Question

What is the most common cause of hyperkalemia?
A) ​liver cirrhosis
B) ​inadequate excretion of potassium from renal failure
C) ​inadequate excretion of sodium from renal failure
D) ​high blood cholesterol levels
E) ​chronically low blood pressure

Quizplus · Accepted Answer

The most common cause of hyperkalemia is inadequate excretion of potassium from renal failure. This can lead to a buildup of potassium in the blood. Other causes include medications that interfere with potassium excretion, such as certain blood pressure medications, and cellular destruction or injury, such as with burns or trauma. Liver cirrhosis, high blood cholesterol levels, and chronically low blood pressure are not typically associated with hyperkalemia. Inadequate excretion of sodium can lead to hyponatremia, not hyperkalemia.
