TEST BANK
Question 1
Clinical Scenario
A nursing student is reviewing the development process for a
new investigational drug. The drug has successfully completed
,preclinical trials and is now being tested in a small group of
healthy volunteers to determine its safety profile, dosage range,
and pharmacokinetics.
Question
In which phase of drug evaluation is this investigational drug
currently being studied?
Options
A. Phase I
B. Phase II
C. Phase III
D. Phase IV
Correct Answer
A. Phase I
Rationale
Phase I studies are the first stage of testing in humans and
involve a small number of healthy volunteers (20-80). The
primary goal is to determine the drug's safety, safe dosage
range, and pharmacokinetic profile (how the drug is absorbed,
distributed, metabolized, and excreted).
Why the Other Options Are Incorrect
A. Phase I is correct as described.
B. Phase II studies involve a larger group of patients (100-300)
with the target disease to evaluate effectiveness and further
assess safety.
,C. Phase III studies involve large patient populations (1000-
3000) to confirm effectiveness, monitor adverse effects, and
compare the drug to standard treatments.
D. Phase IV studies are post-marketing surveillance trials that
occur after the drug has been approved by the FDA to monitor
for rare or long-term adverse effects.

Question 2
Clinical Scenario
A nurse is preparing to administer a medication to a patient
who is 8 weeks pregnant. The patient asks if the medication is
safe for her baby. The nurse reviews the drug label and notes it
, contains a category that indicates adequate and well-controlled
studies in pregnant women have failed to demonstrate a risk to
the fetus.
Question
Which FDA pregnancy safety category would the nurse identify
on the drug label?
Options
A. Category A
B. Category B
C. Category C
D. Category X
Correct Answer
A. Category A
Rationale
FDA Pregnancy Category A indicates that adequate and well-
controlled studies in pregnant women have failed to
demonstrate a risk to the fetus in the first trimester (and there
is no evidence of risk in later trimesters). This is the safest
category.
Why the Other Options Are Incorrect
A. Category A is correct.
B. Category B indicates animal studies show no risk, but there
are no adequate human studies, or animal studies show risk but
human studies do not.
