PHARMACOLOGY EXAM 1 QUESTIONS

), (A+ GUARANTEE).
1. Which pharmacokinetic process is primarily affected by the ‘first-pass effect’ when a drug
is administered orally?
A. Distribution
B. Absorption
C. Excretion
D. Metabolism
Answer: D
Conceptual Explanation: The first-pass effect refers to the rapid hepatic metabolism of a
drug that occurs before it reaches the systemic circulation, which happens during the
drug’s initial pass through the liver.
2. A drug with a very high Volume of Distribution (Vd) suggests which of the following
characteristics?
A. The drug is likely sequestered in peripheral tissues or fat.
B. The drug is highly protein-bound in the plasma.
,C. The drug is confined to the intravascular compartment.
D. The drug has a short half-life.
Answer: A
Conceptual Explanation: A high Vd indicates that the drug is distributed extensively
throughout the body tissues rather than being confined to the plasma.
3. A patient is prescribed a drug that is a known CYP3A4 inducer. How will this affect a co-
administered drug that is a substrate of the same enzyme?
A. The substrate drug concentration will increase.
B. There will be no change in drug levels.
C. The substrate drug will become more toxic.
D. The substrate drug concentration will decrease.
Answer: D
Conceptual Explanation: Inducers increase the production and activity of metabolic
enzymes, leading to faster metabolism and decreased plasma concentrations of substrate
drugs.
4. Which of the following describes a ‘Full Agonist’ in pharmacodynamics?
A. A drug that binds to a receptor but produces no response.
B. A drug that binds to a receptor and produces the maximum possible response.
C. A drug that blocks the action of an endogenous ligand.
, D. A drug that requires a higher dose to achieve half-maximal effect.
Answer: B
Conceptual Explanation: A full agonist has high intrinsic activity and is capable of eliciting
the maximum response a receptor system can provide.
5. What is the primary physiological change in geriatric patients that necessitates adjusted
dosing of water-soluble drugs?
A. Increased total body water.
B. Decreased total body fat.
C. Increased serum albumin levels.
D. Decreased total body water and lean body mass.
Answer: D
Conceptual Explanation: Aging results in decreased total body water, which leads to
higher concentrations of water-soluble drugs if doses are not reduced.
6. Which schedule of controlled substances has the highest potential for abuse but also has
an accepted medical use?
A. Schedule I
B. Schedule III
C. Schedule II
D. Schedule IV
