Question 1
,A nurse is preparing to administer a medication by the oral
route. Which factor most directly influences how quickly the
medication begins to produce a therapeutic effect?
A. The color of the tablet
B. The rate at which the drug is absorbed into the bloodstream
C. The patient's eye color
D. The manufacturer of the medication label
Correct Answer: B
Rationale:
Drug absorption determines how rapidly a medication enters
systemic circulation and becomes available to produce its
therapeutic effect. Factors such as gastrointestinal blood flow,
gastric emptying, and dosage form affect absorption. Tablet
color and label manufacturer have no influence on onset of
action, and eye color is unrelated to pharmacokinetics.
Question 2
A nurse is reinforcing medication teaching with a patient who
has been prescribed an antibiotic. Which patient statement
demonstrates an understanding of the importance of
medication adherence?
A. "I will stop taking the medication when I feel better."
,B. "I will take the medication only if my symptoms become
severe."
C. "I will complete the entire prescribed course, even if I feel
well."
D. "I will save the remaining tablets for future illnesses."
Correct Answer: C
Rationale:
Completing the full course of prescribed therapy helps
eradicate infection, reduces the risk of recurrence, and
minimizes antimicrobial resistance. Stopping early, taking
medication only when symptoms worsen, or saving leftover
medication can contribute to treatment failure and
inappropriate medication use.
Question 3
A patient reports taking an over-the-counter herbal supplement
while also receiving prescription medications. What is the
nurse's priority action?
A. Advise the patient to discontinue all herbal supplements
immediately.
B. Document the supplement use and assess for possible drug
interactions.
, C. Tell the patient herbal products are always safe because they
are natural.
D. Recommend doubling prescription doses if herbs are taken.
Correct Answer: B
Rationale:
Many herbal products interact with prescription medications
and may alter drug metabolism or increase adverse effects. The
nurse should document supplement use, assess for interactions,
and notify the healthcare provider when appropriate. Natural
products are not inherently safe, and medication doses should
never be adjusted without provider direction.
Question 4
Before administering a scheduled medication, the nurse verifies
the patient's identity using two approved identifiers. What is
the primary purpose of this action?
A. To reduce medication administration errors
B. To improve medication absorption
C. To shorten hospital stay
D. To decrease medication costs
Correct Answer: A
