Introduction
This comprehensive examination practice guide is designed to prepare
nurse practitioner candidates for the College of Nurses of Ontario
registration examination. The assessment rigorously evaluates advanced
clinical judgment, diagnostic reasoning, and specialized knowledge
required for autonomous practice. Candidates will encounter a robust mix
of multiple-choice items and complex clinical scenarios that test both
theoretical mastery and practical application. Special emphasis is placed
on real-world decision-making, patient safety, legal compliance, and
adherence to professional standards of practice. This resource ensures
candidates are fully equipped to demonstrate safe, competent, and
ethical care within diverse healthcare environments.
Question 1
A nurse practitioner evaluates an older adult client presenting with acute
confusion and a low-grade fever. Urinalysis confirms a urinary tract
infection. Which of the following foundational pharmacological principles
should guide initial antimicrobial selection?
A. Prescribing broad-spectrum antibiotics empirically without culture
results to ensure immediate symptom eradication.
B. Selecting an agent based on local antibiogram data, client renal
function, and targeted pathogen sensitivities.
C. Utilizing the highest recommended therapeutic dose to overcome
potential microbial resistance rapidly.
D. Administering prophylactic combination therapy to prevent secondary
opportunistic infections.
,B. Selecting an agent based on local antibiogram data, client renal
function, and targeted pathogen sensitivities.
🔴 Explanation: Evidence-based prescribing requires utilizing local
resistance patterns and individual client pharmacokinetic profiles, such as
renal clearance, to maximize efficacy while minimizing adverse effects
and resistance.
Question 2
An adult client requests a referral for complementary therapy to manage
chronic lower back pain alongside conventional medical management.
What is the primary ethical responsibility of the nurse practitioner in this
scenario?
A. Discouraging the use of complementary modalities due to a lack of
standardized regulation.
B. Providing evidence-based information regarding potential benefits and
risks while supporting informed choice.
C. Delegating the assessment of complementary therapies entirely to a
physiotherapist.
D. Recommending specific unregulated products based on anecdotal
peer success.
🟢 B. Providing evidence-based information regarding potential benefits
and risks while supporting informed choice.
🔴 Explanation: Nurse practitioners must uphold client autonomy by
offering objective, evidence-based guidance on complementary
treatments, ensuring safe integration into the broader care plan.
Question 3
A nurse practitioner notices a colleague consistently documenting
assessments before physical examinations are actually performed.
According to professional regulatory standards, what is the mandatory
initial course of action?
A. Report the colleague immediately to the provincial licensing board
without prior discussion.
B. Ignore the practice if patient outcomes have not been overtly
compromised.
C. Discuss the professional implications of falsifying documentation
directly and privately with the colleague.
D. Document the discrepancies in the client charts under an anonymous
identifier.
,C. Discuss the professional implications of falsifying documentation
directly and privately with the colleague.
🔴 Explanation: Regulatory standards encourage addressing
professional practice concerns directly with the colleague first, provided
public safety is not in immediate, severe jeopardy, before escalating
through formal institutional or regulatory channels.
Question 4
A primary care nurse practitioner is designing a community health
initiative to reduce type 2 diabetes prevalence in a high-risk demographic.
Which intervention represents secondary prevention?
A. Implementing a community-wide educational campaign regarding
healthy nutritional habits and regular exercise.
B. Establishing a screening clinic for fasting blood glucose and HbA1c
testing in asymptomatic high-risk individuals.
C. Providing advanced clinical management and lifestyle modification
counseling for newly diagnosed clients.
D. Organizing support groups to prevent long-term microvascular
complications in established diabetic clients.
🟢 B. Establishing a screening clinic for fasting blood glucose and HbA1c
testing in asymptomatic high-risk individuals.
🔴 Explanation: Secondary prevention focuses on early detection and
prompt intervention for asymptomatic individuals who have risk factors or
preclinical disease to halt or slow disease progression.
Question 5
A client with terminal cancer expresses a clear desire to stop life-
prolonging treatments and requests palliative comfort measures only. The
family strongly opposes this decision, demanding that all aggressive
interventions continue. How should the nurse practitioner navigate this
conflict?
A. Yield to the family demands since they are legally designated as the
primary next of kin.
B. Discontinue life-prolonging treatments immediately without further
family consultation.
C. Uphold the competent client's autonomous decision while providing
supportive counseling to the family.
D. Obtain a mandatory court order to override the client refusal of
treatment.
, C. Uphold the competent client's autonomous decision while providing
supportive counseling to the family.
🔴 Explanation: A mentally competent client holds the legal and ethical
right to accept or refuse medical treatment. The nurse practitioner must
advocate for the client's autonomy while facilitating compassionate
communication with the family.
Question 6
During a routine prenatal examination, a client at 28 weeks gestation
presents with a blood pressure of 145/95 mmHg on two occasions four
hours apart, accompanied by new-onset trace proteinuria. What is the
most appropriate management strategy?
A. Reassure the client that mild blood pressure elevation is normal in the
third trimester and schedule a routine follow-up in four weeks.
B. Initiate outpatient monitoring and refer the client urgently for
specialized maternal-fetal assessment regarding gestational
hypertension.
C. Immediately prescribe high-dose systemic corticosteroids to accelerate
fetal lung maturity.
D. Advise strict bed rest at home with self-monitoring of blood pressure
twice weekly.
🟢 B. Initiate outpatient monitoring and refer the client urgently for
specialized maternal-fetal assessment regarding gestational
hypertension.
🔴 Explanation: New-onset hypertension after 20 weeks gestation with
proteinuria warrants urgent investigation and consultation to monitor for
progression to preeclampsia and ensure maternal-fetal safety.
Question 7
A nurse practitioner working in an emergency department suspects a
case of elder abuse after observing unexplained contusions and fearful
behavior in an older adult client accompanied by an aggressive caregiver.
What is the legal and professional obligation?
A. Maintain client confidentiality by documenting observations internally
without external reporting.
B. Confront the caregiver directly regarding the suspected abuse before
taking further action.
C. Comply with mandatory reporting legislation by notifying the
