,Question 1
A nurse is explaining why medications undergo multiple phases
of clinical research before becoming available for routine
patient care. Which statement best reflects the primary
purpose of these phases?
A. To determine whether the medication can be manufactured
at the lowest possible cost
B. To evaluate safety, effectiveness, appropriate dosing, and
potential adverse effects in progressively larger groups of
participants
C. To compare the medication only with older drugs that are no
longer used in practice
D. To ensure the medication is prescribed exclusively by
specialists
Correct Answer: B
Rationale:
Clinical research progresses through multiple phases to
evaluate a medication's safety, effectiveness, dosage range, and
adverse effects before widespread use. Each phase provides
additional evidence supporting regulatory decisions. Option A
focuses on manufacturing rather than patient safety. Option C is
incorrect because studies may compare placebo, standard
,therapy, or other treatments. Option D is unrelated to the goals
of clinical research.
Question 2
A patient asks why a newly prescribed medication includes
instructions to report unexpected symptoms after it has already
been approved. What is the nurse's best response?
A. Rare adverse effects may become apparent only after a
medication is used by large numbers of people.
B. Approved medications no longer require safety monitoring.
C. Medication approval guarantees that every possible adverse
effect has already been identified.
D. Reporting symptoms is necessary only if the medication is
experimental.
Correct Answer: A
Rationale:
Post-marketing surveillance helps identify rare or delayed
adverse effects that may not have been detected during clinical
trials. Continuous monitoring improves medication safety
throughout the drug's life cycle. Options B and C are incorrect
because safety monitoring continues after approval. Option D
incorrectly limits adverse-event reporting to investigational
drugs.
, Question 3
A nurse is reviewing a patient's medication profile before
administering a newly prescribed drug. Which action best
supports safe medication administration?
A. Administer the medication immediately to avoid delaying
therapy.
B. Verify allergies, current medications, and relevant medical
history before administration.
C. Ask another patient whether they experienced adverse
effects from the medication.
D. Omit assessment if the provider has already prescribed the
medication.
Correct Answer: B
Rationale:
Reviewing allergies, concurrent medications, and pertinent
health history helps identify contraindications, potential
interactions, and patient-specific risks before administration.
Option A may compromise safety. Option C is not a reliable
source of clinical information. Option D ignores the nurse's
responsibility for independent assessment.
