Question 1
,A nurse is preparing to administer an oral medication to a
client. Which nursing action best helps ensure the medication
reaches its intended therapeutic effect?
A. Administer the medication at the prescribed time and dose.
B. Crush all tablets before administration.
C. Give the medication only when the client requests it.
D. Withhold the medication if the client reports mild nausea.
Correct Answer: A
Rationale:
Administering medications at the prescribed dose and
scheduled time helps maintain therapeutic drug concentrations
and maximize effectiveness. Not all tablets can be crushed
because some have special coatings or extended-release
formulations. Medications should not be given solely on client
request unless prescribed as needed (PRN), and mild nausea
alone does not automatically justify withholding medication
without further assessment.
Question 2
A nurse explains to a client that a prescribed medication will
lower blood pressure by relaxing blood vessels. The nurse is
describing the medication's:
,A. Adverse effect
B. Mechanism of action
C. Half-life
D. Toxic effect
Correct Answer: B
Rationale:
A mechanism of action describes how a medication produces its
therapeutic effect within the body. Adverse effects are
unintended reactions, half-life refers to the time required for
half the drug to be eliminated, and toxic effects occur when
drug levels become excessive.
Question 3
A client asks why laboratory tests are ordered while taking a
newly prescribed medication. Which response by the nurse is
most appropriate?
A. "The tests determine whether the medication is achieving
the desired effect safely."
B. "Laboratory tests are only needed if side effects occur."
C. "The tests determine whether you can stop taking the
medication."
, D. "Laboratory tests replace the need for physical assessments."
Correct Answer: A
Rationale:
Laboratory monitoring evaluates medication effectiveness,
detects adverse effects, and identifies organ dysfunction before
serious complications develop. Physical assessment and client-
reported symptoms remain essential components of monitoring
therapy.
Question 4
A nurse reviews a medication order that appears unusually high
compared with the recommended dosage. What is the nurse's
priority action?
A. Administer the medication because the provider prescribed
it.
B. Clarify the order before administering the medication.
C. Ask another nurse to administer the medication.
D. Reduce the dose without notifying the provider.
Correct Answer: B
Rationale:
The nurse has a professional responsibility to verify
questionable medication orders before administration.
