Question 1
Clinical Scenario
,A nursing student asks the instructor why many medications
used in clinical practice are derived from plants rather than
being manufactured entirely in laboratories.
Question
Which statement by the instructor best explains a natural
source of drugs?
Options
A. Natural drugs are produced only through recombinant DNA
technology.
B. Natural drugs may be obtained from plants, animals,
minerals, or microorganisms.
C. Natural drugs are considered safer than synthetic
medications.
D. Natural drugs do not require FDA approval.
Correct Answer
B. Natural drugs may be obtained from plants, animals,
minerals, or microorganisms.
Rationale
Many medications originate from natural sources, including
plants (e.g., digitalis), animals (e.g., insulin historically),
,minerals, and microorganisms (e.g., antibiotics). These
substances may be used directly or modified chemically to
improve efficacy and safety. Natural origin does not guarantee
safety or eliminate regulatory requirements.
Why the Other Options Are Incorrect
A: Recombinant DNA technology produces synthetic or
biotechnology-derived drugs.
C: Natural products can produce serious adverse effects
and toxicity.
D: All marketed drugs require appropriate regulatory
approval.
Learning Objective
Identify major sources of drugs used in nursing practice.
