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
Fever is not typically a sign of fluid overload. It’s more commonly associated with a transfusion reaction, which could indicate an immune response to the transfused blood.
Choice B rationale
Dyspnea, or difficulty breathing, can be a sign of fluid overload. When the body has too much fluid, it can put pressure on the lungs, making it harder to breathe.
Choice C rationale
Pruritus, or itching, is not typically a sign of fluid overload. It may be a sign of an allergic reaction to the transfusion.
Choice D rationale
Bradycardia, or a slow heart rate, is not typically a sign of fluid overload. In fact, tachycardia, or a fast heart rate, is more common as the heart works harder to pump the excess fluid.
Correct Answer is B
Explanation
Choice A rationale
Having a total cholesterol level below 200 mg/dL is generally considered healthy and does not increase stroke risk. High cholesterol can contribute to atherosclerosis, a condition that increases stroke risk.
Choice B rationale
Losing excess weight can indeed help decrease stroke risk. Obesity is a risk factor for several health conditions that increase stroke risk, including hypertension and diabetes.
Choice C rationale
Glucocorticoids are not typically prescribed to decrease stroke risk. In fact, long-term use of glucocorticoids can increase the risk of conditions such as hypertension and diabetes, which in turn can increase stroke risk.
Choice D rationale
An HbA1c level of 6 percent or less is generally considered good blood sugar control for people with diabetes. Good blood sugar control can help prevent complications of diabetes, including stroke.
