ATI NUR 112 Fundamentals Exam Questions
Extract:
Question 1 of 5
A client with a history of anaphylactic reaction to penicillin receives a prescription for cephalexin 500 mg PO twice daily. Which action should the nurse take?
Correct Answer: A
Rationale: Due to potential cross-reactivity (1-4%) between penicillin and cephalosporins like cephalexin, contacting the provider prevents severe allergic reactions in a client with a penicillin anaphylaxis history.
Question 2 of 5
Ferrous sulfate elixir is prescribed for a client with iron deficiency anemia. Which instruction should the nurse provide this client about taking the liquid medication?
Correct Answer: A
Rationale: Using a straw minimizes tooth staining from ferrous sulfate. Diluting reduces GI irritation, antacids impair absorption, and milk’s calcium inhibits iron uptake.
Question 3 of 5
Based on a client’s serum digoxin level, the client is diagnosed with digoxin toxicity. Which action should the nurse expect to implement?
Correct Answer: C
Rationale: Digoxin toxicity requires checking electrolytes (e.g., hyperkalemia) and acid-base status to guide treatment. Potassium, cardioversion, or alternate routes are inappropriate.
Question 4 of 5
The nurse is providing discharge instructions for a client with metastatic cancer who is prescribed morphine for bone pain. Which information from the client indicates to the nurse an understanding of the medication?
Correct Answer: A
Rationale: Morphine causes constipation, so monitoring bowels and using stool softeners is critical. Grapefruit juice doesn’t affect morphine, benzodiazepines risk CNS depression, and agitation/insomnia are uncommon.
Question 5 of 5
Before administering a laxative to a bedfast client, it is most important for the nurse to perform which assessment?
Correct Answer: B
Rationale: Bowel movement frequency and consistency guide laxative need and dosing, preventing complications. Mobility, skin, and urge recognition are secondary.
