Pharmacology on NCLEX Questions
Extract:
Question 1 of 5
The client with coronary artery disease is prescribed one (1) baby aspirin a day. Which instructions should the nurse provide the client concerning this medication?
Correct Answer: D
Rationale: Dark, tarry stools suggest GI bleeding, a serious aspirin side effect, requiring HCP notification. Empty stomach, Tylenol, or joint pain are less critical.
Question 2 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.
Question 3 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 4 of 5
A 68-year-old man has been diagnosed as having Parkinson's disease. He is started on Cogentin 0.5 mg PO daily. Which nursing action is most essential at this time?
Correct Answer: B
Rationale: Cogentin, an anticholinergic, causes dry mouth; encouraging cold beverages and hard candies helps manage this side effect.
Question 5 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.
