A nurse in a provider's office is talking with a client who takes oxybutynin. The client asks why he does not urinate as often. Which of the following information should the nurse include about the action of oxybutynin?
The medication reduces the rate at which the kidneys filter waste.
The medication decreases the sensitivity of the urethral sphincter.
The medication prevents the bladder muscles from involuntarily contracting.
The medication blocks the nervous system impulse to produce urine.
The Correct Answer is C
A. The medication reduces the rate at which the kidneys filter waste: This is incorrect as oxybutynin does not affect kidney function or the rate at which kidneys filter waste.
B. The medication decreases the sensitivity of the urethral sphincter: This is incorrect because oxybutynin primarily affects bladder muscle contraction, not the sensitivity of the urethral sphincter.
C. The medication prevents the bladder muscles from involuntarily contracting: This is correct as oxybutynin is an anticholinergic medication that reduces involuntary bladder contractions, leading to less frequent urination.
D. The medication blocks the nervous system impulse to produce urine: This is incorrect because oxybutynin works by blocking the action of acetylcholine in the bladder, not by blocking impulses to produce urine.

Correct Answer is C
Explanation
A. "Knee-high stockings can be rolled down slightly to provide comfort": Rolling down antiembolic stockings can cause bunching and reduce their effectiveness in preventing deep vein thrombosis. They should fit smoothly without rolling.
B. "I should flex my toes when applying the stockings": To apply the stockings, the toes should be pointed or relaxed, not flexed, to ensure proper application and avoid discomfort.
C. "The thigh-high stockings should reach just above the gluteal folds": This is correct as thigh-high stockings should extend to just above the gluteal folds to ensure proper fit and effectiveness in preventing blood clots.
D. "I should reapply the stockings before I get out of bed": Antiembolic stockings are typically applied in the morning after getting out of bed and should remain on throughout the day. Reapplying before getting out of bed is not necessary.
Correct Answer is D
Explanation
A. Offer meals to the client following physical activity: This is incorrect as eating after physical activity might be challenging for a client with dysphagia, and it is better to provide meals when the client is at rest.
B. Provide peanut butter on crackers as a snack choice: This is incorrect because peanut butter and crackers might be difficult to swallow and could pose a choking risk for someone with dysphagia.
C. Provide liquids in a cup with a straw: This is incorrect as straws can cause liquids to be aspirated more easily, which is a risk for clients with dysphagia.
D. Instruct the client to tilt his head forward when swallowing: This is correct because tilting the head forward can help prevent aspiration and facilitate safer swallowing in clients with dysphagia.
