NR565 EXAM 300 QUESTIONS AND CORRECT ANSWERS
WITH RATIONALE ALREADY GRADED A+ LATEST UPDATE
2026-2027
This 300-question practice exam is based on the NR565 Advanced
Pharmacology curriculum, covering essential pharmacotherapeutic principles
for nurse practitioners. Topics include pharmacokinetics (ADME, half-life,
steady state), pharmacodynamics (agonists, antagonists, therapeutic index),
and clinical application across major drug classes. Questions address
cardiovascular agents (ACE inhibitors, beta-blockers, diuretics, digoxin),
antimicrobials, antiepileptics, psychotropics (SSRIs, antipsychotics, lithium),
diabetes medications, opioids, and management of adverse effects and drug
interactions. Each question is presented in multiple-choice format with
detailed rationales to reinforce understanding. This comprehensive review
tests both foundational concepts and clinical prescribing knowledge,
preparing candidates for success on the NR565 advanced pharmacology
examination.
1. A patient with liver disease is prescribed a medication that undergoes extensive
first-pass metabolism. The nurse practitioner should anticipate:
A) Decreased bioavailability of the medication
B) Increased bioavailability of the medication
C) No change in bioavailability
D) Increased renal excretion
Answer: B
Rationale: First-pass metabolism occurs in the liver. In patients with liver disease,
hepatic metabolism is impaired, leading to increased bioavailability of medications
that normally undergo extensive first-pass metabolism .
2. The half-life of a medication is 4 hours. Approximately how long will it take for
the medication to reach steady state?
A) 8 hours
B) 12 hours
C) 16 hours
D) 20 hours
,Answer: D
Rationale: Steady state is achieved after approximately 5 half-lives. With a 4-hour
half-life, steady state is reached in about 20 hours .
3. A patient with renal impairment is prescribed a medication that is primarily
excreted by the kidneys. The nurse practitioner should:
A) Increase the dose
B) Decrease the dose or increase the dosing interval
C) Maintain the standard dose
D) Administer the medication intravenously
Answer: B
Rationale: In renal impairment, drug clearance is reduced. Decreasing the dose or
extending the dosing interval helps prevent drug accumulation and toxicity .
4. Which of the following describes the process by which drugs are absorbed,
distributed, metabolized, and excreted?
A) Pharmacodynamics
B) Pharmacotherapeutics
C) Pharmacokinetics
D) Pharmacogenomics
Answer: C
Rationale: Pharmacokinetics is the study of drug movement throughout the body,
including absorption, distribution, metabolism, and excretion (ADME) .
5. A drug that binds to a receptor and produces a response that is less than that of a
full agonist, even at maximal concentrations, is known as a:
A) Partial agonist
B) Inverse agonist
C) Competitive antagonist
D) Non-competitive antagonist
Answer: A
Rationale: A partial agonist has lower efficacy than a full agonist. It binds to and
activates a receptor but cannot produce a maximal response even when all
receptors are occupied .
6. A patient is taking lisinopril and reports a persistent dry cough. What is the most
likely cause?
A) Bronchospasm
B) Accumulation of bradykinin
C) Allergic reaction
,D) Angioedema
Answer: B
Rationale: ACE inhibitors prevent the breakdown of bradykinin, which can lead to
a dry cough. This is a common side effect of lisinopril and other ACE inhibitors .
7. Which laboratory value should be monitored closely in patients taking
spironolactone?
A) Sodium
B) Potassium
C) Calcium
D) Magnesium
Answer: B
Rationale: Spironolactone is a potassium-sparing diuretic and can cause
hyperkalemia. Serum potassium levels must be monitored closely .
8. A patient is prescribed a beta-blocker. Which adverse effect should the nurse
practitioner monitor for?
A) Tachycardia
B) Bradycardia
C) Hypertension
D) Hyperglycemia
Answer: B
Rationale: Beta-blockers decrease heart rate and myocardial contractility by
blocking beta-adrenergic receptors, which can result in bradycardia .
9. A patient with asthma is prescribed a beta-2 agonist. This medication works by:
A) Stimulating beta-2 receptors to cause bronchodilation
B) Blocking beta-2 receptors to cause bronchodilation
C) Stimulating alpha receptors to cause bronchodilation
D) Blocking alpha receptors to cause bronchodilation
Answer: A
Rationale: Beta-2 agonists stimulate beta-2 receptors in the bronchial smooth
muscle, causing bronchodilation. They are used for asthma and COPD .
10. What is the primary action of metformin?
A) Increases insulin secretion
B) Decreases hepatic glucose production and improves insulin sensitivity
C) Slows carbohydrate absorption
D) Increases glucose excretion
Answer: B
, Rationale: Metformin decreases hepatic glucose production and improves insulin
sensitivity in peripheral tissues. It does not increase insulin secretion .
11. A patient taking furosemide is at risk for which electrolyte imbalance?
A) Hyperkalemia
B) Hypokalemia
C) Hypernatremia
D) Hypercalcemia
Answer: B
Rationale: Furosemide is a loop diuretic that causes significant potassium loss,
leading to hypokalemia. Potassium levels should be monitored .
12. Which sign may indicate excessive levothyroxine dosing?
A) Bradycardia
B) Weight gain
C) Tachycardia
D) Hypotension
Answer: C
Rationale: Excessive levothyroxine causes symptoms of hyperthyroidism,
including tachycardia. Patients should be monitored for signs of over-replacement .
13. A patient using insulin lispro should be instructed to:
A) Eat 30 minutes after administration
B) Eat immediately after administration
C) Eat 1 hour after administration
D) Eat 2 hours after administration
Answer: B
Rationale: Insulin lispro is a rapid-acting insulin with onset of action within 15
minutes. Patients should eat immediately after administration to prevent
hypoglycemia .
14. Which medication is commonly used to treat absence seizures?
A) Phenytoin
B) Carbamazepine
C) Ethosuximide
D) Valproic acid
Answer: C
Rationale: Ethosuximide is the drug of choice for absence seizures. It works by
blocking T-type calcium channels in the thalamus .
