What substance do Kayexalate enemas primarily help to excrete?

• A. Sodium
• B. Potassium
• C. Calcium
• D. Magnesium

Answer: (B)

Kayexalate enemas primarily help to excrete potassium. Kayexalate, also known as sodium polystyrene sulfonate, is a medication that is used to treat hyperkalemia, which is an elevated level of potassium in the blood. When administered, Kayexalate binds to potassium in the gastrointestinal tract, allowing it to be expelled from the body through the stool. This mechanism is particularly beneficial in patients with conditions that lead to high potassium levels, such as chronic kidney disease, where the kidneys are unable to effectively filter and excrete potassium. By facilitating the removal of excess potassium, Kayexalate helps prevent potential complications associated with hyperkalemia, such as cardiac arrhythmias, which can be life-threatening. Other substances listed, such as sodium, calcium, and magnesium, are not the primary targets of Kayexalate therapy. While the medication may indirectly affect these electrolytes, its specific role is centered around managing potassium levels effectively.
