RN HESI Pharmacology Exam Questions
Extract:
Question 1 of 5
The nurse is administering sevelamer during lunch to a client with chronic kidney disease (CKD). The client asks the nurse to bring the medication later. The nurse should describe which action of sevelamer as an explanation for taking it with meals?
Correct Answer: D
Rationale: Sevelamer binds dietary phosphorus in the gut, reducing absorption in CKD to prevent hyperphosphatemia. Taking with meals ensures binding. Reflux, acid buffering, and indigestion are unrelated.
Question 2 of 5
A client recently diagnosed with Parkinson's disease receives a new prescription for carbidopa-levodopa, a dopaminergic drug. To reduce the client's risk for injury, which instruction should the nurse provide?
Correct Answer: C
Rationale: Carbidopa-levodopa can cause orthostatic hypotension, increasing fall risk. Caution during position changes prevents dizziness or fainting. Beds, rugs (tripping hazard), or assistive devices are not universally needed.
Question 3 of 5
A client with myasthenia gravis receives a new prescription for pyridostigmine. Which information should the nurse obtain prior to administering the medication?
Correct Answer: D
Rationale: Pyridostigmine, a cholinesterase inhibitor, is best taken on an empty stomach to enhance absorption. Recent oral intake informs timing. Sleep, urination, and weight loss are unrelated to administration.
Question 4 of 5
A client with bipolar disorder admitted with severe depression and suicidal ideation receives a prescription for lithium carbonate. Which instruction should the nurse provide to the client?
Correct Answer: A
Rationale: NSAIDs increase lithium levels, risking toxicity (e.g., tremors, confusion). Eliminating NSAIDs is critical. Glucose, dental notifications, and iodine foods are unrelated to lithium safety.
Question 5 of 5
When administering zolpidem to an older client, which computer documentation indicates that the desired outcome has been achieved?
Correct Answer: A
Rationale: Zolpidem, a sedative-hypnotic, treats insomnia. Sleeping soundly indicates effectiveness. Incontinence, concentration, and outbursts are unrelated to zolpidem’s action.
