200 Latest Q&A with Correct Answers
1. A nurse is teaching a client about a newly prescribed
medication. The client asks, "What does it mean that the
drug has a half-life of 12 hours?" Which response by the
nurse is most accurate?
A. "The medication will be completely eliminated from your body
in 12 hours."
B. "It takes 12 hours for the medication to reach its peak
effectiveness."
C. "It takes 12 hours for half of the medication to be eliminated
from your body."
D. "The medication will start working in 12 hours."
Rationale: Half-life is the time required for the body to eliminate
50% of a drug.
,2. A client is prescribed a medication that is highly protein-
bound. The nurse understands that which client condition
would most increase the risk of drug toxicity?
A. Hypertension
B. Hypoalbuminemia
C. Hyperglycemia
D. Hyperkalemia
Rationale: Hypoalbuminemia reduces protein-binding sites,
increasing free active drug.
3. The nurse is reviewing the concept of
pharmacodynamics with a nursing student. Which
statement best describes pharmacodynamics?
A. What the body does to the drug
B. The movement of drugs through the body
C. What the drug does to the body
D. The process of drug excretion
Rationale: Pharmacodynamics is the study of the biochemical
and physiologic effects of drugs on the body.
,4. A nurse is teaching a client about a newly prescribed
medication that has a narrow therapeutic index. Which
statement by the client indicates understanding?
A. "The medication has a wide margin of safety."
B. "I will need to have regular blood tests to monitor my
medication levels."
C. "I can take double the dose if I miss one dose."
D. "This medication works immediately after the first dose."
Rationale: A narrow therapeutic index requires regular
monitoring to prevent toxicity.
5. A client with severe liver disease is prescribed a
medication that is extensively metabolized by the liver. The
nurse expects the provider to:
A. Prescribe a higher dose
B. Prescribe a lower dose or a different medication
C. Administer the medication intravenously instead of orally
D. Discontinue all medications
, Rationale: Impaired liver metabolism leads to drug
accumulation and toxicity.
6. A patient is prescribed a medication that has a high first-
pass effect. Which route of administration would be MOST
appropriate to bypass this effect?
A. Oral
B. Intramuscular
C. Topical
D. Sublingual
Rationale: Sublingual administration bypasses the hepatic
portal system.
7. What are the "Five Rights" of medication administration?
A. Right Patient, Drug, Dose, Route, Time
B. Right Patient, Dose, Frequency, Route, Documentation
C. Right Drug, Dose, Route, Time, Refill
D. Right Patient, Drug, Dose, Route, Education
Rationale: The Five Rights are fundamental to medication
safety.
