Chapter 22: Problem 36

Kayexalate (sodium polystyrene sulfonate) has been ordered for a client with acute renal failure. To facilitate action of the medication, it is given with: A. Calcium gluconate B. Sorbitol C. Sodium bicarbonate D. Albumin

Short Answer

Expert verified
Answer: Sorbitol is given along with Kayexalate (sodium polystyrene sulfonate) to facilitate its action in a client with acute renal failure. Sorbitol acts as a cathartic (laxative), helping to move Kayexalate through the gastrointestinal tract, promoting the elimination of bound potassium in the feces. This combination of medications helps to lower potassium levels in the blood more effectively and quickly, which is crucial in the management of acute renal failure.

Step by step solution

01

Understanding the role of Kayexalate in acute renal failure

Kayexalate (sodium polystyrene sulfonate) is a medication used to treat high levels of potassium in the blood (hyperkalemia), which can occur in patients with acute renal failure. It is a cation-exchange resin that works by binding to potassium in the intestines, allowing it to be eliminated from the body in the feces.
02

Exploring the options provided

Now, let's briefly discuss each of the options provided: A. Calcium gluconate: This medication is used to treat low levels of calcium in the blood (hypocalcemia) or to counteract the effects of high levels of potassium on the heart. B. Sorbitol: This is a sugar substitute that has a laxative effect and is often used in combination with other medications to help them move through the gastrointestinal tract more quickly. C. Sodium bicarbonate: This is an alkalinizing agent that is used to treat metabolic acidosis and some forms of poisoning. D. Albumin: This is a protein found in blood plasma that helps to maintain fluid balance and transport substances throughout the body.
03

Identifying the correct substance

The correct substance to be given along with Kayexalate is Sorbitol (option B). Sorbitol acts as a cathartic (laxative), helping to move the Kayexalate through the gastrointestinal tract, promoting the elimination of bound potassium in the feces. This combination of medications helps to lower potassium levels in the blood more effectively and quickly, which is crucial in the management of acute renal failure.
04

Summary

In summary, Kayexalate (sodium polystyrene sulfonate) is administered with Sorbitol to facilitate its action in clients with acute renal failure. Sorbitol helps move the Kayexalate through the gastrointestinal tract, promoting the removal of excess potassium from the body.
