A client with acute kidney injury (AKI) has a significantly decreased glomerular filtration rate (GFR). Which of the following is the primary indication for initiating dialysis in this client?

A) This statement is incorrect. While administering an antibiotic may be necessary if peritonitis is confirmed, it should not be done without obtaining a sample for testing first.

B) This statement is incorrect. Measuring vital signs and assessing for pain are essential aspects of client assessment, but they may not provide enough information to determine the cause of the cloudy drainage.

C) This statement is incorrect. Clamping the catheter may be necessary if peritonitis is suspected, but it should not be done without first obtaining a sample of the drainage for testing.

D) This statement is accurate. Cloudy drainage from the catheter site may indicate peritonitis, which is an infection of the peritoneal cavity. Obtaining a sample of the drainage for culture and sensitivity testing can help identify the presence of infection and guide appropriate treatment.

A. Incorrect. Administering a calcium channel blocker is not the first-line intervention for muscle cramps during dialysis.

B. Incorrect. Slowing down the blood flow rate during dialysis may be necessary in some cases, but it is not the first action to address muscle cramps.

C. Correct. Muscle cramps during dialysis can be caused by electrolyte imbalances, such as low potassium levels. Offering the client a sports drink with electrolytes can help alleviate the cramps.

D. Incorrect. Applying a heating pad to the affected muscles is not recommended during dialysis, as it may cause burns or worsen the cramps.
