SECTION A: PHARMACOKINETICS & PHARMACODYNAMICS
QUESTION 1
Which process describes what the body does to a drug, including
absorption, distribution, metabolism, and excretion?
,A. Pharmacodynamics
B. Pharmacogenetics
C. Pharmacokinetics
D. Pharmacotherapeutics
ANSWER: C. Pharmacokinetics
EXPLANATION: Pharmacokinetics (PK) refers to the movement of a
drug through the body (what the body does to the drug), whereas
pharmacodynamics is what the drug does to the body .
QUESTION 2
A patient with a low serum albumin level is prescribed a highly protein-
bound drug. What is the main concern for this patient?
A. Rapid renal excretion
B. Decreased therapeutic effect
C. Increased risk of drug toxicity
D. Reduced drug absorption
ANSWER: C. Increased risk of drug toxicity
EXPLANATION: Low albumin means fewer binding sites, leading to
more free (active) drug in the bloodstream, which increases the
risk of toxicity .
QUESTION 3
Which enzyme system in the liver is most commonly responsible for the
metabolism of the majority of drugs?
,A. MAO system
B. Cholinesterase system
C. Glucuronidation system
D. Cytochrome P450 system
ANSWER: D. Cytochrome P450 system
EXPLANATION: The Cytochrome P450 (CYP450) enzyme system is
the primary pathway for hepatic drug metabolism .
QUESTION 4
What is the primary site of drug excretion in the human body?
A. Kidneys
B. Liver
C. Lungs
D. Skin
ANSWER: A. Kidneys
EXPLANATION: While some drugs are excreted via bile or sweat, the
kidneys are the main organ responsible for drug excretion .
QUESTION 5
Which of the following describes the 'First-Pass Effect'?
A. Rapid renal clearance of a drug after the first dose
B. The binding of a drug to plasma proteins
C. Metabolism of an oral drug in the liver before reaching systemic
circulation
, D. The time it takes for a drug to reach steady state
ANSWER: C. Metabolism of an oral drug in the liver before reaching
systemic circulation
EXPLANATION: Oral drugs are absorbed in the GI tract and pass
through the liver via the portal vein, where they may be significantly
metabolized before entering systemic circulation .
QUESTION 6
How many half-lives does it typically take for a drug to reach steady-state
concentration?
A. 1 to 2
B. 2 to 3
C. 4 to 5
D. 7 to 10
ANSWER: C. 4 to 5
EXPLANATION: It generally takes 4 to 5 half-lives for a drug to reach
a plateau or steady-state concentration in the plasma .
QUESTION 7
Which pregnancy category indicates that studies in animals or humans
have demonstrated fetal abnormalities or risks that clearly outweigh any
possible benefit?
A. Category X
B. Category C
