# NBDHE practice questions: Provision of clinical dental hygiene services

Ten original NBDHE practice questions on provision of clinical dental hygiene services, each answered on this page with a rationale and a source.

Last updated: 2026-09-08.

## Question 1

A patient with diabetes reports insulin use and no breakfast today. What information deserves communication before care?

- A. Only the year in which diabetes was diagnosed.
- B. Only the patient's preferred appointment reminder.
- C. The medication use together with the missed meal.
- D. A new insulin dose calculated by the hygienist.

**Answer C:** The medication use together with the missed meal.

ADA emphasizes medication and food-intake history because disruptions can matter during care. The facts warrant assessment, not an invented dose change. Why the other choices do not fit: A: Diagnosis date does not replace today's intake context. B: A reminder preference does not address current clinical information. D: Medication changes require appropriate clinical coordination.

**Common trap:** Separating medication from food intake.

## Question 2

Why does assessment continue during later appointments?

- A. A signed first-visit history expires after every procedure.
- B. Later examinations replace all earlier clinical records.
- C. Only a new symptom permits collection of updated history.
- D. Health, behavior and response to care can change.

**Answer D:** Health, behavior and response to care can change.

The assessment framework considers presentation, response, adherence and continuing care. A prior complete assessment is not permanent proof of unchanged circumstances. Why the other choices do not fit: A: The source does not establish that arbitrary expiration rule. B: Ongoing information complements the longitudinal record. C: ADHA describes assessment as ongoing, not symptom-only.

**Common trap:** Treating assessment as a one-time form.

## Question 3

Which sequence best reflects the dental hygiene process of care?

- A. Select services, document success, then collect baseline findings.
- B. Assess needs, formulate diagnoses, plan, implement and evaluate.
- C. Obtain a signature, repeat the usual service, then choose goals.
- D. Choose an outcome after treatment so it matches the result.

**Answer B:** Assess needs, formulate diagnoses, plan, implement and evaluate.

Assessment supplies the evidence for diagnosis and planning; evaluation then examines the outcomes of implemented care. Why the other choices do not fit: A: This reverses the role of assessment and presumes outcomes. C: Consent does not replace diagnosis or advance planning. D: Retrospective goals do not establish a meaningful evaluation plan.

**Common trap:** Starting with a favorite service.

## Question 4

Which is an evaluable behavioral goal in an original educational plan?

- A. Receive an instructional leaflet at today's visit.
- B. Be motivated to have better oral health someday.
- C. Attend every possible appointment without exception.
- D. At the agreed review, demonstrate the selected home-care skill.

**Answer D:** At the agreed review, demonstrate the selected home-care skill.

The goal identifies an observable behavior and a point for assessment. It does not promise a clinical outcome. Why the other choices do not fit: A: This documents an intervention rather than the resulting skill. B: Neither the measurement criterion nor timeframe is clear. C: This is an absolute demand unrelated to the stated skill.

**Common trap:** Confusing delivery of education with learning.

## Question 5

A goal concerns a patient's ability to manipulate a cleaning device. Which evaluation most directly addresses it?

- A. Count how many brochures the practice distributed.
- B. Confirm that the appointment charge was paid.
- C. Observe a demonstration of the agreed technique.
- D. Record whether the device has attractive packaging.

**Answer C:** Observe a demonstration of the agreed technique.

A psychomotor goal calls for evidence about performance of the skill itself. Why the other choices do not fit: A: Distribution measures an activity, not this patient's ability. B: Payment does not show the skill was learned. D: Packaging appearance does not measure technique.

**Common trap:** Measuring the convenient thing instead of the intended outcome.

## Question 6

A patient prioritizes discomfort while the chart also documents a preventive need. What is the best planning approach?

- A. Discuss both needs and coordinate their priorities.
- B. Exclude the discomfort because prevention is the course topic.
- C. Let a template determine priority without reviewing findings.
- D. Treat the concern as proof that every service is urgent.

**Answer A:** Discuss both needs and coordinate their priorities.

ADHA combines diagnosed needs, urgency, collaboration and the person's values in planning. Why the other choices do not fit: B: Person-centered planning considers the patient's concerns. C: The plan must reflect the actual assessment and urgency. D: A complaint alone does not establish the urgency of all care.

**Common trap:** Ignoring either the assessment or the patient.

## Question 7

Which part of a goal is missing from “the patient will demonstrate the chosen method correctly”?

- A. The brand's retail price.
- B. An agreed timeframe for evaluation.
- C. A promise that all disease will disappear.
- D. A fixed number of appointments for every patient.

**Answer B:** An agreed timeframe for evaluation.

The statement suggests an observable behavior but does not specify when it will be evaluated. Why the other choices do not fit: A: Price is not a required goal-measurement component. C: A guarantee is neither necessary nor supported. D: Visit counts should be individualized to the plan.

**Common trap:** Writing an outcome without a review point.

## Question 8

New assessment information changes the services proposed for today. What should precede implementation of the revised plan?

- A. Use the old signature as approval of any additional service.
- B. Perform the new service before mentioning the change.
- C. Remove the new information to preserve the original plan.
- D. Explain the revision and obtain the needed informed agreement.

**Answer D:** Explain the revision and obtain the needed informed agreement.

ADHA calls for review of the plan, appropriate modification, understanding and consent before implementation. Why the other choices do not fit: A: Prior agreement is not unrestricted consent to changed care. B: Informed decision-making precedes implementation. C: Relevant findings must inform care rather than be concealed.

**Common trap:** Treating consent as a permanent blank check.

## Question 9

A patient declines a proposed service after discussion. Which documentation best preserves the event?

- A. Record that all services were accepted to simplify the chart.
- B. Remove the discussion because no service occurred.
- C. Record the informed discussion and the declined service.
- D. Describe the declined service as already completed.

**Answer C:** Record the informed discussion and the declined service.

The record should accurately reflect informed refusal and the related communication. Why the other choices do not fit: A: This falsely represents the patient's decision. B: Communications and informed refusal remain clinically relevant. D: A proposed intervention is not a performed intervention.

**Common trap:** Erasing a decision that changes the plan.

## Question 10

At review, the agreed approach has not addressed a documented functional barrier. What is the appropriate use of evaluation?

- A. Repeat the same plan indefinitely because it was signed.
- B. Declare success because instructions were delivered.
- C. Discard the patient's report when measurements exist.
- D. Reassess the barrier and consider modifying the approach.

**Answer D:** Reassess the barrier and consider modifying the approach.

Evaluation can support continuing, changing or discontinuing elements of care based on evidence. Why the other choices do not fit: A: A prior plan should respond to new outcome information. B: Intervention delivery is not proof of goal attainment. C: Patient-reported outcomes contribute a distinct perspective.

**Common trap:** Making follow-up an automatic repeat.
