A nurse is caring for a client who has progressing chronic kidney disease (CKD). Which of the following laboratory results would the nurse expect to find in the client's electronic health record?

The correct answer is choice C: "You will need to avoid rigorous exercise during the test."

Rationale:

• Choice A: The collection time for a 24-hour urine creatinine clearance test typically starts at a specific time, not necessarily with the first urine of the day.
• Choice B: A creatinine clearance test requires a 24-hour urine collection, not just 12 hours.
• Choice C: Avoiding rigorous exercise is important during the test as it can affect creatinine levels and impact the accuracy of the results.
• Choice D: Storing the urine container in a dark location is not necessary for a creatinine clearance test.

Choice A reason: Warming the dialysate in a microwave oven is not recommended because uneven heating could occur, leading to hot spots that can burn the peritoneal cavity. The dialysate should be warmed to body temperature using a warming device designed for this purpose.

Choice B reason: While some discomfort may be experienced during the first few exchanges, significant pain is not expected. If pain occurs, it should be reported to a healthcare provider, as it may indicate an underlying problem.

Choice C reason: Redness at the catheter exit site is not a normal expectation and could indicate an infection. The site should be kept clean and dry, and any signs of redness, swelling, or discharge should be reported to a healthcare provider immediately.

Choice D reason: There is no need to avoid foods high in fiber unless otherwise advised by a healthcare provider. In fact, a diet high in fiber can be beneficial for bowel regularity, which is important for patients on peritoneal dialysis.
