Quizplus · Accepted Answer

Patients with chronic kidney disease stage 5 often have hyperkalemia, which can lead to various complications including arrhythmias and cardiac arrest. The high potassium levels stimulate the secretion of aldosterone by the adrenal glands, which can contribute to the accumulation of potassium in the body. Therefore, a potassium restriction is necessary to prevent further complications. High potassium levels stimulate the secretion of aldosterone by the adrenal glands, which causes retention of sodium and water and leads to hypertension and edema. In patients with chronic kidney disease, the kidneys cannot excrete excess potassium, leading to hyperkalemia. Restricting potassium intake can help prevent hyperkalemia in these patients.
