Frage 40
Frage
How are glucose and insulin used to treat hyperkalemia associated with acute renal failure?
Antworten
-
Glucose has an osmotic effect, which attracts water and sodium, resulting in more dilute blood and a lower potassium concentration.
-
When insulin transports glucose into the cell, it also carries potassium with it.
-
Potassium attaches to receptors on the cell membrane of glucose and is carried into the cell.
-
Increasing insulin causes ketoacidosis, which causes potassium to move into the cell in exchange for hydrogen.
