Question 1
,A nurse is preparing to administer the first dose of an oral
antibiotic. Before giving the medication, which action is the
highest priority?
A. Assess the patient's history of drug allergies.
B. Ask the patient what they had for breakfast.
C. Measure the patient's weight.
D. Encourage the patient to drink extra water.
Correct Answer: A
Rationale:
Assessing for allergies is the priority because an allergic reaction
can occur with the first dose of a medication and may be life-
threatening. Although weight, food intake, and hydration may
influence medication therapy, identifying a potential allergy is
the most important safety measure before administration.
Question 2
A nurse explains to a patient that a medication is intended to
lower blood pressure by relaxing blood vessels. This explanation
describes the drug's:
A. Adverse effect
B. Therapeutic effect
,C. Toxic effect
D. Contraindication
Correct Answer: B
Rationale:
A therapeutic effect is the intended, beneficial action of a
medication. Adverse effects are unwanted responses, toxic
effects occur when drug levels become excessive, and
contraindications are conditions in which a medication should
not be used.
Question 3
A patient reports taking an over-the-counter cold medication
while also taking a newly prescribed prescription medication.
What is the nurse's best response?
A. "Over-the-counter medications are always safe to combine
with prescription drugs."
B. "Stop taking all over-the-counter medications immediately."
C. "Tell your healthcare provider about every medication,
vitamin, and herbal product you use."
D. "Only prescription medications can cause drug interactions."
Correct Answer: C
, Rationale:
Patients should report all medications, including over-the-
counter drugs, vitamins, and herbal supplements, because
these products may interact with prescription medications or
increase the risk of adverse effects. Nurses should encourage
communication rather than advising patients to stop
medications independently.
Question 4
A nurse administers an oral medication. Thirty minutes later,
the patient's pain decreases significantly. Which term best
describes this response?
A. Side effect
B. Toxic reaction
C. Therapeutic response
D. Drug incompatibility
Correct Answer: C
Rationale:
A therapeutic response is the desired clinical effect of a
medication. Side effects are secondary, often predictable effects
that may or may not be harmful. Toxic reactions result from
