,Question 1
A nurse is explaining the purpose of the phases of clinical drug
testing to a client interested in participating in a research study.
Which statement by the nurse is most accurate?
A. Early-phase studies primarily determine whether a
medication is safe and identify appropriate dosage ranges.
B. Early-phase studies are designed to compare the new
medication with every available treatment.
C. Early-phase studies guarantee that a medication will be
approved for public use.
D. Early-phase studies eliminate the need for monitoring after
the medication reaches the market.
Correct Answer: A
Rationale:
Early-phase clinical studies focus on evaluating safety,
tolerability, pharmacokinetics, pharmacodynamics, and
appropriate dosage ranges in a limited number of participants
before larger efficacy studies are conducted. Option B is
incorrect because comparing a new drug with all existing
therapies is not the purpose of early-phase trials. Option C is
incorrect because successful early studies do not guarantee
regulatory approval. Option D is incorrect because ongoing
,monitoring continues after approval to identify uncommon or
delayed adverse effects.
Question 2
A client asks why a newly prescribed medication is available
only through a restricted distribution program. Which response
by the nurse is most appropriate?
A. "The program helps ensure the medication is used safely by
monitoring specific risks."
B. "The medication has never been tested in humans."
C. "The medication cannot cause adverse effects when used
correctly."
D. "The program prevents healthcare providers from reporting
side effects."
Correct Answer: A
Rationale:
Some medications with significant risks require additional safety
measures, such as restricted distribution programs, patient
education, laboratory monitoring, or prescriber certification to
reduce the likelihood of serious adverse outcomes. Option B is
incorrect because approved medications have undergone
clinical testing. Option C is incorrect because all medications
carry some risk of adverse effects. Option D is incorrect because
, adverse event reporting remains an important component of
medication safety.
Question 3
A nurse is reviewing a medication order and recognizes that the
prescribed drug has a narrow therapeutic range. Which nursing
action is the priority?
A. Monitor the client closely for therapeutic response and signs
of toxicity.
B. Administer double the prescribed dose if symptoms persist.
C. Skip laboratory monitoring because effectiveness is
predictable.
D. Delay administration until symptoms become severe.
Correct Answer: A
Rationale:
Medications with a narrow therapeutic range require careful
assessment, monitoring, and often laboratory evaluation to
maintain drug concentrations within a safe and effective range.
Option B increases the risk of toxicity. Option C ignores the
need for monitoring. Option D may delay needed therapy and
worsen the client's condition.
