,Question 1
A nurse is teaching a community group about how medications
become available for patient use. Which statement by a
participant indicates an accurate understanding of the drug
development process?
A. "A medication is approved after laboratory testing alone if it
appears safe."
B. "Clinical trials help evaluate a medication's safety and
effectiveness before approval for general use."
C. "Once a medication is approved, it is no longer monitored for
safety."
D. "Animal studies provide enough evidence to determine the
correct dose for every patient."
Correct Answer: B
Rationale:
Clinical trials involving human participants are designed to
evaluate a medication's safety, effectiveness, appropriate
dosing, and adverse effects before regulatory approval.
Laboratory and animal testing are important early steps but are
insufficient for approval (Option A). Approved medications
continue to undergo post-marketing safety surveillance to
identify uncommon or delayed adverse effects (Option C).
,Animal studies cannot fully predict human dosing or responses
because of physiologic differences (Option D).
Question 2
A nurse is caring for a patient who asks why one prescribed
medication works well for a friend but not for them. Which
response by the nurse is most appropriate?
A. "All patients respond identically to the same medication."
B. "Medication effects may vary because of individual
differences such as age, genetics, health conditions, and other
medications."
C. "The medication is probably defective."
D. "The prescribed dose is always too low if symptoms
continue."
Correct Answer: B
Rationale:
Drug responses vary among individuals because of factors
including genetics, age, organ function, disease states, body
composition, and concurrent medications. Option A is incorrect
because individual variability is common. Option C incorrectly
assumes a manufacturing problem. Option D is inappropriate
because poor response may result from many factors besides
dosage.
, Question 3
A nurse administers an analgesic to a patient experiencing
postoperative pain. Which outcome best demonstrates the
medication's therapeutic effect?
A. The patient's pain score decreases from 8/10 to 3/10.
B. The patient develops mild nausea.
C. The patient's blood pressure decreases slightly without
symptoms.
D. The patient becomes drowsy for several hours.
Correct Answer: A
Rationale:
A therapeutic effect is the intended beneficial clinical outcome
of a medication. Reduced pain demonstrates the desired effect.
Nausea (Option B) and drowsiness (Option D) are adverse
effects that may accompany therapy. A mild decrease in blood
pressure (Option C) is not the primary therapeutic goal of an
analgesic.
Question 4
Before administering a newly prescribed medication, which
nursing action best supports medication safety?
A. Administer the medication immediately to avoid delaying
treatment.
