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
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.
Question 3 of 5
The nurse is teaching a client with type 1 diabetes mellitus (DM) about the onset, peak, and duration of a new prescription for glargine insulin. If the insulin is administered at 0800, when is the client most likely to experience hypoglycemia?
Correct Answer: B
Rationale: Glargine insulin has no pronounced peak, providing steady coverage for 24 hours, minimizing hypoglycemia risk at specific times. Midmorning, midafternoon, or midnight are not tied to glargine’s profile.
