• INTRODUCTION *
• The NU 641 Advanced Clinical Pharmacology Examination assesses
graduate nursing students' mastery of pharmacologic principles essential for
advanced practice. It evaluates pharmacokinetics, pharmacodynamics, drug
classifications, prescribing regulations, and patient safety. The exam uses
multiple-choice and scenario-based questions requiring clinical judgment
and evidence-based decision-making. Emphasis is placed on adverse
effects, drug interactions, special populations, and legal prescribing
standards. Successful performance demonstrates readiness to prescribe
and monitor pharmacologic therapy safely and effectively in diverse clinical
settings. *
SECTION ONE: QUESTIONS 1–100
Question 1
A 68-year-old male with hypertension and chronic kidney disease (creatinine
clearance 28 mL/min) is prescribed a new medication. Which pharmacokinetic
parameter is most important to consider when determining the dose?
A. Volume of distribution
B. Protein binding
C. Renal clearance
D. Hepatic first-pass effect
, RATIONALE: Renal clearance is critical in patients with chronic kidney disease
because reduced kidney function leads to drug accumulation and increased risk of
toxicity. Dose adjustment is often required.
Question 2
A 45-year-old female is prescribed a drug that is a potent inducer of CYP3A4.
Which of the following effects is most likely to occur when she also takes a
medication metabolized by CYP3A4?
A. Increased serum concentration of the CYP3A4 substrate
B. Decreased serum concentration of the CYP3A4 substrate
C. No change in serum concentration
D. Increased risk of toxicity from the CYP3A4 substrate
RATIONALE: CYP3A4 inducers increase the metabolism of substrate drugs,
leading to decreased serum concentrations and potentially reduced therapeutic
effect.
Question 3
A 72-year-old female is started on warfarin for atrial fibrillation. Which laboratory
test should be monitored to assess therapeutic effectiveness?
A. Activated partial thromboplastin time (aPTT)
B. International normalized ratio (INR)
C. Bleeding time
D. Platelet count
RATIONALE: Warfarin therapy is monitored with the INR. The target INR for atrial
fibrillation is typically 2.0–3.0.
Question 4
A 30-year-old male with a history of opioid use disorder is prescribed
buprenorphine. What is the primary mechanism of action of this medication?
A. Full mu-opioid receptor agonist
B. Partial mu-opioid receptor agonist
, C. Mu-opioid receptor antagonist
D. NMDA receptor antagonist
RATIONALE: Buprenorphine is a partial mu-opioid agonist, which provides
analgesia and reduces cravings while limiting respiratory depression compared to
full agonists.
Question 5
A 55-year-old female with type 2 diabetes is prescribed metformin. Which of the
following is a rare but serious adverse effect of this medication?
A. Hypoglycemia
B. Weight gain
C. Lactic acidosis
D. Hyperkalemia
RATIONALE: Lactic acidosis is a rare but life-threatening adverse effect of
metformin, especially in patients with renal impairment or other risk factors.
Question 6
A 28-year-old pregnant female requires treatment for a urinary tract infection.
Which antibiotic is safest during pregnancy?
A. Doxycycline
B. Ciprofloxacin
C. Nitrofurantoin
D. Trimethoprim-sulfamethoxazole
RATIONALE: Nitrofurantoin is generally considered safe for uncomplicated UTIs
in pregnancy, especially in the first and second trimesters. Doxycycline and
fluoroquinolones are contraindicated.
Question 7
A 62-year-old male is prescribed atorvastatin. Which laboratory test should be
monitored to assess for hepatotoxicity?
