1. Which pharmacokinetic process describes the movement of a drug
from the bloodstream into tissues?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Answer: B. Distribution
Rationale: Distribution refers to the transport of drugs from the
circulation into tissues and body fluids. Absorption is the movement
from the site of administration into the bloodstream, metabolism is the
biotransformation of drugs, and excretion is the elimination of drugs
from the body.
2. Which organ is the primary site for drug metabolism?
A. Kidney
B. Liver
,2|Page
C. Lungs
D. Intestine
Answer: B. Liver
Rationale: The liver contains the cytochrome P450 enzyme system,
which is the primary site for drug metabolism. While the kidneys, lungs,
and intestines contribute to metabolism to a lesser extent, the liver is
the dominant organ for this process.
3. A drug with a half-life of 8 hours is administered at 8:00 AM. At what
time will 50% of the drug remain in the body?
A. 2:00 PM
B. 4:00 PM
C. 8:00 PM
D. Midnight
Answer: B. 4:00 PM
Rationale: Half-life is the time required for the plasma concentration of
a drug to decrease by 50%. If the half-life is 8 hours, then 8 hours after
administration (4:00 PM), 50% of the drug will remain.
4. Beta-blockers lower blood pressure primarily by:
A. Increasing heart rate
B. Blocking renin release
,3|Page
C. Increasing contractility
D. Promoting vasoconstriction
Answer: B. Blocking renin release
Rationale: Beta-1 receptor blockade in the kidneys reduces renin
secretion, which decreases angiotensin II production and subsequently
lowers blood pressure. Beta-blockers do not increase heart rate or
contractility, nor do they promote vasoconstriction.
5. Which drug is the antidote for opioid overdose?
A. Atropine
B. Naloxone
C. Protamine sulfate
D. Flumazenil
Answer: B. Naloxone
Rationale: Naloxone is a competitive opioid antagonist that binds to
opioid receptors and reverses the effects of opioid agonists, making it
the standard antidote for opioid overdose.
6. Which class of antibiotics is contraindicated in children due to the
risk of permanent teeth discoloration?
A. Penicillins
B. Macrolides
, 4|Page
C. Tetracyclines
D. Cephalosporins
Answer: C. Tetracyclines
Rationale: Tetracyclines bind to calcium in developing teeth and bones,
causing permanent discoloration and enamel hypoplasia. They are
therefore contraindicated in children under 8 years of age and in
pregnant women.
7. True or False: A focused assessment is conducted to gather data
about a specific problem that has already been identified.
Answer: True
Rationale: A focused assessment is a targeted evaluation performed
when a specific health problem has already been identified. It is
narrower in scope than a comprehensive assessment and is used to
gather detailed data about a particular issue.
8. New drug development is good at determining:
A. Efficacy
B. Safety
C. Side effects
D. Toxicity
Answer: A. Efficacy
