EXAM 1: Foundations of Psychopharmacology
Section A: Pharmacokinetics & Pharmacodynamics
1. Which process describes the movement of a drug from the site of administration into the
bloodstream?
A. Distribution
B. Absorption
C. Metabolism
D. Excretion
ANSWER: B
Rationale: Absorption is the primary pharmacokinetic process where a drug moves from its entry point
into systemic circulation. This process is influenced by the drug's lipid solubility and the pH of the
environment.
,2. What does pharmacokinetics describe?
A. The drug's effect on the body
B. How the body processes the drug
C. The drug's chemical composition
D. The therapeutic outcome
ANSWER: B
Rationale: Pharmacokinetics involves absorption, distribution, metabolism, and excretion (ADME)—
what the body does to the drug. Pharmacodynamics is what the drug does to the body.
3. A nurse practitioner explains to a patient that "what the body does to the drug" is known as:
A. Pharmacodynamics
B. Pharmacokinetics
C. Pharmacotherapeutics
D. Pharmacogenomics
ANSWER: B
Rationale: Pharmacokinetics describes ADME processes. Pharmacodynamics refers to receptor binding
and effects. Pharmacotherapeutics is the use of drugs to treat disease, and pharmacogenomics studies
genetic variations in drug response.
,4. In signal transduction, which enzyme is responsible for the degradation of cyclic adenosine
monophosphate (cAMP)?
A. Protein Kinase A
B. Adenylate Cyclase
C. Monoamine Oxidase
D. Phosphodiesterase
ANSWER: D
Rationale: Phosphodiesterase breaks down second messengers like cAMP to terminate a signal. By
inhibiting this enzyme, certain drugs can prolong intracellular effects of neurotransmitters.
5. A drug that binds to a receptor and activates it to produce a maximum biological response is known as
a:
A. Partial agonist
B. Antagonist
C. Full agonist
D. Inverse agonist
ANSWER: C
Rationale: A full agonist binds to the receptor and mimics the endogenous neurotransmitter to produce
the maximum possible effect.
, 6. How many half-lives does it typically take for a medication to reach steady-state plasma
concentrations?
A. 1 to 2
B. 2 to 3
C. 4 to 5
D. 8 to 10
ANSWER: C
Rationale: It typically takes about 4 to 5 half-lives for a drug to reach steady state, where the rate of
administration equals the rate of elimination.
7. The 'therapeutic index' of a drug is a measure of which of the following?
A. The rate of drug absorption
B. The ratio between the toxic dose and the effective dose
C. The time it takes for half of the drug to be eliminated
D. The affinity of a drug for its receptor
ANSWER: B
Rationale: The therapeutic index is the ratio of the dose that produces toxicity to the dose that produces
a clinically desired effect; a narrow index requires close monitoring.
