,Question 1
A nurse is participating in a clinical trial involving a new
medication. Which statement best describes the primary
purpose of a randomized controlled trial during drug
development?
A. To determine the medication's manufacturing cost
B. To compare the safety and effectiveness of the investigational
drug with a control intervention while minimizing bias
C. To monitor medication use after it has been available for
several decades
D. To establish the retail price before regulatory approval
Correct Answer: B
Rationale:
Randomized controlled trials are designed to evaluate the
safety and effectiveness of a new medication by comparing it
with a placebo or standard treatment while reducing bias
through random assignment. Option A is unrelated to clinical
efficacy evaluation. Option C describes long-term post-
marketing surveillance rather than preapproval testing. Option
D is a business consideration and not a scientific objective of
clinical trials.
Question 2
,A nurse reviews a medication order and notices that the
prescribed dose exceeds the usual recommended range. What
is the nurse's priority action?
A. Administer the medication as prescribed because the
provider ordered it
B. Withhold the medication permanently without notifying
anyone
C. Clarify the prescription with the prescribing provider before
administration
D. Ask another nurse to administer the medication
Correct Answer: C
Rationale:
The nurse's primary responsibility is to ensure medication
safety. Clarifying an unusually high dose helps prevent potential
medication errors while respecting the prescribing provider's
authority. Administering the medication without clarification
may harm the patient. Permanently withholding therapy
without communication may delay necessary treatment.
Delegating the decision to another nurse does not resolve the
safety concern.
Question 3
, A patient asks why two medications with different brand names
appear to contain the same active ingredient. Which response
by the nurse is most appropriate?
A. "Brand names always indicate different active ingredients."
B. "Different manufacturers may market the same active
ingredient under different brand names."
C. "Generic medications are less effective than brand-name
medications."
D. "Brand names determine how well the medication works."
Correct Answer: B
Rationale:
Multiple manufacturers may market medications with the same
active ingredient under different brand names, while generic
products contain the same active ingredient and must meet
regulatory standards for quality and bioequivalence. Options A,
C, and D are inaccurate and may contribute to patient
misunderstanding.
Question 4
A nurse is educating a patient about factors that influence
individual responses to medications. Which factor is most likely
to affect drug response?
A. Hair color
