Question 1
,A nurse is preparing to administer a prescribed oral medication.
Which factor most directly influences the rate at which the drug
begins to produce its therapeutic effect?
A. The medication's color
B. The route of administration
C. The patient's blood type
D. The medication's manufacturer
Correct Answer: B
Rationale:
The route of administration significantly affects the onset of
drug action. Oral medications generally have a slower onset
than intravenous medications because they must be absorbed
through the gastrointestinal tract before entering systemic
circulation. Drug color, manufacturer, and blood type typically
do not directly affect onset of action.
Question 2
A patient asks why a medication must be taken exactly as
prescribed. Which response by the nurse is most appropriate?
A. "Taking extra doses will help the medication work faster."
B. "The prescribed schedule helps maintain therapeutic drug
levels."
,C. "Drug schedules are based only on hospital policy."
D. "Missing doses is acceptable if symptoms improve."
Correct Answer: B
Rationale:
Maintaining therapeutic drug levels helps ensure effectiveness
while minimizing toxicity. Taking extra doses can increase
adverse effects, and missing doses may reduce therapeutic
effectiveness. Medication schedules are based on
pharmacologic principles rather than hospital policy alone.
Question 3
A nurse is teaching a patient about adverse drug reactions.
Which statement indicates understanding?
A. "All side effects are life-threatening."
B. "Adverse reactions occur only when medications are given
incorrectly."
C. "Some adverse reactions can occur even when medications
are taken as prescribed."
D. "Adverse reactions happen only with injectable drugs."
Correct Answer: C
, Rationale:
Adverse drug reactions may occur despite correct
administration and appropriate dosing. They can range from
mild to severe and may occur with any route of administration.
Not all side effects are life-threatening, and adverse reactions
are not limited to medication errors.
Question 4
A patient receives an intravenous antibiotic. Which process
must occur before the medication can exert its effect on the
infection?
A. Distribution to the target tissues
B. Complete metabolism by the liver
C. Excretion by the kidneys
D. Elimination from the bloodstream
Correct Answer: A
Rationale:
After entering the bloodstream, the drug must be distributed to
the tissues where it is needed. Metabolism and excretion are
elimination processes that generally occur after the drug has
exerted its therapeutic effect.
