A nurse in a provider’s office is talking with a patient who takes oxybutynin. The patient asks why he does not urinate as often.
Which of the following information should the nurse include about the action of oxybutynin?
The medication prevents the bladder muscles from involuntarily contracting.
The medication blocks the nervous system impulse to produce urine.
The medication reduces the rate at which the kidneys filter waste.
The medication decreases the sensitivity of the urethral sphincter.
The Correct Answer is A
Choice A rationale
Oxybutynin works by relaxing the muscles in the bladder. This helps decrease muscle spasms and improve the ability to control urination, thereby reducing the frequency of urination.
Therefore, this choice is correct.
Choice B rationale
Oxybutynin does not block the nervous system impulse to produce urine. It works primarily by relaxing the bladder muscles. Therefore, this choice is incorrect.
Choice C rationale
Oxybutynin does not reduce the rate at which the kidneys filter waste. Its primary action is on the bladder muscles. Therefore, this choice is incorrect.
Choice D rationale
Oxybutynin does not decrease the sensitivity of the urethral sphincter. Its main effect is to relax the bladder muscles. Therefore, this choice is incorrect.

Correct Answer is B
Explanation
Choice A rationale
Encouraging fluids with meals is not the best choice for a client who has HIV. While hydration is important, drinking fluids with meals can fill the stomach and decrease the client’s appetite, potentially leading to inadequate nutrient intake.
Choice B rationale
Offering small, frequent meals is a recommended intervention for a client who has HIV. This approach can help to maximize nutrient intake and manage symptoms such as nausea and early satiety. This is the correct choice.
Choice C rationale
While fresh fruits and vegetables are generally part of a healthy diet, they may not be appropriate for all clients with HIV. Some individuals may have difficulty digesting these foods, and others may be at risk of infection from uncooked produce.
Choice D rationale
Providing a diet of pureed foods is not a standard intervention for clients with HIV. This approach may be necessary for individuals with certain conditions or symptoms, but it is not applicable to all clients with HIV23.
Correct Answer is D
Explanation
Choice A rationale
Bulging skin around the stoma can be a sign of a hernia, but it’s not uncommon in the early postoperative period. It should be monitored, but it’s not typically a cause for immediate concern.
Choice B rationale
A stoma that protrudes 2 cm (0.8 in) above the abdominal wall is considered normal. The stoma should protrude above the skin to prevent stool from coming into contact with the skin, which can cause irritation and breakdown.
Choice C rationale
A stoma that is moist and beefy red is a sign of a healthy stoma. This indicates that the stoma has a good blood supply and is not ischemic or necrotic.
Choice D rationale
No fecal output from the stoma 24 hours after surgery could indicate a blockage or other complication and should be reported to the provider immediately.
