Style Pharmacology Practice Questions with Answers and
Detailed Rationales
1.
A nurse is preparing to administer a medication but notices the dosage on the medication
label differs from the provider’s order. What is the nurse’s priority action?
Answer:
Do not administer the medication and verify the order with the provider.
Explanation: This tests the “right dose” and safety priority. Never assume or “fix”
discrepancies—always clarify before giving any medication.
2.
Which phase of pharmacokinetics describes how a drug moves from the bloodstream into
body tissues?
Answer:
Distribution
Explanation: Pharmacokinetics = ADME.
Absorption → entry into bloodstream
Distribution → movement to tissues (correct answer)
Metabolism → breakdown (liver)
Excretion → removal (kidneys)
3.
A patient asks why a medication must be taken at the same time each day. What is the
nurse’s best response?
Answer:
To maintain a consistent therapeutic drug level in the bloodstream.
Explanation: Timing prevents peaks/troughs and ensures effectiveness while avoiding
toxicity.
, 4.
Which factor most affects drug metabolism in older adults?
Answer:
Decreased liver function
Explanation: Aging reduces hepatic metabolism → drugs stay longer → higher toxicity risk.
5.
A nurse is administering an oral medication that should not be crushed. What is the priority
rationale?
Answer:
Crushing may alter drug absorption and increase risk of toxicity.
Explanation: Extended-release or enteric-coated meds depend on intact structure.
6.
Which route of administration provides the fastest drug absorption?
Answer:
Intravenous (IV)
Explanation: IV goes directly into bloodstream → immediate effect.
7.
A patient receiving opioids becomes difficult to arouse with slow respirations. What is the
nurse’s priority action?
Answer:
Hold the medication and assess respiratory status immediately.
Explanation: This is respiratory depression, a life-threatening opioid side effect.
8.
Which term describes the maximum response a drug can produce?
