SECTION 1: Pharmacokinetics & Pharmacodynamics
(Questions)
1. A drug with a half-life of 8 hours is administered every 8
hours. Approximately how long will it take to reach steady
state?
A. 8 hours
B. 16 hours
C. 32–40 hours (4–5 half-lives)
D. 80 hours
Answer: C
Rationale: Steady state is reached after approximately 4–5 half-
lives. For a drug with an 8-hour half-life, steady state is reached
in 32–40 hours.
2. What is the primary determinant of drug distribution to
tissues?
A. Gastric pH
B. Blood flow, tissue permeability, and protein binding
C. Renal function
D. Liver enzyme activity
,https://www.stuvia.com/user/performance
Answer: B
Rationale: Drug distribution depends on blood flow to tissues,
tissue permeability, plasma protein binding, and lipid solubility
of the drug.
3. A patient is prescribed a highly protein-bound drug. Which
condition would increase the free (active) drug concentration?
A. Hyperalbuminemia
B. Hypoalbuminemia (low albumin)
C. Increased liver function
D. Increased renal function
Answer: B
Rationale: Hypoalbuminemia decreases available binding sites,
increasing the free (active) fraction of highly protein-bound
drugs, potentially causing toxicity.
4. What is the difference between potency and efficacy?
A. Potency is the maximum effect; efficacy is the dose needed
B. Potency is the dose needed for an effect; efficacy is the
maximum effect achievable
C. They are the same
D. Potency is always more important than efficacy
, https://www.stuvia.com/user/performance
Answer: B
Rationale: Potency refers to the amount of drug needed to
produce an effect (lower dose = higher potency). Efficacy is the
maximum effect a drug can produce regardless of dose.
5. What does the therapeutic index (TI) indicate?
A. The cost of a drug
B. The ratio of toxic dose to therapeutic dose (larger TI = safer
drug)
C. The duration of action
D. The rate of absorption
Answer: B
Rationale: Therapeutic index = TD50/ED50 (or LD50/ED50). A
larger TI indicates a wider margin of safety between therapeutic
and toxic doses.
6. Which of the following drugs has a narrow therapeutic
index requiring monitoring?
A. Amoxicillin
B. Warfarin
C. Metformin
D. Lisinopril
