*Core Domains*
Pharmacokinetics and Pharmacodynamics in Critical Care
Autonomic Nervous System Agents
Cardiovascular Pharmacology and Hemodynamics
Endocrine and Metabolic Management

Pain Management and Anxiolysis in the ICU
Neurological and Sedation Pharmacology
Renal and Hepatic Dosing Considerations
Regulatory Standards and Ethical Prescribing
*Introduction*
,The purpose of this final examination is to rigorously evaluate the advanced clinical
pharmacology knowledge required for the Adult-Gerontology Acute Care Nurse Practitioner
(AGACNP). This assessment measures proficiency in drug selection, titration, and
monitoring within high-acuity environments. Candidates will encounter a comprehensive
range of multiple-choice and complex scenario-based questions designed to test the
application of pharmacotherapeutic principles to patient safety. The exam places a heavy
emphasis on evidence-based decision-making, regulatory compliance, and the critical
analysis of real-world clinical dilemmas to ensure the practitioner is prepared to optimize
patient outcomes across diverse acute care settings.
Section One: Questions 1–100
Question 1
A patient in the ICU requires initiation of norepinephrine for septic shock. Which receptor
profile primarily explains its clinical effect?
A. Selective Beta-1 agonism
B. Alpha-1 and Beta-1 agonism
C. Pure Alpha-2 antagonism
D. Selective Dopaminergic agonism
🟢 B. Alpha-1 and Beta-1 agonism
🔴 Explanation: Norepinephrine is a potent vasopressor that primarily stimulates Alpha-1
receptors (causing vasoconstriction) and Beta-1 receptors (providing moderate inotropic
,support), making it the first-line choice for septic shock.
Question 2
Which medication is contraindicated in a patient with a known history of severe asthma
due to the risk of bronchospasm?
A. Labetalol
B. Metoprolol tartrate
C. Propranolol
D. Carvedilol
🟢 C. Propranolol
🔴 Explanation: Propranolol is a non-selective beta-blocker that blocks both Beta-1 and
Beta-2 receptors. Blocking Beta-2 receptors in the lungs can cause bronchoconstriction,
which is dangerous for patients with reactive airway disease.
Question 3
A 72-year-old patient with renal insufficiency (CrCl 25 mL/min) requires an antibiotic. Which
agent requires a significant dose reduction to prevent drug accumulation?
A. Ceftriaxone
B. Vancomycin
C. Azithromycin
D. Doxycycline
, 🟢 B. Vancomycin
🔴 Explanation: Vancomycin is renally cleared, and patients with significantly reduced
creatinine clearance require adjusted dosing or extended intervals based on trough levels
to prevent nephrotoxicity and ototoxicity.
Question 4
What is the primary mechanism of action of dexmedetomidine when used for sedation in
the ventilated patient?
A. GABA-A receptor modulation
B. Selective Alpha-2 adrenergic agonism
C. NMDA receptor antagonism
D. Mu-opioid receptor agonism
🟢 B. Selective Alpha-2 adrenergic agonism
🔴 Explanation: Dexmedetomidine provides sedation and analgesia without significant
respiratory depression by acting as a selective Alpha-2 agonist in the brainstem, which
inhibits norepinephrine release.
Question 5
A patient is receiving heparin infusion for PE. The PTT is 120 seconds. What is the most
appropriate immediate action?
