Pharmacology on NCLEX Questions
Extract:
Question 1 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 2 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 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 nurse is administering an intramuscular (IM) injection to a client. When the nurse aspirates, there is a blood return. What is the most appropriate action for the nurse to take?
Correct Answer: C
Rationale: The nurse should not inject medication that has blood in it. Blood may interact with the medication and cause an adverse response.
Question 5 of 5
The nurse is teaching a parent how to administer oral iron supplements to a 2 year-old child. Which of the following interventions should be included in the teaching?
Correct Answer: B
Rationale: Give the medicine with orange juice and through a straw. Absorption of iron is facilitated in an environment rich in Vitamin C. Since liquid iron preparation will stain teeth, a straw is preferred.
