Pharmacology on NCLEX Questions
Extract:
Question 1 of 5
The client is admitted to the burn unit and prescribed pantoprazole (Protonix), a proton pump inhibitor (PPI). Which statement best supports the scientific rationale for administering this medication to a client with a severe burn?
Correct Answer: A
Rationale: Severe burns increase stress ulcer risk due to gastric acid hypersecretion; PPIs like pantoprazole prevent this. Infection, vasoconstriction, or skin growth are unrelated.
Question 2 of 5
The male client with a chronic urinary tract infection is prescribed trimethoprim-sulfamethoxazole (Bactrim). Which statement indicates the client needs more teaching?
Correct Answer: C
Rationale: Stopping Bactrim when symptoms resolve risks incomplete treatment and resistance; full course is needed. Hydration, duration, and diarrhea management are correct.
Question 3 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.
Question 4 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 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.
