Pharmacology on NCLEX Questions
Extract:
Question 1 of 5
The client received Narcan, a narcotic antagonist, following a colonoscopy. Which action by the nurse has the highest priority?
Correct Answer: D
Rationale: Narcan reverses opioids but has a short half-life; frequent assessment (15–30 min) monitors for re-sedation or respiratory depression, the priority.
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
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 4 of 5
An adult is hospitalized for an acute attack of gout. Which medication should the nurse expect to administer?
Correct Answer: B
Rationale: Colchicine is used to treat acute gout attacks by reducing inflammation, unlike allopurinol, which prevents attacks.
Question 5 of 5
The client is receiving atropine, an anticholinergic, to minimize the side effects of routine medications. Which intervention will help the client tolerate this medication?
Correct Answer: C
Rationale: Atropine causes dry mouth; sugarless gum stimulates saliva, improving tolerance. Hypotension, diet, or exercises are unrelated.
