1. Why is the combination drug trimethoprim-sulfamethoxazole (TMP-SMX) necessary?

Correct answer: B

Rationale: The correct answer is B: To decrease bacterial resistance. Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination drug used to prevent bacterial resistance to sulfonamides. It works by targeting different steps in the bacterial metabolic pathway, making it harder for bacteria to develop resistance. Choice A is incorrect because the combination does not broaden the antibacterial spectrum; instead, it enhances effectiveness against specific bacteria. Choice C is incorrect as taste improvement is not the primary reason for combining these drugs. Choice D is incorrect because while combination therapy can sometimes help minimize toxic effects, the primary purpose in this case is to address bacterial resistance.

2. A nurse cares for adult clients who experience urge incontinence. For which client should the nurse plan a habit training program?

Correct answer: A

Rationale: For a bladder training program to succeed in a client with urge incontinence, the client must be alert, aware, and able to resist the urge to urinate. Habit training will work best for a confused client. This includes going to the bathroom (or being assisted to the bathroom) at set times. The other clients may benefit from other types of bladder training. A confused client may need structured assistance to establish a regular bathroom routine, which can help manage urge incontinence effectively. Clients with diabetes mellitus, kidney failure, or arthritis may require different strategies tailored to their specific conditions.

3. The client with chronic renal failure is being taught about fluid restrictions by the nurse. Which statement by the client indicates a need for further teaching?

Correct answer: C

Rationale: Choice C is the correct answer because clients with chronic renal failure should not skip dialysis sessions. Skipping dialysis can lead to serious complications and worsen the client's condition. It is crucial for clients to understand the importance of adhering to their dialysis schedule for optimal management of chronic renal failure. Choices A, B, and D are incorrect because they demonstrate understanding of fluid restrictions, the need to limit fluid intake to prevent overload, and the importance of medication compliance, respectively. These statements show appropriate knowledge and do not indicate a need for further teaching.

4. A client in the postanesthesia care unit has an as-needed prescription for ondansetron (Zofran). Which of the following occurrences would prompt the nurse to administer this medication to the client?

Correct answer: D

Rationale: The correct answer is D: Nausea and vomiting. Ondansetron is an antiemetic used to manage postoperative nausea and vomiting, as well as nausea and vomiting related to chemotherapy. It is not indicated for treating paralytic ileus, incisional pain, or urine retention. Paralytic ileus is a condition of the gastrointestinal tract characterized by the paralysis of intestinal muscles, which would not be treated with ondansetron. Incisional pain is typically managed with analgesics, not antiemetics. Urine retention is a urinary issue that does not involve nausea and vomiting, making ondansetron an inappropriate choice for this condition.

5. The nurse is monitoring a client who is receiving continuous ambulatory peritoneal dialysis. The nurse should notify the physician of which of the following findings?

Correct answer: B

Rationale: Cloudy dialysate outflow is an indication of peritonitis, a serious complication of peritoneal dialysis that requires immediate medical attention. Clear dialysate outflow is a normal finding indicating proper dialysis function and should not raise concern. Decreased urine output may be expected in a client undergoing dialysis due to the removal of excess fluids from the body. Increased blood pressure is a common complication in clients with kidney disease but is not directly related to cloudy dialysate outflow.
