A client with chronic kidney disease (CKD) has a serum potassium level of 6.5 mEq/L. Which of the following medications removes excess potassium from the body?
Insulin and sodium bicarbonate
Calcium gluconate
atiromer (Veltassa)
Lisinopril
The Correct Answer is C
A. It helps to temporarily lower serum potassium levels by driving potassium into the cells. This effect is usually short-lived and is often used in emergency situations to quickly manage hyperkalemia.
B. Calcium Gluconate is used to stabilize the cardiac membrane in the setting of hyperkalemia, especially if there are ECG changes or symptoms of hyperkalemia. It does not lower the serum potassium level but helps protect the heart from the potential arrhythmias caused by elevated potassium levels.
C. Patiromer (Veltassa) is a potassium binder that helps to remove excess potassium from the body through the gastrointestinal tract. It binds potassium in the gut and facilitates its excretion in the stool.
D. Lisinopril is an ACE inhibitor used to treat hypertension and heart failure. It can actually increase potassium levels by decreasing the excretion of potassium through the kidneys.

C. Tolvaptan is used to slow the growth of kidney cysts in patients with PKD.
D. Hyponatremia is a common side effect of Tolvaptan due to increased water loss through urine. However, this is not the primary role.
