A nurse is caring for a client who has a potassium deficiency. Which of the following foods should the nurse recommend as the best source of potassium?

Choice A reason: The client with an ileostomy is at risk for fluid volume deficit because an ileostomy is a surgical opening in the ileum, the last part of the small intestine, that allows the drainage of intestinal contents. This can result in a loss of fluids and electrolytes, especially sodium and potassium, which can lead to dehydration and hypovolemia.

Choice B reason: The client with cirrhosis is not at risk for fluid volume deficit, but rather fluid volume excess. Cirrhosis is a chronic liver disease that causes scarring and impaired liver function. This can lead to portal hypertension, which is an increase in the pressure in the portal vein that carries blood from the digestive organs to the liver. Portal hypertension can cause ascites, which is the accumulation of fluid in the abdominal cavity, and edema, which is the swelling of the tissues due to fluid retention.

Choice C reason: The client with heart failure is not at risk for fluid volume deficit, but rather fluid volume excess. Heart failure is a condition where the heart is unable to pump enough blood to meet the body's needs. This can lead to congestion of the blood vessels, which can cause pulmonary edema, which is the accumulation of fluid in the lungs, and peripheral edema, which is the swelling of the extremities due to fluid retention.

Choice D reason: The client with decreased renal function is not at risk for fluid volume deficit, but rather fluid volume excess. Decreased renal function is a condition where the kidneys are unable to filter the blood and remove excess fluids and wastes. This can lead to oliguria, which is a decrease in urine output, and anuria, which is the absence of urine output. This can cause fluid overload, which can affect the heart and the lungs.

Choice A reason: This is incorrect because amino acids are electrolytes. Electrolytes are substances that dissociate into ions when dissolved in water and conduct electricity. Amino acids have both positive and negative charges and can form ions in solution.

Choice B reason: This is incorrect because magnesium is an electrolyte. Magnesium is a metal that forms positive ions (cations) when dissolved in water. Magnesium is important for muscle and nerve function, as well as bone health.

Choice C reason: This is incorrect because phosphates are electrolytes. Phosphates are compounds that contain the phosphate ion (PO4 3-), which is a negative ion (anion) in solution. Phosphates are involved in energy metabolism, acid-base balance, and bone formation.

Choice D reason: This is correct because glucose is a nonelectrolyte. Nonelectrolytes are substances that do not dissociate into ions when dissolved in water and do not conduct electricity. Glucose is a simple sugar that dissolves as a whole molecule in water. Glucose is the main source of energy for the body.
