Choose the single best answer (A–D). Each item is followed by a keyed answer and rationale. Questions cover
advanced clinical practice, consultation, evidence-based practice, leadership, quality improvement, patient safety,
ethics, and systems change.
Practice Questions
1. A unit reports a rise in central-line infections. What should the clinical nurse specialist do first?
A. Discipline the entire unit immediately
B. Review surveillance data and current prevention practices with the interprofessional team
C. Assume the increase is random without analysis
D. Stop collecting infection data
Correct answer: B. Review surveillance data and current prevention practices with the interprofessional team
Rationale: CNS-led improvement begins with reliable data and collaborative analysis of potential clinical and system
contributors.
2. A patient deteriorates despite the current care plan. What is the priority?
A. Support rapid reassessment and escalation based on the patient's condition
B. Continue the plan unchanged until discharge
C. Complete a quality report before helping the patient
D. Wait for the next scheduled case conference
Correct answer: A. Support rapid reassessment and escalation based on the patient's condition
Rationale: Immediate patient safety comes first; stabilize and escalate care, then review contributing system factors.
3. A nurse seeks help interpreting a complex presentation. What is the best CNS response?
A. Take over all future decisions without explanation
B. Provide evidence-informed consultation and support the nurse's clinical reasoning

B. Use the abstract alone as proof
C. Appraise study quality and the wider evidence base before recommending change
D. Reject all research that is not randomized
Correct answer: C. Appraise study quality and the wider evidence base before recommending change
Rationale: Evidence-based practice requires critical appraisal and consideration of applicability and the totality of evidence.
7. Several services give conflicting recommendations to a patient with complex chronic illness. What
should the CNS promote?
A. Interprofessional coordination around patient goals and a reconciled care plan
B. Separate plans with no communication
C. A plan based only on departmental convenience
D. Discontinuation of chronic disease follow-up
Correct answer: A. Interprofessional coordination around patient goals and a reconciled care plan
Rationale: Coordinated care reduces fragmentation and aligns treatment with patient priorities.
8. A staff member reports a near miss involving a high-alert medication. What is the best response?
A. Blame the last person involved without reviewing the process
B. Report and analyze the near miss to identify safeguards and learning opportunities
C. Stop all medication administration indefinitely
D. Hide it because no harm occurred
Correct answer: B. Report and analyze the near miss to identify safeguards and learning opportunities
Rationale: Near-miss reporting supports proactive risk reduction and system learning.

understanding?
A. Use teach-back to assess whether the patient can explain the plan
B. Measure how quickly the educator finishes

D. Count the number of presentation slides
Correct answer: A. Use teach-back to assess whether the patient can explain the plan
Rationale: Outcome measures should match the program's purpose; teach-back evaluates comprehension.

interpretation?
A. Report only the most favorable time point
B. Conclude the intervention alone caused all improvement
C. Discard the data without review
D. Consider confounding and strengthen evaluation where feasible
