. Family-centred practice invites the support network to contribute while the client's capable wishes direct the plan.
- C (correct). This approach keeps the client at the centre, uses the capable wishes as the guide, gathers the daughter's observations, and builds in periodic review. It also avoids making an irreversible choice about either the denture or the care relationship.
- D. Asking the daughter to leave is not required to obtain the client's own view and may undermine the visit, since the client may rely on her for decisions, transport and daily support. Influence and support are not the same as coercion.
Decision rule. When family preferences and a client's current capable wishes differ, keep the client central but keep the family involved; apply substitute decision-making only for decisions the client cannot make, and check the local framework.
Takeaway. A capable client's current wishes direct the plan; family members contribute information and support, and decisions are revisited, not fixed.
Common miss. That a signed representation agreement removes the client from decisions the client can still make.
Question 2
A client with a history of treated periodontitis declines the bitewing radiographs recommended at today's continuing-care visit, saying, "I do not want any more radiation this year." The clinical examination is unremarkable today, and the client understands that imaging helps detect changes between visits. Which response best promotes the client's autonomy while protecting their care?
- A. Repeat the recommendation with the clinic's standard explanation until the client agrees.
- B. Accept the decision, explain its effect on today's assessment, document the discussion, and state when revisiting it would help.Correct answer
- C. Record that the client refused recommended care and tell them that the clinic may not be able to continue managing their periodontal condition.
- D. Take a panoramic radiograph instead, since it is a single exposure and may substitute for the bitewings.
Answer
B. Accept the decision, explain its effect on today's assessment, document the discussion, and state when revisiting it would help.
Accept the decision, explain its effect on today's assessment, document the discussion, and state when revisiting it would help (B).
Rationale
Promoting autonomy and self-determination means supporting a capable client's informed decision, including a decision to decline a recommended service. The hygienist has already provided the information that makes the decline informed: the client understands what imaging adds. Repeating the recommendation until agreement is pressure, not persuasion, and it undermines the trust that keeps clients returning. Threatening an end to care for a single declined recommendation overstates the consequences and punishes the decision. Substituting a panoramic image makes a different exposure decision for the client rather than with them, and it may not answer the question the bitewings were meant to answer. The proportionate response documents what was declined, why, and what the client understood, then sets out how and when the assessment can proceed without images and when the decision merits revisiting, such as if new signs appear or a specific question arises. If the client wants to reconsider later, the record supports that; if they never do, the clinician has done what the framework requires.
Why each option lands where it does
- A. Repeating a recommendation the client has already considered and declined shifts the purpose of the conversation from informing to overcoming resistance, which is inconsistent with informed choice.
- B (correct). This response respects the decision, keeps the client informed about the limits it creates, records the discussion for continuity and gives a concrete future point to revisit it without pressure.
- C. A single declined recommendation is not grounds to end a care relationship, and framing it that way coerces the decision by exaggerating the consequence.
- D. Changing to another imaging modality does not resolve the client's stated concern about radiation and makes an additional exposure decision without their agreement.
Decision rule. When a capable client declines a recommended service, confirm their understanding, accept the decision, record it with the reasoning, explain how care proceeds without it, and note when revisiting would be appropriate.
Takeaway. Informed refusal is a valid decision: document it, explain the limits it creates, and leave a clear point to revisit it.
Common miss. That accepting a decline means abandoning the recommendation, or that declining must be overridden for the client's own good.
Question 3
Partway through a visit, the hygienist realises she documented an examination finding on the wrong tooth. The client has noticed nothing. Which action best builds a relationship based on trust, integrity and respect?
- A. Disclose the error now, correct the record accurately, and confirm the finding is rechecked.Correct answer
- B. Correct the record quietly, since the client was not affected and mentioning it would only cause worry.
- C. Wait until the next visit and mention it then, when there is more time to explain.
- D. Leave the original entry and add a note that the finding is probably on the adjacent tooth instead.
