Introduction
This comprehensive assessment evaluates advanced
pharmacological knowledge required for Adult-Gerontology Acute
Care Nurse Practitioners. The examination covers pharmacokinetics,
pharmacodynamics, major drug classifications, therapeutic
monitoring, drug interactions, adverse effects, and evidence-based
prescribing. Questions are structured as multiple-choice and
scenario-based items emphasizing real-world clinical application,
critical decision-making, and patient safety. Candidates must
demonstrate competency in prescribing, monitoring, and managing
complex medication regimens in acutely ill adult and geriatric
populations. Each item requires application of pharmacological
principles consistent with advanced practice nursing standards.
,SECTION ONE: QUESTIONS 1–100
1. A patient is prescribed a drug that is highly protein-bound.
The patient has hypoalbuminemia from liver disease. What
effect will this have on the free drug concentration?
A. Decreased free drug concentration
B. Increased free drug concentration
C. No change in free drug concentration
D. Complete elimination of free drug
🟢 Correct answer: B. Increased free drug concentration
🔴 RATIONALE: Highly protein-bound drugs bind primarily to
albumin. In hypoalbuminemia, fewer binding sites are available,
leading to an increased free (unbound) fraction of the drug. This
increases pharmacological effect and risk of toxicity. Dose
adjustments are often required.
2. Which pharmacokinetic parameter describes the fraction of
an administered drug dose that reaches systemic circulation
unchanged?
A. Volume of distribution
B. Bioavailability
C. Clearance
D. Half-life
,🟢 Correct answer: B. Bioavailability
🔴 RATIONALE: Bioavailability is the fraction of an administered
dose that reaches systemic circulation unchanged. Intravenous
administration has 100% bioavailability. Oral bioavailability is
affected by first-pass metabolism, absorption, and formulation.
3. A 78-year-old patient with atrial fibrillation is prescribed
warfarin. Which factor most increases this patient's bleeding
risk?
A. Increased lean body mass
B. Decreased hepatic metabolism
C. Increased renal clearance
D. Increased albumin levels
🟢 Correct answer: B. Decreased hepatic metabolism
🔴 RATIONALE: Aging decreases hepatic blood flow and enzyme
activity, reducing metabolism of warfarin and prolonging its
effect. This increases bleeding risk. Geriatric patients require lower
doses and frequent INR monitoring.
4. A patient is receiving intravenous furosemide. Which
electrolyte abnormality is most concerning?
A. Hypernatremia
B. Hypokalemia
, C. Hypercalcemia
D. Hyperphosphatemia
🟢 Correct answer: B. Hypokalemia
🔴 RATIONALE: Loop diuretics such as furosemide cause
significant potassium loss by inhibiting sodium-potassium-
chloride cotransport in the loop of Henle. Hypokalemia can cause
cardiac dysrhythmias, muscle weakness, and digitalis toxicity.
5. A patient with sepsis is prescribed norepinephrine. What is
the primary mechanism of action?
A. Beta-1 receptor agonism
B. Alpha-1 receptor agonism
C. Beta-2 receptor agonism
D. Alpha-2 receptor agonism
🟢 Correct answer: B. Alpha-1 receptor agonism
🔴 RATIONALE: Norepinephrine primarily stimulates alpha-1
receptors, causing vasoconstriction and increased blood pressure.
It also has some beta-1 activity. It is first-line vasopressor for
septic shock.
6. A patient is started on lisinopril. Which adverse effect requires
immediate discontinuation?
