A nursing student says, “Modern drugs have always been
,made in laboratories.” The instructor asks for a correction
that reflects the history of pharmacology. Which response is
best?
Options
A. “Most early medications came from natural sources such
as plants, animals, and minerals.”
B. “Early medications were usually synthetic because natural
products were too weak.”
C. “Pharmacology began only after tablets and capsules were
invented.”
D. “Medication development started with antibiotics in the
1900s.”
Correct Answer
A
Rationales
A. Correct. Many of the earliest medications were
obtained from natural sources, including plants, animals, and
minerals. This reflects the historical development of
pharmacology before modern laboratory synthesis.
B. Incorrect. Early medications were not synthetic; many
were discovered from natural substances. Synthetic drug
production came later in pharmacologic history.
C. Incorrect. Pharmacology predates tablets and
capsules by centuries. Early drug use began long before
modern dosage forms existed.
D. Incorrect. Antibiotics were an important later
,development, but pharmacology did not begin with them.
The field has a much longer history.
Teaching Point
Early medications were often discovered from natural
sources.

A client asks why nurses still study older medicines like
digoxin and morphine. The nurse explains that some
important medications were discovered from natural
substances and later refined. Which example best reflects
this history?
Options
A. Digitalis was originally derived from foxglove plants.
B. Insulin was the first medication ever discovered.
C. All medicines were first created as brand-name products.
D. Pharmacology history began with intravenous therapy.
, Correct Answer
A
Rationales
A. Correct. Digitalis originated from foxglove, a plant
source, and is a classic example of a medication discovered
from nature and later developed for clinical use.
B. Incorrect. Insulin is historically important, but it was
not the first medication discovered. Pharmacologic
development occurred long before insulin.
C. Incorrect. Brand names are commercial labels, not the
origin of medication discovery. Many early medications
existed before modern branding.
D. Incorrect. Intravenous therapy is a route of
administration, not the beginning of pharmacology history.
Teaching Point
Many important drugs began as natural substances later
adapted for clinical use.