Answer
A. Disclose the error now, correct the record accurately, and confirm the finding is rechecked.
Disclose the error now, correct the record accurately, and confirm the finding is rechecked (A).
Rationale
Trust is built in exactly these moments: information is corrected openly while the client can still see it happen, and the record ends accurate. Telling the client now — briefly, plainly, without drama — shows that her chart belongs to her and that mistakes are owned rather than managed. Rechecking the finding gives the disclosure a clinical purpose beyond confession, because the point of the error is the finding it mislabeled. Quiet correction protects the clinician's comfort and leaves the client unaware that anyone treats records loosely; delayed disclosure turns a small moment into a kept secret; and preserving a known-wrong entry while hedging it compounds the original error with a second one.
Why each option lands where it does
- A (correct). Immediate, simply-worded disclosure with accurate correction and rechecking respects the client and keeps the record truthful.
- B. Silent correction avoids momentary awkwardness at the cost of the transparency the relationship depends on.
- C. Postponing disclosure serves the schedule, not the client, and time does not make an unexplained error easier to trust.
- D. Adding a contradictory note leaves the record internally inconsistent and nobody certain which entry is true.
Decision rule. When you discover a documentation or clinical error, tell the client in plain language, correct the record accurately, and take the clinical step that confirms the correct finding.
Takeaway. Trust grows when errors are disclosed early, corrected plainly and shown to change the care.
Common miss. That an unnoticed error can be managed quietly without touching the trust the relationship stands on.
Question 4
A dental hygiene clinic wants recall visits to run more smoothly. Which approach best reflects sharing knowledge, resources and responsibilities with others?
- A. Keep all client education and scheduling tasks with the hygienist, so the message stays consistent.
- B. Ask the receptionist to teach clients how to use interdental brushes, since she has time between calls.
- C. Assign each responsibility to the role that can properly carry it and review the arrangement.Correct answer
- D. Send the team a long email describing everything that should change and let everyone interpret it in their own role.
Answer
C. Assign each responsibility to the role that can properly carry it and review the arrangement.
Assign each responsibility to the role that can properly carry it and review the arrangement (C).
Rationale
Sharing responsibility works when each share matches what the person is trained and authorized to do. Clinical assessment and health education stay with the hygienist; prepared information and appointment logistics suit the receptionist; set-up and supply tasks belong with the assistant within its scope. Agreeing on this division in conversation, not by decree, gives each team member a clear part and a way to raise problems, and the review step turns the arrangement into something the team improves. Concentrating everything with the hygienist defeats the purpose of a team. Assigning clinical teaching to the receptionist puts an instructional task in a role that is not responsible for it, whatever the available time. A broad email asks everyone to guess at their part, which is how responsibility dissolves instead of being shared.
Why each option lands where it does
- A. Holding every task keeps the hygienist as a bottleneck and denies the team the roles that could handle logistics and support.
- B. Available time does not create clinical accountability; teaching technique belongs where clinical responsibility sits.
- C (correct). Role-matched responsibilities, agreed together and reviewed, put each task where competence and scope live.
- D. An unassigned message leaves everyone interpreting for themselves, which is allocation in name only.
Decision rule. When dividing clinic work, assign each responsibility to a team member whose role and scope cover it, confirm the arrangement with the team, and re-evaluate it periodically.
Takeaway. Share responsibilities by matching each task to the role that is accountable for it — then review together.
Common miss. That sharing work means moving tasks to whoever is free rather than to whoever is accountable.
Question 5
An older client with early cognitive changes lives with her son, who helps manage her daily routine. She has consented to sharing care information with him. Which approach best reflects collaborating with her support network?
- A. Address all communication to the son, since he manages her daily life and best understands the household, so nothing gets lost.
- B. Keep the son informed informally but record nothing, so the record stays focused on the client.
- C. Include client and son with her agreement, confirm what is shared, learn the home routine, and support the plan together.Correct answer
- D. Ask the son to decide on treatment approaches, since the client may not recall the discussions later.
Answer
C. Include client and son with her agreement, confirm what is shared, learn the home routine, and support the plan together.
