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 D
Explanation
A. "You may drink full liquids until 6 hours before the procedure": Typically, clients are instructed to follow a clear liquid diet and to stop drinking any liquids a few hours before the procedure, not full liquids.
B. "You will lie on your right side for the procedure": The client usually lies on their left side during a colonoscopy, not the right side.
C. "You should warm the liquid bowel preparation before drinking it": Bowel preparation solutions are generally not warmed; they are consumed as directed, often chilled to make them more palatable.
D. "You will be moderately sedated during the procedure": This is correct as colonoscopy usually involves moderate sedation to ensure client comfort and tolerance during the procedure.
Correct Answer is A
Explanation
A. Increase the IV flow rate: This is correct as the client’s low blood pressure could indicate hypovolemia. Increasing the IV flow rate can help improve blood volume and blood pressure, addressing a potential cause of hypotension.
B. Cover the client with a warm blanket: While this could help if the client is hypothermic, it does not address the immediate issue of low blood pressure.
C. Compare the reading to the preoperative value: While this can provide context, it does not directly address the current low blood pressure situation.
D. Reassure the client: Reassuring the client is important but does not address the urgent issue of low blood pressure.
