Walden University NURS-6521: Advanced
Pharmacology – Midterm Practice Exam (150+
Questions with Rationales)
EXAM OVERVIEW
The NURS-6521 Advanced Pharmacology midterm exam
typically consists of a 100-question exam covering Learning
Resources from Weeks 1-6. The exam is usually timed (2 to
2.5 hours) and consists of multiple-choice or multiple-
selection questions.
Key Topics Covered:
• Pharmacokinetics & Pharmacodynamics
• Pharmacogenomics
• Routes of Administration & Dosage Forms
• Medication Safety, Adverse Effects, & Drug Interactions
• Gastrointestinal Pharmacology
• Cardiovascular Pharmacology
• Respiratory Pharmacology
• Endocrine Pharmacology
, • Neurological & Musculoskeletal Pharmacology
• Legal & Ethical Prescribing
• Special Populations (Geriatrics, Pediatrics, Pregnancy,
Renal/Hepatic Impairment)
PART 1: PHARMACOKINETICS & PHARMACODYNAMICS
(Questions 1-30)
Question 1
A patient with heart failure is prescribed digoxin. Which
pharmacokinetic process is most affected by reduced renal
function?
• A) Absorption
• B) Distribution
• C) Metabolism
• D) Excretion
• Answer: D
• Rationale: Digoxin is primarily excreted unchanged by
the kidneys. Reduced renal function decreases drug
excretion, leading to accumulation and increased risk of
, digoxin toxicity. Dose adjustments based on renal
function are essential.
Question 2
A drug with a half-life of 6 hours is administered
intravenously. Approximately how long will it take to reach
steady state?
• A) 12 hours
• B) 18 hours
• C) 30 hours
• D) 48 hours
• Answer: C
• Rationale: Steady state is reached after
approximately 4–5 half-lives. 5 × 6 hours = 30 hours.
This principle applies to all drugs with linear
pharmacokinetics.
Question 3
Which statement best describes a drug with extensive first-
pass effect?
, • A) High oral bioavailability
• B) Extensive hepatic metabolism after oral
administration
• C) Rapid renal excretion
• D) High protein binding in plasma
• Answer: B
• Rationale: The first-pass effect occurs when drugs
absorbed from the small intestine are transported via
the portal system to the liver, where they undergo
extensive metabolism, usually decreasing the
bioavailability of oral medications. Drugs with high first-
pass effect require higher oral doses or alternative
routes.
Question 4
A patient with liver cirrhosis and reduced albumin
synthesis is prescribed a highly protein-bound drug. What
change in drug therapy should be anticipated?
• A) Decreased volume of distribution
• B) Increased free fraction of the drug
• C) Decreased drug half-life