Include client and son with her agreement, confirm what is shared, learn the home routine, and support the plan together (C).
Rationale
A support network strengthens care when the client stays at its centre. She has consented to sharing, but consent is not a transfer of the relationship: her preferences, her understanding and her role in the plan remain first. Including both in planning lets the son contribute what he uniquely knows — how routines happen in the household, what reminders work — while the client hears and shapes what is proposed for her. Documenting the involvement keeps the record honest about decisions and who participated. Addressing the son alone sidelines the person receiving care. Informal undocumented arrangements hide who was involved when the plan is reviewed. Asking the son to decide discounts her current capacity and starts a slide toward others deciding for her.
Why each option lands where it does
- A. Routing all communication through the son treats him as the client and reduces her to the subject of decisions.
- B. Unofficial information sharing blurs responsibility and loses the record of who agreed to what.
- C (correct). Client-led inclusion of the support person in planning uses his practical knowledge while preserving her authority.
- D. Handing decisions to the son presumes incapacity and removes a client who continues to understand and consent.
Decision rule. When a support person is involved, confirm the client's consent and preferences first, include both in planning, and record the client's decisions and who participated.
Takeaway. Collaborate with support networks through the client — her consent, her preferences, her plan, with everyone's role documented.
Common miss. That consent to share information transfers decision-making to the support person.
Collaborate with oral health professionals and others

Question 6
During periodontal maintenance, a dental hygienist identifies two molars with deep probing depths, suppuration and increased mobility, while the client's radiographs from last year show bone loss at those sites. The dentist owns the diagnosis of the restorative and surgical needs, and a periodontist works two blocks away. Which action best addresses this client's needs through collaboration with the other professionals?
- A. Continue maintenance as planned and mention the sites at the client's next routine examination.
- B. Advise the client to book with the periodontist directly and take the radiographs if they have copies, since the periodontist will want to see them.
- C. Ask the receptionist to pass a message to the dentist about the sites without clinical details.
- D. Document and share the findings with the dentist and, with consent, coordinate a referral that carries the necessary clinical information.Correct answer
Answer
D. Document and share the findings with the dentist and, with consent, coordinate a referral that carries the necessary clinical information.
Document and share the findings with the dentist and, with consent, coordinate a referral that carries the necessary clinical information (D).
Rationale
Working together to address clients' needs means getting the right information to the right professional at the right time and keeping the client involved in the decision. The findings — deep pockets with suppuration and increasing mobility at sites with documented bone loss — indicate that this client's periodontal status has moved beyond what maintenance alone will resolve, so the hygienist's role is to raise it now, not at the next routine visit. A referral that simply tells the client to book leaves the periodontist without the context needed, may duplicate tests and can lose time. Passing an uninformative message through a third party has the same problem in a different direction. The coordinated route documents the findings, informs the dentist who holds related diagnostic responsibilities, involves the client's consent for sharing the record, and sends a referral that states what has already been done and what question needs answering. The client decides whether to attend; the hygienist's responsibility is to make the pathway clear and the information complete.
Why each option lands where it does
- A. Deferring to the next routine examination delays assessment of an active problem and assumes the finding will still be in a stable phase by then.
- B. Directing the client to the periodontist can be appropriate, but without information transfer the specialist starts from scratch and the dentist who diagnoses is bypassed.
- C. A message without clinical detail cannot support a treatment decision; the dentist will have to repeat the assessment or ask for the record anyway.
- D (correct). This path documents the change, informs the dentist, respects the client's consent for information sharing, and equips the periodontist with the history, findings, images and prior care needed to answer the referral question.
Decision rule. When findings require another professional's scope, document them, inform the relevant clinician, obtain consent for sharing, and send a referral that states the history, findings, images and care already provided.
Takeaway. Collaboration means transferring complete, consented information to the professional who can act, while keeping the client in the decision.
Common miss. That telling the client to see a specialist is the same as coordinating care.
