,Question 1
A nurse is teaching a community group about the stages of drug
development. Which statement by a participant indicates
correct understanding?
A. A drug is marketed immediately after it shows activity in
laboratory testing.
B. Clinical trials are conducted to evaluate safety and
effectiveness in humans before widespread marketing.
C. Animal testing is performed only after a drug has been
approved for public use.
D. Drugs are approved solely on the basis of manufacturer
reports.
Correct Answer: B
Rationale:
Clinical trials evaluate safety, efficacy, dosage, and adverse
effects in human participants before regulatory approval.
Laboratory and animal studies occur before human testing.
Regulatory agencies independently review submitted evidence
rather than relying solely on manufacturer claims.
Question 2
A nurse reviews the medication history of a client enrolled in a
clinical drug trial. Which nursing action is the priority?
,A. Ensure informed consent has been obtained before study
participation.
B. Recommend increasing the study dose if symptoms persist.
C. Advise the client to stop reporting adverse effects until the
study ends.
D. Tell the client that withdrawal from the study is not
permitted.
Correct Answer: A
Rationale:
Ethical research requires voluntary informed consent before
participation. Nurses should not independently adjust study
medications. Participants should promptly report adverse
effects and retain the right to withdraw from research at any
time without penalty.
Question 3
A newly approved medication continues to be monitored after
reaching the market. What is the primary purpose of this post-
marketing surveillance?
A. Determine the medication's chemical structure.
B. Identify rare or long-term adverse effects not detected during
preapproval studies.
C. Replace all earlier clinical trial findings.
, D. Eliminate the need for healthcare providers to report adverse
events.
Correct Answer: B
Rationale:
Post-marketing surveillance helps identify uncommon or
delayed adverse events that may not appear in smaller
preapproval studies. It complements rather than replaces
clinical trials, and healthcare providers remain responsible for
reporting significant adverse events.
Question 4
A client asks why a generic medication was substituted for the
prescribed brand-name product. Which response by the nurse
is most appropriate?
A. "Generic drugs must contain different active ingredients."
B. "Generic drugs are expected to provide comparable
therapeutic effects while meeting quality standards."
C. "Generic drugs are less effective but less expensive."
D. "Generic drugs never produce adverse effects."
Correct Answer: B
