1. A patient with hepatic cirrhosis has a reduced ability to metabolize
drugs. Which pharmacokinetic process is most directly affected?
A) Absorption
B) Distribution
C) Metabolism — CORRECT ANSWER
D) Excretion
Rationale: The liver is the primary site of drug metabolism
(biotransformation). Cirrhosis impairs phase I (oxidation, reduction,
,hydrolysis) and phase II (conjugation) reactions, leading to drug
accumulation and toxicity. Excretion is primarily renal.
2. A drug has a half-life of 24 hours. How many hours will it take to
reach steady state if the patient takes the drug once daily?
A) 24 hours
B) 48 hours
C) 96 hours
D) 120 hours — CORRECT ANSWER
Rationale: Steady state is achieved after approximately 4–5 half-lives.
With a 24-hour half-life, steady state occurs at 4–5 days (96–120
hours). Once-daily dosing means steady state is reached after 4–5
doses.
3. Which of the following drug properties results in a large volume of
distribution (Vd)?
A) High water solubility
,B) High protein binding
C) High lipophilicity — CORRECT ANSWER
D) Large molecular weight
Rationale: Lipophilic drugs cross cell membranes easily and
distribute into tissues, resulting in a large Vd (>0.6 L/kg). Water-
soluble drugs remain in the vascular space (low Vd).
4. A medication that acts as an antagonist at the mu-opioid receptor
will have which effect?
A) Analgesia
B) Respiratory depression
C) Blockade of opioid effects — CORRECT ANSWER
D) Euphoria
, Rationale: An antagonist binds to a receptor but does not activate it;
it blocks the action of agonists. Naloxone is a mu-opioid antagonist
used to reverse opioid overdose. Agonists produce analgesia,
respiratory depression, and euphoria.
5. A drug with zero-order kinetics:
A) Has a constant half-life regardless of dose
B) Eliminates a constant amount per unit time — CORRECT
ANSWER
C) Follows first-order elimination at high doses
D) Is never clinically relevant
Rationale: Zero-order kinetics means a constant amount of drug is
eliminated per unit time (e.g., ethanol, phenytoin at high doses).
Half-life is not constant and increases with dose.
6. A patient is taking two drugs that are both highly protein-bound
(warfarin and sulfamethoxazole). What is the potential interaction?