Question 7
A client with mobility challenges repeatedly misses appointments because the only available times conflict with the accessible transit schedule in her area. Which action best promotes teamwork and partnerships to address the situation?
- A. Book her into the next available appointment and remind her of the importance of attendance.
- B. End the recall schedule until she arranges her own transportation reliably.
- C. Coordinate with the scheduling team around the transit windows and book times that work with the client.Correct answer
- D. Give her the phone number for the transit service so she can adjust her schedule to the appointment times.
Answer
C. Coordinate with the scheduling team around the transit windows and book times that work with the client.
Coordinate with the scheduling team around the transit windows and book times that work with the client (C).
Rationale
Promoting teamwork and partnerships means treating access as a shared problem rather than the client's fault. The reception team controls the appointment grid and knows its flexibilities; the hygienist knows the clinical recall interval and its importance. Bringing those two together around the transit schedule is how the partnership actually changes the outcome, and involving the client keeps the solution grounded in the real times she can travel. Reminding her about attendance repeats the problem without touching the cause. Pausing recall penalises her for a system mismatch and interrupts care the team is responsible for delivering. Handing over a transit phone number pushes the coordination work back onto the person the system already failed.
Why each option lands where it does
- A. Another reminder about attendance does nothing about the time conflict that causes the missed visits.
- B. Stopping recall because the schedule does not fit abandons the client's care over a fixable logistics problem.
- C (correct). Coordinating scheduling flexibilities with the client's transit windows makes the team, not the client, absorb the complexity.
- D. Passing the transit number along leaves the client to renegotiate the appointment system alone, which is what already failed.
Decision rule. When logistics block care, coordinate the relevant roles around the client's actual circumstances rather than repeating reminders or shifting the effort to the client.
Takeaway. Access problems are team problems: bring scheduling, clinical needs and the client's real constraints into one conversation.
Common miss. That missed appointments are primarily a client motivation issue.
Question 8
A colleague uses a sharpening technique that the hygienist believes is ineffective for the instruments they share. Which response best maintains a mutually supportive working relationship?
- A. Discuss the technique directly, compare instrument handling together, and agree on what shared instruments must pass.Correct answer
- B. Report the colleague to the practice manager so the technique is corrected officially.
- C. Continue using the instruments without comment, since the colleague has more experience.
- D. Hide the shared instruments and use a personal set instead, to avoid future disagreements and keep the peace on the team.
Answer
A. Discuss the technique directly, compare instrument handling together, and agree on what shared instruments must pass.
Discuss the technique directly, compare instrument handling together, and agree on what shared instruments must pass (A).
Rationale
Mutually supportive relationships solve technical questions through direct, evidence-oriented conversation rather than through escalation, silence or avoidance. Bringing the concern to the colleague honours them as a professional who can engage with it, and comparing the instruments' handling — for example, whether they grip and cut properly — turns an opinion clash into a shared observation. An agreed test for shared instruments leaves the team with a standard stronger than either person's preference. Going to the manager first frames a solvable question as a disciplinary matter and makes future conversations harder. Using questionable instruments to keep the peace risks the treatment outcome, and hiding them shifts the problem rather than addressing it — both undermine the relationship in a different way.
Why each option lands where it does
- A (correct). Direct discussion plus a shared, objective check resolves the technical question and keeps the working relationship intact.
- B. Escalating before speaking to the colleague treats a professional question as a complaint and damages trust without examining the technique.
- C. Silence protects harmony at the expense of instrument performance and lets a fixable problem continue.
- D. Avoidance resolves nothing, leaves the disagreement unspoken and quietly withdraws shared resources colleagues expect to use.
Decision rule. For disagreements about shared technique or instruments, discuss directly with the colleague, use an objective check as the arbiter, and agree on a standing criterion.
Takeaway. Disagreements between colleagues are best resolved face to face with something observable to discuss — then agree on a standard you both trust.
Common miss. That keeping the peace means staying quiet about professional concerns.
