A nurse is providing education to a client about the etiology of acute renal failure. Which statement by the client indicates a correct understanding of the condition?

A. Incorrect. Muscle cramps in acute renal failure are often related to electrolyte imbalances, including high potassium levels. Encouraging the consumption of potassium-rich foods would exacerbate the issue.

B. Incorrect. Muscle relaxants may not be appropriate for all clients, and the underlying cause of the muscle cramps should be addressed first.

C. Correct. Applying warm compresses to the affected muscles can help relax muscle tension and provide relief from muscle cramps.

D. Incorrect. Gentle stretching exercises may not be appropriate for a client experiencing muscle cramps, as stretching could exacerbate the discomfort.

A. Incorrect. Withholding food and drink for 24 hours is not necessary for a CT scan with contrast dye.

B. Correct. Before a CT scan with contrast dye, it is essential to assess the client for allergies, especially to iodine and shellfish. Contrast dyes used in CT scans contain iodine, and clients with allergies to iodine or shellfish may have an allergic reaction to the contrast dye.

C. Incorrect. While administering intravenous fluids may be beneficial in certain situations, it is not a specific precaution for a CT scan with contrast dye.

D. Incorrect. Removing jewelry and metallic objects is a standard precaution for all imaging procedures, but it is not specific to a CT scan with contrast dye.
