NURS 6521N WEEK 3 ADVANCED
PHARMACOLOGY EXAM QUESTIONS
WITH COMPLETE AND VERIFIED
SOLUTIONS: WALDEN UNIVERSITY
1. A patient with hypoalbuminemia is prescribed a highly protein-bound medication. Which
of the following pharmacokinetic outcomes should the nurse practitioner anticipate?
A. Increased risk of drug toxicity due to higher free drug levels
B. Decreased bioavailability of the drug
C. Reduced volume of distribution
D. Increased rate of hepatic metabolism
Answer: A
Conceptual Explanation: Low albumin levels result in fewer binding sites for highly
protein-bound drugs, leading to an increase in the concentration of free (active) drug in the
plasma, which increases the risk of toxicity.
2. Which pharmacokinetic process is most significantly affected by the ‘first-pass effect’ in an
orally administered medication?
A. Excretion
B. Absorption
,C. Distribution
D. Metabolism
Answer: D
Conceptual Explanation: The first-pass effect refers to the metabolism of a drug by the
liver after being absorbed from the gastrointestinal tract and before it reaches systemic
circulation.
3. In geriatric patients, the reduction in total body water and increase in body fat typically
result in which of the following regarding lipid-soluble drugs?
A. Decreased half-life and faster clearance
B. Decreased volume of distribution
C. Increased peak plasma concentrations
D. Increased volume of distribution and prolonged half-life
Answer: D
Conceptual Explanation: Increased body fat in older adults provides a larger reservoir for
lipid-soluble drugs, increasing their volume of distribution and extending the time required
for elimination (half-life).
, 4. A patient is taking a drug that is a known Cytochrome P450 (CYP) enzyme inducer. If a
second drug metabolized by the same enzyme is added, what is the most likely result for the
second drug?
A. Increased plasma levels and toxicity
B. Decreased plasma levels and reduced therapeutic effect
C. No change in drug levels
D. Increased binding to plasma proteins
Answer: B
Conceptual Explanation: Enzyme inducers speed up the metabolism of other drugs
metabolized by the same enzyme system, leading to lower plasma concentrations and
potentially subtherapeutic effects.
5. What is the primary reason why neonates and infants are at a higher risk for drug toxicity
compared to adults?
A. Rapid gastric emptying
B. Increased glomerular filtration rate (GFR)
C. Higher levels of plasma protein binding
D. Immature hepatic enzymes and renal function
Answer: D
