Pharmacology on NCLEX Questions
Extract:
Question 1 of 5
A 6-year-old child is seen in the emergency room after stepping on a rusty nail. He has received no immunizations. What should the nurse expect to give him immediately to prevent a tetanus infection?
Correct Answer: C
Rationale: Immune serum globulin provides immediate passive immunity against tetanus in an unimmunized child.
Question 2 of 5
The client in the intensive care department is receiving 2 mcg/kg/min of dopamine, an inotropic vasopressor. Which intervention should the nurse include in the plan of care?
Correct Answer: C
Rationale: Dopamine affects renal perfusion; hourly urine output via urometer monitors efficacy and prevents toxicity. BP, pulses, or light exposure are less critical.
Question 3 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 4 of 5
The nurse administers 18 units of Humulin N, an intermediate-acting insulin, at 1630. Which priority intervention should the nurse implement?
Correct Answer: B
Rationale: Humulin N peaks in 4–12 hours; evening meal prevents hypoglycemia during peak action. A1c, a.c. checks, or snacks are less immediate.
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.
