How is insulin used to treat hyperkalemia?
Insulin transports potassium from the blood to the cell along with glucose. Insulin binds to potassium to
... [Show More] remove it through the kidneys.
Insulin stimulates sodium to be removed from the cell in exchange for potassium.
Insulin breaks down the chemical components of potassium so that it is no longer effective. Insulin transports potassium from the blood to the cell along with glucose.

1. Which are causes of hypocalcemia?

Decreased resorption of calcium and phosphate from bone Repeated blood administration or pancreatitis
How does SIADH cause excess water?
The decrease in antidiuretic hormone increases serum glucose, which binds to water. The increase in antidiuretic hormone causes retention of water in the renal tubules.
The increase in antidiuretic hormone causes retention of sodium that retains excessive water in the renal tubules.
The decrease in antidiuretic hormone prevents the renal tubules from reabsorbing water. The increase in antidiuretic hormone causes retention of water in the renal tubules.
