Therapeutics, 14th Edition
Chapter: “Drug Discovery: From Medicinal Plants to Computer-
Aided Drug Design”
Below are EXACTLY 20 exam-ready, nursing-focused MCQs,
tightly aligned to the language, concepts, and emphasis of this
,chapter. No external sources, clinical guidelines, or
assumptions are used.
1. Which historical observation most directly supports the role
of medicinal plants in early drug discovery?
A. Synthetic modification of lead compounds
B. Isolation of bioactive alkaloids from traditional remedies
C. Development of receptor-binding assays
D. Use of high-throughput screening platforms
Correct Answer: B
Rationale: Goodman & Gilman describes how many early
drugs originated from medicinal plants, with isolation of active
alkaloids (e.g., morphine, quinine) forming the foundation of
pharmacology.
Citation: Goodman & Gilman, 14th ed., Drug Discovery: From
Medicinal Plants to Computer-Aided Drug Design
2. In modern drug discovery, a “lead compound” is best
defined as:
A. A marketed drug with proven clinical efficacy
B. A compound with optimal pharmacokinetics
C. A chemical structure showing desirable biological activity
D. A compound approved by regulatory agencies
Correct Answer: C
,Rationale: The text defines a lead compound as a chemical
entity with biological activity that can be optimized through
chemical modification.
Citation: Goodman & Gilman, 14th ed., Drug Discovery: From
Medicinal Plants to Computer-Aided Drug Design
3. Which process is primarily responsible for improving
selectivity and potency during drug development?
A. Random screening
B. Lead optimization
C. Clinical trial enrollment
D. Post-marketing surveillance
Correct Answer: B
Rationale: Lead optimization involves systematic chemical
modification to enhance potency, selectivity, and
pharmacokinetic properties.
Citation: Goodman & Gilman, 14th ed., Drug Discovery: From
Medicinal Plants to Computer-Aided Drug Design
4. High-throughput screening (HTS) contributes to drug
discovery by:
A. Predicting adverse drug reactions
B. Testing drug metabolism in humans
, C. Rapidly evaluating large compound libraries
D. Replacing animal testing
Correct Answer: C
Rationale: Goodman & Gilman emphasizes HTS as a method to
rapidly screen thousands of compounds for biological activity
against a target.

Medicinal Plants to Computer-Aided Drug Design
5. Which technological advance most directly enabled
structure-based drug design?
A. Automated dispensing systems
B. X-ray crystallography of drug targets
C. Herbal pharmacopoeias
D. Phase I clinical trials
Correct Answer: B
Rationale: Structure-based drug design relies on knowledge of
the three-dimensional structure of drug targets, commonly
obtained through X-ray crystallography.
