💊 Advanced Practice Questions
1. A client is prescribed metronidazole (Flagyl) for a dental abscess. Which instruction
should the nurse emphasize?
A. Avoid alcohol consumption
B. Take the medication with food
C. Monitor for hearing loss
D. Report any rash immediately
Correct Answer: A
Rationale: Metronidazole interacts with alcohol, causing a disulfiram-like reaction
(nausea, flushing, tachycardia). Patients must avoid alcohol during treatment and for 72
hours after.
, 2. A client with bipolar disorder is prescribed lithium. Which electrolyte imbalance
increases the risk of lithium toxicity?
A. Hypernatia
B. Hyponatremia
C. Hyperkalemia
D. Hypokalemia
Correct Answer: B
Rationale: Lithium is excreted via the kidneys and competes with sodium. Hyponatremia
increases lithium reabsorption, raising toxicity risk.
3. A nurse is administering morphine sulfate IV to a post-op client. Which assessment
finding should be reported immediately?
A. Respiratory rate of 10
B. Heart rate of 60
C. Blood pressure of 90/60
D. Oxygen saturation of 94%
Correct Answer: A
Rationale: Opioids can cause respiratory depression. A respiratory rate below 12 is
concerning and requires immediate intervention.
4. A client with a history of peptic ulcer disease is prescribed ketorolac (Toradol).
What is the nurse’s best action?
A. Administer the medication as ordered
B. Question the order due to GI risk
