1. A patient with liver cirrhosis has a reduced serum albumin level. What is the most
significant pharmacokinetic implication for highly protein-bound drugs?
A. Increased free drug levels leading to potential toxicity
B. Decreased bioavailability of the drug
C. Enhanced renal excretion of the drug
D. Decreased drug distribution to target tissues
Answer: A
Conceptual Explanation: Albumin acts as a carrier; if levels are low, there are fewer
binding sites, increasing the concentration of free (active) drug, which can lead to toxicity.
2. Which process describes the movement of a drug from its site of administration into the
bloodstream?
A. Distribution
B. Metabolism
C. Absorption
,D. Excretion
Answer: C
Conceptual Explanation: Absorption is the primary process of moving a drug into the
systemic circulation from the administration site.
3. A drug that has a very high ‘First-Pass Effect’ should ideally be administered via which
route to ensure therapeutic levels?
A. Oral
B. Intranasal
C. Sublingual
D. Transdermal
Answer: C
Conceptual Explanation: Sublingual administration bypasses the liver’s portal circulation,
avoiding the extensive metabolism that occurs with the first-pass effect associated with
oral ingestion.
4. What is the primary site for drug metabolism in the human body?
A. Liver
B. Lungs
C. Kidneys
D. Small Intestine
, Answer: A
Conceptual Explanation: The liver is the principal organ for metabolism, utilizing the
Cytochrome P450 enzyme system.
5. If a drug has a half-life of 4 hours, how much of a 100mg dose remains in the body after 12
hours?
A. 50mg
B. 12.5mg
C. 25mg
D. 6.25mg
Answer: B
Conceptual Explanation: After one half-life (4h): 50mg; two (8h): 25mg; three (12h):
12.5mg.
6. Which term describes a drug’s ability to activate a receptor after binding?
A. Affinity
B. Potency
C. Intrinsic Activity
D. Therapeutic Index
Answer: C
