SECTION 1 — PHARMACOLOGICAL PRINCIPLES & MEDICATION SAFETY
Question 1
A nurse is reviewing pharmacokinetics with a client. Which process
describes the movement of a medication from the bloodstream into
body tissues?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Answer: B. Distribution
Rationale: Distribution occurs after absorption and describes how a
medication moves through the bloodstream into tissues and body
fluids. Metabolism primarily transforms medications, while excretion
removes them from the body.
Question 2
Which organ is primarily responsible for metabolizing most
medications?
,A. Heart
B. Liver
C. Spleen
D. Pancreas
Answer: B. Liver
Rationale: The liver contains enzymes that metabolize many
medications, often converting lipid-soluble drugs into forms that can be
eliminated. Impaired hepatic function can therefore increase
medication accumulation and toxicity.
Question 3
A nurse is caring for a client with severe renal impairment. Which
medication-related problem is the nurse most concerned about?
A. Increased drug excretion
B. Decreased drug absorption
C. Medication accumulation
D. Increased first-pass metabolism
Answer: C. Medication accumulation
Rationale: The kidneys eliminate many medications and metabolites.
Renal impairment can decrease clearance, causing medications to
accumulate and increasing the risk for toxicity.
Question 4
,A medication has a short half-life. Which statement best describes this
medication?
A. It remains in the body for a prolonged period.
B. It takes longer to reach peak concentration.
C. Its concentration decreases relatively quickly.
D. It cannot cause adverse effects.
Answer: C. Its concentration decreases relatively quickly.
Rationale: Half-life is the time required for the medication
concentration in the body to decrease by approximately 50%. A shorter
half-life generally means the drug is eliminated more rapidly.
Question 5
Which medication route generally produces the fastest systemic effect?
A. Oral
B. Subcutaneous
C. Intravenous
D. Topical
Answer: C. Intravenous
Rationale: IV medications enter the bloodstream directly and therefore
bypass absorption barriers associated with other routes. This produces
rapid onset and requires careful monitoring for adverse reactions.
Question 6
, A nurse receives a medication order that is difficult to read. What
should the nurse do?
A. Ask another nurse to interpret it.
B. Administer the most likely medication.
C. Clarify the order with the prescriber.
D. Document that the medication was refused.
Answer: C. Clarify the order with the prescriber.
Rationale: An unclear medication order creates a significant patient-
safety risk. The nurse should clarify the prescription before
administration rather than guessing or relying on another person's
interpretation.
Question 7
Which action best reduces medication errors?
A. Preparing medications for several clients at once
B. Comparing the medication with the prescription during
administration
C. Avoiding barcode scanning when busy
D. Asking the client to identify the medication
Answer: B. Comparing the medication with the prescription during
administration
Rationale: Medication verification should occur throughout the
administration process. Barcode technology, medication labels, and the
prescription should be checked according to facility policy.
