Introduction
This comprehensive examination is designed to rigorously assess the pharmacological knowledge, clinical
reasoning, and prescribing decision-making skills essential for advanced nursing practice. The exam focuses on the
core principles of pharmacokinetics and pharmacodynamics, the safe and effective use of major drug classes, and
the application of evidence-based guidelines to real-world patient scenarios. Candidates will be challenged to
,integrate foundational theory with clinical application, considering patient-specific factors, drug interactions,
adverse effects, and monitoring parameters. The multiple-choice and scenario-based questions emphasize critical
thinking, patient safety, and the ethical-legal responsibilities inherent to prescribing and managing
pharmacotherapy across diverse populations.
SECTION ONE: QUESTIONS 1–100
1. A 55-year-old female presents with fatigue, weight gain, constipation, and cold intolerance. Laboratory
studies reveal a decreased free T4 and an elevated TSH. Which of the following is the most appropriate
initial pharmacologic treatment?
A. Levothyroxine 25 mcg daily
B. Levothyroxine 50 mcg daily
C. Methimazole 10 mg daily
D. Propylthiouracil (PTU) 50 mg daily
🟢B
🔴 RATIONALE: The patient has primary hypothyroidism. The initial dose of levothyroxine for a healthy adult is
typically 1.6 mcg/kg/day, which is approximately 50-100 mcg daily. A starting dose of 50 mcg is appropriate for
an older adult or those with cardiac risk factors. Methimazole and PTU are used for hyperthyroidism.
,2. A 68-year-old male with a history of hypertension and heart failure is prescribed lisinopril. Which of the
following is the most important adverse effect to monitor in this patient?
A. Hyperkalemia
B. Hypokalemia
C. Hyperglycemia
D. Hypoglycemia
🟢A
🔴 RATIONALE: ACE inhibitors like lisinopril can cause hyperkalemia by reducing aldosterone secretion, which
decreases potassium excretion. This is particularly important in patients with renal impairment or those taking
potassium-sparing diuretics. Hypokalemia is associated with diuretics. Hyperglycemia is associated with
corticosteroids or atypical antipsychotics.
3. A 45-year-old male is prescribed metformin for type 2 diabetes mellitus. Which of the following is the
most important pre-treatment laboratory test to assess for a contraindication to this medication?
A. Serum creatinine
B. Liver function tests (LFTs)
C. Complete blood count (CBC)
D. Hemoglobin A1c
🟢A
, 🔴 RATIONALE: Metformin is contraindicated in patients with renal impairment (eGFR < 30 mL/min) due to the
risk of lactic acidosis. Serum creatinine and eGFR should be assessed before starting therapy. LFTs are important
for monitoring but not a contraindication. CBC is not a contraindication. Hemoglobin A1c is used for monitoring
efficacy.
4. A 72-year-old female is on a warfarin regimen for atrial fibrillation. She is prescribed a new medication for
a urinary tract infection. Which of the following antibiotics is most likely to significantly increase her INR and
risk of bleeding?
A. Ciprofloxacin
B. Nitrofurantoin
C. Trimethoprim-sulfamethoxazole (TMP-SMX)
D. Amoxicillin
🟢C
🔴 RATIONALE: TMP-SMX is a strong inhibitor of CYP2C9, the enzyme responsible for metabolizing the more
active S-enantiomer of warfarin, leading to a significant increase in INR and bleeding risk. Ciprofloxacin can also
increase INR but to a lesser extent. Nitrofurantoin and amoxicillin have minimal interaction with warfarin.
5. A 35-year-old female is prescribed a selective serotonin reuptake inhibitor (SSRI) for major depressive
disorder. Which of the following is the most important counseling point regarding the onset of therapeutic
