Pharmacology on NCLEX Questions
Extract:
Question 1 of 5
The client is to receive 3,000 mg of medication daily in a divided dose every eight (8) hours. The medication comes 500 mg per tablet. How many tablets will the nurse administer at each dose?
Correct Answer: 2
Rationale: Daily dose: 3,000 mg / 3 doses (every 8 hr) = 1,000 mg/dose. Tablets: 1,000 mg / 500 mg/tablet = 2 tablets per dose.
Question 2 of 5
The client with osteoarthritis is prescribed a nonsteroidal anti-inflammatory drug (NSAID). Which intervention should the nurse implement?
Correct Answer: A
Rationale: NSAIDs with meals reduce GI irritation, a common side effect. Striae, fever, or lab monitoring are less immediate concerns.
Question 3 of 5
The client diagnosed with migraine headaches is prescribed propranolol (Inderal), a beta blocker, for prophylaxis. Which information should the nurse teach the client?
Correct Answer: B
Rationale: Propranolol can cause bradycardia; teaching pulse monitoring ensures safety. It’s prophylactic, not acute, and dry mouth or lighting are unrelated.
Question 4 of 5
The client is complaining of low-back pain and is prescribed the muscle relaxant carisoprodol (Soma). Which teaching intervention has priority?
Correct Answer: C
Rationale: Carisoprodol causes drowsiness, a safety risk (e.g., falls, driving); warning is the priority. GI distress, tapering, or alcohol are secondary.
Question 5 of 5
The client is diagnosed with essential hypertension and is receiving a calcium channel blocker. Which assessment data would warrant the nurse holding the client's medication?
Correct Answer: D
Rationale: Dizziness on standing suggests orthostatic hypotension, a calcium channel blocker side effect, warranting holding the dose to prevent falls. Fever, cough, or BP are less critical.
