Introduction:
This comprehensive practice examination is designed to assess the advanced knowledge of pharmacology required
for success in NR 504. It evaluates a candidate's understanding of drug mechanisms, therapeutic applications,
adverse effects, and clinical decision-making in pharmacotherapy. The examination consists of 100 multiple-choice
questions, many of which are presented in a scenario-based format that tests critical thinking and clinical
reasoning. Emphasis is placed on the application of pharmacologic principles to real-world clinical situations,
including drug interactions, monitoring parameters, and patient safety considerations, to ensure the highest
standards of advanced nursing practice.
,SECTION ONE: QUESTIONS 1–100
1. A patient with hypertension is prescribed lisinopril. The patient develops a persistent dry cough. Which of the
following is the most likely mechanism for this adverse effect?
A. Increased bradykinin levels
B. Increased angiotensin II levels
C. Decreased aldosterone levels
D. Increased prostaglandin synthesis
🟢 A. Increased bradykinin levels
🔴 RATIONALE: ACE inhibitors like lisinopril block the conversion of angiotensin I to angiotensin II, which also
prevents the breakdown of bradykinin. Accumulation of bradykinin in the respiratory tract leads to a persistent
dry cough, a common side effect.
2. A patient with type 2 diabetes is started on metformin. Which of the following is the most important
laboratory parameter to monitor before initiating therapy?
A. Serum creatinine
B. Liver function tests
C. Complete blood count
D. Electrolyte levels
🟢 A. Serum creatinine
,🔴 RATIONALE: Metformin is contraindicated in patients with significant renal impairment due to the risk of
lactic acidosis. Serum creatinine should be assessed to estimate renal function (eGFR) before starting therapy
and monitored periodically.
3. A patient with heart failure is prescribed digoxin. The patient calls the clinic complaining of nausea, vomiting,
and yellow halos around lights. Which of the following is the most likely cause of these symptoms?
A. Digoxin toxicity
B. An allergic reaction
C. A gastrointestinal infection
D. An electrolyte imbalance
🟢 A. Digoxin toxicity
🔴 RATIONALE: The classic signs of digoxin toxicity include gastrointestinal symptoms (nausea, vomiting) and
visual disturbances (yellow or green halos around lights). This is a serious condition that requires immediate
evaluation.
4. A patient with asthma is prescribed an inhaled corticosteroid. Which of the following is the most important
instruction for the patient regarding the use of this medication?
A. Use the inhaler only when symptoms occur
B. Rinse the mouth after each use
C. Increase the dose if symptoms worsen
D. Use the inhaler before a bronchodilator
🟢 B. Rinse the mouth after each use
, 🔴 RATIONALE: Inhaled corticosteroids can cause oral thrush (candidiasis) and hoarseness. Rinsing the mouth
after each use reduces the risk of these side effects.
5. A patient with hypertension is prescribed a beta-blocker. Which of the following adverse effects is most
concerning in a patient with asthma?
A. Tachycardia
B. Bronchospasm
C. Hypotension
D. Hyperglycemia
🟢 B. Bronchospasm
🔴 RATIONALE: Nonselective beta-blockers can block beta-2 receptors in the lungs, leading to bronchospasm.
This is particularly dangerous in patients with asthma or COPD, as it can trigger severe respiratory distress.
6. A patient with a history of gout is prescribed allopurinol. Which of the following is the most important
instruction regarding this medication?
A. Take with food to reduce gastrointestinal upset
B. Increase fluid intake to prevent kidney stones
C. Take on an empty stomach for better absorption
D. Avoid sunlight exposure
🟢 B. Increase fluid intake to prevent kidney stones
🔴 RATIONALE: Allopurinol reduces uric acid production, which can increase the excretion of uric acid and its
metabolites in the urine. Increased fluid intake helps prevent the formation of uric acid stones in the kidneys.