Question 9
A client's updated history shows a newly prescribed blood-thinning medication, and subgingival instrumentation is planned for today. Which action best consults with others in this situation?
- A. Proceed with the planned instrumentation and observe how much bleeding occurs during treatment.
- B. Cancel today's care and ask the client to contact the clinic when the medication is reviewed again.
- C. Confirm the implications with the prescriber, adjust the plan, and document the consultation.Correct answer
- D. Ask the client to decide alone whether treatment should go ahead despite the medication.
Answer
C. Confirm the implications with the prescriber, adjust the plan, and document the consultation.
Confirm the implications with the prescriber, adjust the plan accordingly, and document the consultation (C).
Rationale
Consulting others is how clinical uncertainty gets resolved with the people who hold the missing information. The prescriber knows why the medication was started, how it interacts with planned treatment and whether any modification is appropriate. Confirming those implications before instrumentation allows the visit to proceed under an informed plan — perhaps unchanged, perhaps adjusted — rather than being cancelled by default. Proceeding to watch how bleeding unfolds makes the client the experiment. Ending care indefinitely puts the burden of reconnecting on the client and rarely resumes smoothly. Asking him to make a risk decision he lacks the information to make hands him a professional judgement. The consultation keeps responsibility with the professionals involved while keeping care alive.
Why each option lands where it does
- A. Treating the appointment as a bleeding observation converts uncertainty into a risk taken with the client rather than resolved with his prescriber.
- B. Cancelling care and waiting for the client to return later abandons the plan over a question a phone call could answer.
- C (correct). Prescriber confirmation plus plan adjustment and documentation resolves the uncertainty and safely keeps care moving.
- D. The client cannot weigh bleeding-risk trade-offs he has no information about; that judgement belongs with the clinical team.
Decision rule. Consult the appropriate professional whenever a medical factor complicates planned treatment, adjust the plan from the response, and document the exchange.
Takeaway. When a medical change affects planned care, consult the prescriber, act on the answer, and record it — do not proceed on a gamble or abandon the plan.
Common miss. That the safest response to medication uncertainty is always to postpone care.
Question 10
A colleague regularly skips a step in the clinic's documented instrument-handling policy because it takes extra time. Which response best encourages them to apply the policy?
- A. Report the deviation to the manager immediately so the clinic is protected.
- B. Speak with the colleague directly, connect the step to its safety reason, and tackle the time pressure together.Correct answer
- C. Say nothing, since the step is only a small part of the full policy.
- D. Post the policy on the staff room wall so everyone sees it without a conversation, and a visible reminder usually works.
Answer
B. Speak with the colleague directly, connect the step to its safety reason, and tackle the time pressure together.
Speak with the colleague directly, connect the step to its safety reason, and tackle the time pressure together (B).
Rationale
Encouraging others to apply policies works through conversation that treats them as colleagues and the policy as shared ground. Naming the requirement and the reason behind it restores the why that rushed routines lose, and offering to address the time pressure together removes the incentive that produced the shortcut. Reporting first turns a fixable habit into a disciplinary matter and rarely changes practice. Saying nothing accepts a client-safety gap because it seems small, when the policy exists precisely to standardize steps that individuals underestimate. A wall poster adds visibility but not understanding, conversation, or a plan for the workload problem that caused the deviation.
Why each option lands where it does
- A. Escalation before dialogue treats a shared policy problem as individual misconduct and gives the colleague no path to change.
- B (correct). Direct, respectful conversation with the safety rationale and a joint fix addresses both the deviation and its cause.
- C. Silence about a known safeguard gap leaves clients exposed and quietly teaches that the policy is optional.
- D. Visual reminders change nothing about time pressure or understanding and cannot substitute for speaking with the person.
Decision rule. When a colleague bypasses a policy, talk directly, restore the documented rationale, and work on the practical cause before escalating.
Takeaway. Encourage policy application by connecting the step to its purpose and solving the pressure that pushed it aside.
Common miss. That either silence or escalation is the only alternative to watching a policy being skipped.
