, SECTION 1: Basic Concepts in Pharmacology
Q1. A 45-year-old patient is started on a new medication that is highly protein-bound. Laboratory results show
significantly decreased serum albumin levels due to chronic liver disease. The nurse practitioner must anticipate
an alteration in which pharmacokinetic process to prevent toxicity?
A. Distribution of the free (unbound) drug to target tissues
B. Absorption of the drug from the gastrointestinal tract
C. First-pass metabolism in the hepatic portal system
D. Renal tubular reabsorption of the parent compound
Correct Answer: A
Rationale: Highly protein-bound drugs exist in equilibrium between bound and free forms. When albumin is low, more free
drug is available for distribution to tissues, increasing the risk of toxicity. Absorption and first-pass metabolism are not directly
altered by serum albumin concentration.
Q2. A medication is described as having a narrow therapeutic index. During patient education, the pharmacist
emphasizes the importance of regular blood level monitoring. This characteristic primarily indicates which
relationship between the drug’s effective dose and toxic dose?
A. The median effective dose is far below the median lethal dose
B. The drug exhibits zero-order kinetics at all therapeutic concentrations
C. The ratio of the toxic dose to the effective dose is relatively small
D. Receptor saturation occurs only at supra-therapeutic plasma levels
Correct Answer: C
Rationale: A narrow therapeutic index means the toxic dose is only slightly higher than the effective dose, requiring careful
monitoring. Option A describes a wide therapeutic index. Zero-order kinetics and receptor saturation are separate
pharmacologic concepts.
Q3. A patient receives an intravenous bolus of a drug that follows first-order elimination kinetics. After three
half-lives have elapsed, approximately what percentage of the original dose remains in the body?
A. 50%
B. 12.5%
C. 25%
D. 6.25%
Correct Answer: B
Rationale: In first-order kinetics, 50% is eliminated each half-life. After one half-life 50% remains, after two 25% remains, and
after three half-lives 12.5% remains. This exponential decline is characteristic of most therapeutic drugs.
Q4. A newly prescribed oral antibiotic is known to undergo extensive first-pass metabolism. The physician
increases the oral dose relative to the intravenous dose that would achieve the same plasma concentration. This
adjustment compensates for which primary pharmacokinetic phenomenon?
A. Increased volume of distribution secondary to tissue binding
B. Accelerated renal clearance caused by tubular secretion
C. Delayed gastric emptying that prolongs absorption time
D. Reduced bioavailability due to hepatic extraction before systemic circulation
Correct Answer: D
