Hyperkalemia is a potentially fatal condition found most often in patients on kidney dialysis, who have lost over 80% of their kidney function. The condition, which causes pain, severely erratic pulse, and tissue swelling throughout the body, stems from extremely high levels of potassium in the blood and, in an emergency, can be treated with an injection of calcium chloride. However, since calcium chloride destroys surrounding tissues if it escapes from a vein, doctors overwhelmingly prefer preventative treatments. Nonetheless, recipients of a donated kidney are not monitored for hyperkalemia after a successful kidney transplant.
If the statements above are all true, which of the following can properly be inferred on the basis of them?
(A) Most patients on kidney dialysis have high levels of potassium in their blood.
(B) Kidney failure is likely to cause severely erratic pulse and tissue swelling.
(C) The kidneys are at least partially responsible for maintaining adequate levels of calcium chloride in the blood.
(D) Patients who have lost 50% of their kidney function are not likely to develop hyperkalemia.
(E) Proper kidney function most likely involves the removal of excess potassium from the bloodstream.