Case-based questions
Each profile below is shared with questions that test other domains. This page reprints the profile and only the questions tagged to this domain. The rest of that profile is on the domain page for each other question.
Case profile 1
Ms. Rowan Delisle is a 71-year-old retired postal clerk who moved into an assisted-living residence three months ago after her spouse's death. She manages her own affairs and describes her preferences clearly. Her medical history includes type 2 diabetes (metformin; most recent HbA1c 7.1%), hypertension (lisinopril) and hypercholesterolemia (atorvastatin). She reports dry mouth and has no known allergies. Her maxillary removable partial denture replaces teeth 24, 25 and 26. Assessment recorded generalized 3 to 4 mm probing depths with bleeding on probing in the posterior sextants, 2 mm recession at the mandibular anterior teeth, light to moderate calculus, and restorations with no visible recurrent caries. Hand osteoarthritis limits her grip; she brushes once daily and uses no interdental aids. Residence staff can provide reminders and transportation to appointments is available weekly. Ms. Delisle has a fixed pension and asks about costs; her daughter lives two hours away and calls weekly. Six weeks after initial periodontal therapy, reassessment shows reduced bleeding with residual 5 mm sites at teeth 16 and 17, and she reports that her mouth feels fresher.
Question 11
The residence care coordinator telephones to ask for details of Ms. Delisle's oral health so staff can support her daily mouth care. Ms. Delisle previously signed a consent allowing the residence care team to receive the information needed to support daily mouth care. Which action is best?
- A. Share only what the care team needs for daily mouth care under the existing consent, and document the disclosure.Correct answer
- B. Provide the complete chart, including medical history and billing records, because the coordinator is a health professional.
- C. Decline to discuss any information because oral health records are confidential.
- D. Ask Ms. Delisle to sign a new consent form before any information is provided to the residence.
Answer
A. Share only what the care team needs for daily mouth care under the existing consent, and document the disclosure.
Share only what the care team needs for daily mouth care, as authorized by the existing consent, and document the disclosure (A).
Rationale
Sharing client information with others must be consistent with informed consent and applicable privacy requirements. Ms. Delisle has authorized the residence care team to receive the information needed to support daily mouth care, so the task is to match the disclosure to that purpose: findings the staff must work with, such as areas needing gentler cleaning, the dry mouth, and the denture's fit issues, and practical instructions for them. A general request from a health professional does not convert consent into access to the whole chart, and billing details are unrelated to the purpose. Refusing outright is not required when a valid consent exists, and it would leave staff without the guidance they need to support the client's daily care, which is the very purpose the client agreed to. Requiring a new signature for every request is likely to delay care and is not needed when the existing consent covers the purpose, though consent should be revisited if the purpose changes. Recording what was disclosed keeps the record complete and supports accountability if the client later asks what was shared, which is itself part of respecting her autonomy.
Why each option lands where it does
- A (correct). Limited disclosure tied to the documented purpose respects the client's consent, gives the care team what it needs, and produces a record of what was shared and why.
- B. Being a health professional does not remove the requirement to limit disclosure to what the consent covers. Medical history and billing records are not needed to support daily mouth care, and sharing them exceeds the client's authorization.
- C. Refusing all disclosure ignores the client's signed consent and undermines the daily mouth-care support she agreed to receive. Confidentiality is protected by disclosing appropriately, not by withholding information the client authorized.
- D. A fresh consent is unnecessary while the existing one covers this purpose, and treating every request as requiring a new signature can delay the support the client depends on. Re-confirm consent if the request or purpose changes.
Decision rule. For a request about a client's information, identify the purpose, check the consent you have, share the minimum that satisfies the purpose, and document the disclosure.
Takeaway. Disclose only what the documented consent and the stated purpose require, and record what you shared.
Common miss. That a health professional's request authorizes release of the full record.
Question 12
Ms. Delisle says the interdental brushes recommended for her home care cost more than she can spend regularly from her fixed pension. Which action best assists her in accessing the resources she needs?
