Question 1
A nurse is teaching a community health class about where
medications come from.
Which statement correctly describes a natural source of drugs?
A. “Insulin made entirely in a laboratory is a natural source.”
,B. “Many antibiotics were originally discovered from
microorganisms.”
C. “All natural drugs are safer than synthetic drugs.”
D. “Natural drugs do not require FDA approval.”
Correct Answer: B. “Many antibiotics were originally discovered
from microorganisms.”
Rationale
Many medications originate from natural sources such as
plants, animals, and microorganisms. Penicillin, for example,
was originally derived from a mold.
Why the Other Options Are Incorrect
A: Laboratory-manufactured insulin is considered a
synthetic/biotechnologic product.
C: Natural does not automatically mean safer.
D: Natural-source drugs still require regulatory oversight.
Learning Objective
Identify natural sources of drugs.

Question 2
A nursing student asks why a new medication must undergo
preclinical testing before human trials.
What is the best response?
A. “To determine the market price of the drug”
B. “To evaluate safety and biologic activity in laboratory and
animal studies”
C. “To compare the drug with generic products”
D. “To obtain insurance approval”
Correct Answer: B. “To evaluate safety and biologic activity in
laboratory and animal studies”
Rationale
Preclinical trials assess toxicity, pharmacologic effects, and
potential therapeutic activity before exposing humans to the
drug.
, Why the Other Options Are Incorrect
A: Pricing is not the purpose of preclinical testing.
C: Generic comparison occurs later.
D: Insurance approval is unrelated.
Learning Objective
Describe the purpose of preclinical trials.
