Question 1
,A nurse is preparing to administer a medication that has been
prescribed by mouth. Which factor most directly influences how
quickly the medication begins to produce its effect?
A. The patient's eye color
B. The rate at which the drug is absorbed into the bloodstream
C. The patient's dominant hand
D. The medication's package size
Correct Answer: B
Rationale: The onset of drug action depends largely on how
rapidly the medication is absorbed into the bloodstream and
reaches its site of action. Factors such as dosage form, blood
flow, and gastrointestinal function can affect absorption.
Question 2
A patient asks why a medication is prescribed by the
intravenous (IV) route instead of by mouth during an
emergency. Which response by the nurse is most appropriate?
A. "IV medications are always safer than oral medications."
B. "IV medications are absorbed more quickly because they
enter the bloodstream directly."
C. "Oral medications cannot produce therapeutic effects."
D. "IV medications remain in the body longer."
Correct Answer: B
,Rationale: Intravenous administration bypasses the absorption
process and delivers the medication directly into the circulation,
resulting in rapid onset of action. This makes it the preferred
route during emergencies.
Question 3
A nurse is reviewing a medication order before administration.
Which action best promotes medication safety?
A. Administer the medication immediately without reviewing
the patient's allergies.
B. Verify the patient's identity using two approved identifiers.
C. Ask another patient to confirm the medication.
D. Skip reviewing the medication label if it was checked earlier.
Correct Answer: B
Rationale: Verifying patient identity with two approved
identifiers is a fundamental medication safety practice that
helps prevent administration errors. Allergy verification and
label checks are also essential before giving medications.
Question 4
A patient reports taking an herbal supplement in addition to
prescribed medications. What is the nurse's priority action?
, A. Advise the patient to stop all herbal products immediately.
B. Document the supplement use and assess for possible
interactions.
C. Ignore the information because herbal products are natural.
D. Delay all prescribed medications indefinitely.
Correct Answer: B
Rationale: Herbal supplements may interact with prescription
medications. The nurse should document their use, assess for
potential interactions, and notify the healthcare provider when
appropriate.
Question 5
A medication reaches the bloodstream and is transported
throughout the body. Which pharmacokinetic process is
occurring?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Correct Answer: B
Rationale: Distribution is the movement of a drug from the
bloodstream to body tissues and organs. This process
determines where the medication exerts its therapeutic effects.