- A. Review her coverage and supply options with her, connect her with the appropriate contact, and document the referral.Correct answer
- B. Give her a clinic sample and tell her to ask the clinic again when it runs out.
- C. Suggest that she ask her daughter to purchase the supplies.
- D. Remove interdental cleaning from her care plan until her financial situation improves, since she cannot buy what she cannot afford.
Answer
A. Review her coverage and supply options with her, connect her with the appropriate contact, and document the referral.
Review her coverage and supply options with her, connect her with the appropriate contact, and document the referral (A).
Rationale
Assisting people in accessing community resources means working with the client to find routes that exist, not improvising a substitute. Ms. Delisle's barrier is financial and predictable: she has a fixed pension, lives in a residence that already orders supplies and supports its residents, and a local community dental program has been active in the region. Reviewing what those routes cover, and connecting her to the right person with a documented referral, gives her an ongoing solution she controls. A one-time sample defers the problem and depends on the clinic's goodwill rather than her access. Redirecting her to her daughter makes a family member responsible for a health service cost without knowing whether that is appropriate or welcome, and it may discourage the client from raising barriers in future. Dropping interdental cleaning because of cost removes an intervention that the clinical findings support in a client with residual pockets and dry mouth; the difficulty should be solved on the access side, not by withdrawing care. If no route covers the supplies, that finding is itself useful: it is grounds for the hygienist to pursue program-level options, which is a separate, longer-term advocacy step.
Why each option lands where it does
- A (correct). This option works with the client to identify real coverage and supply routes, links her to a contact and records the referral so follow-up is possible. It addresses the barrier without changing the clinical plan or shifting the burden to a third party.
- B. A clinic sample can bridge a gap once, but it does not create regular access and it makes the client depend on the clinic's stock and goodwill rather than on a durable arrangement.
- C. Asking the daughter assumes family capacity and willingness that have not been established and reframes a service cost as a private family obligation rather than an access issue.
- D. Withdrawing interdental cleaning removes a prevention measure the findings support. Cost is an access problem to be navigated, not a reason to reduce the client's plan.
Decision rule. When a client cannot afford an indicated aid, explore coverage and community routes with them and refer; change the clinical plan only for clinical reasons.
Takeaway. Treat cost barriers as access problems: connect the client to real resources and document the referral, rather than substituting gifts or removing indicated care.
Common miss. That a free sample or a family payment solves an ongoing affordability barrier.
Case profile 2
Ms. Priya Chandran is a 41-year-old elementary school teacher who recently returned to Canada after caring for her parents abroad. She takes sertraline for depression and reports persistent oral dryness, a burning tongue and sensitivity to cold. Her medical history is otherwise unremarkable and she has no known allergies. Her mother sometimes attends appointments and helps with language support, and the household follows a vegetarian diet with frequent small meals and sweetened tea through the day. Ms. Chandran has not received dental hygiene care for four years and is unsure what to expect.
Question 13
Which approach best applies a person-centred approach to Ms. Chandran's care when her mother attends the appointment?
- A. Direct explanations to her mother, since the family makes decisions together and her mother can explain things afterward.
- B. Ask her mother to wait in the reception area so the conversation stays strictly between clinician and client.
- C. Ask Ms. Chandran how she would like her mother involved and whether she wants help with language during the visit, then follow her direction.Correct answer
- D. Treat all clients the same way by following one standard script regardless of who attends with them.
Answer
C. Ask Ms. Chandran how she would like her mother involved and whether she wants help with language during the visit, then follow her direction.
Ask Ms. Chandran how she wants her mother involved and follow her direction (C).
Rationale
Person-centred care means the client defines the care relationship, including who participates. Ms. Chandran's mother may be a genuine support, but only Ms. Chandran can decide whether translation help, shared decisions or private conversations fit her wishes. Asking directly and following her answer respects both her autonomy and the practical role her family plays. Speaking to her mother as the primary recipient assumes a family decision model the client has not chosen and can leave the client out of her own care. Excluding her mother pre-emptively discards support the client may want and may undermine trust. A single standard script ignores the circumstances that person-centred care exists to notice.
