A nurse is teaching nutritional strategies to a client who has a low calcium level and an allergy to milk. Which of the following statements by the client indicates an understanding of the teaching?

The correct answer is c. I will eat foods high in potassium because the diuretics cause potassium loss.

Rationale for Choice A:

• Statement:"I should weigh myself daily and report any sudden weight loss or gain."
• Rationale:This statement is correct.It's crucial for patients with SIADH to monitor their weight daily as even slight fluctuations can signal fluid imbalances.Sudden weight gain can indicate fluid retention,while sudden weight loss might suggest dehydration.Both scenarios warrant medical attention.

Rationale for Choice B:

• Statement:"I need to limit my fluid intake to no more than 1 quart of liquids a day."
• Rationale:This statement is also correct.Fluid restriction is a cornerstone of SIADH management.By limiting fluid intake,patients can help prevent the buildup of excess fluid in the body,which can lead to complications such as hyponatremia (low sodium levels in the blood) and edema.

Rationale for Choice C:

• Statement:"I will eat foods high in potassium because the diuretics cause potassium loss."
• Rationale:This statement is incorrect.While some diuretics used in the treatment of SIADH can indeed cause potassium loss,this is not a universal side effect.Furthermore,increasing potassium intake without medical supervision can be dangerous,potentially leading to hyperkalemia (high potassium levels in the blood).It's essential for patients to consult with their healthcare providers for individualized guidance on potassium intake.

Rationale for Choice D:

• Statement:"I need to shop for foods that are low in sodium and avoid adding salt to foods."
• Rationale:This statement is correct.A low-sodium diet is often recommended for patients with SIADH to help manage fluid balance and prevent hyponatremia.Restricting sodium intake can reduce fluid retention and help maintain appropriate sodium levels in the blood.

Furosemide is a loop diuretic that works by blocking the reabsorption of sodium and chloride in the ascending loop of Henle in the kidney, leading to increased urine output. However, this medication can also cause potassium loss through increased urinary excretion, which can lead to hypokalemia (low potassium level). Hypokalemia can cause confusion, weakness, and other neurological symptoms.

The normal range for serum potassium is 3.5 to 5.0 mEq/L. A potassium level of 2.9 mEq/L is below the normal range and is considered hypokalemic. Therefore, the nurse should correlate the client's confusion with the low potassium level and notify the healthcare provider to adjust the medication or provide potassium supplements if indicated.