Why each option lands where it does
- A. Treating the mother as the audience presumes a decision structure for the client and can bypass the person whose consent and preferences matter.
- B. Removing a supporter without being asked disregards a resource the client may value and can make the visit harder for her.
- C (correct). Asking the client how involvement and language support should work keeps control with her while using family support on her terms.
- D. A uniform script ignores individual preferences and support needs, which is the opposite of adapting care to the person.
Decision rule. When family members attend, ask the client how she wants them involved and follow that direction, including for language support and decision participation.
Takeaway. Let the client set the terms of family involvement and language support; the team adapts to the person, not the other way around.
Common miss. That involving family automatically makes care family-centred, regardless of the client's wishes.
Case profile 3
Mr. Daniel Osei is a 58-year-old long-haul truck driver who visits town twice a month. He takes lisinopril and amlodipine for hypertension, reports occasional heartburn, and his most recent blood pressure reading was 152/94. He drinks two to three colas during overnight drives and has limited access to fresh food on the road. His last dental visit was two years ago. He prefers to be shown things rather than read them, and he keeps a soft toothbrush and no interdental aids in his work bag.
Question 14
Before treatment begins, the hygienist records Mr. Osei's blood pressure at 152/94, similar to his self-reported readings. Which action best reflects joint decision-making about how to proceed?
- A. Confirm and share the reading, involve the client and dentist, and agree how to proceed.Correct answer
- B. Proceed with the full planned treatment because he reports feeling fine and has no symptoms.
- C. End the appointment immediately and tell him to return only after his physician lowers the reading.
- D. Ask the dentist to decide alone and keep the conversation brief to avoid worrying the client.
Answer
A. Confirm and share the reading, involve the client and dentist, and agree how to proceed.
Confirm and share the reading, involve the client and the dentist, and agree together how to proceed (A).
Rationale
An elevated blood pressure reading is information that changes risk without dictating a single response. Joint decision-making means the people affected — the client and the clinical team — work from the same finding. Confirming the reading rules out measurement error, sharing it respects the client's right to understand his own health information, and discussing today's care with the dentist allows the team to weigh urgency against risk. Proceeding because he feels fine subordinates recorded data to a feeling, which is precisely how elevated readings get missed. Ending the appointment entirely over one reading overshoots in the other direction, and deciding privately without the client removes him from a decision about his own body.
Why each option lands where it does
- A (correct). Confirming, sharing and agreeing turns a single measurement into a decision the client understands and the team owns together.
- B. Feeling well does not change the recorded reading, and acting on the feeling alone skips the conversation this situation requires.
- C. An abrupt shutdown withholds the finding and the reasoning from the client and forecloses options the team could agree on.
- D. Deciding without the client, even with the dentist involved, omits the person most affected from the joint decision.
Decision rule. Use recorded readings to open a joint decision with the client and relevant colleagues: verify the measurement, share it, then agree on today's care and any follow-up together.
Takeaway. When a vital sign changes the risk picture, make the decision together — confirm, share and agree — rather than deciding unilaterally or ignoring the finding.
Common miss. That a client who feels well can override a conflicting vital sign by preference alone.

Frequently asked questions
What does the free collaboration set actually contain?
Fourteen questions, split evenly. Seven are with the person receiving care and the people who support them. Seven are with other oral health professionals. Four of the fourteen use a shared case profile, so consent and roles in the profile are part of the question. The blueprint range DHPrep uses is about 11–17% of scored items.
When should a family member’s preference decide the care?
When the client cannot make that decision and the family member has authority for it. A representation agreement, a ride home, or a strong opinion does not by itself move the decision. If the stem says the client can state a capable wish today, that wish directs the plan and the family still contributes information.
How are case questions on this page related to other domains?
A case profile can contain questions that test different domains. This page prints the profile again and only the questions tagged to collaboration. Questions from the same profile that test another domain are on that domain’s page.
