A Nurse Is Caring for a Patient with Chronic Renal

A nurse is caring for a patient with chronic renal failure. She asks the nurse why she can't use salt-substitutes in her diet. The nurse responds correctly if she said "Because…

A) …limiting salt substitutes in the diet prevents a buildup of waste products in the blood."
B) …salt substitutes contain potassium, which must be limited to prevent abnormal heartbeats."
C) …a substance in the salt substitute interferes with the transfer of fluid across capillary membranes, resulting in anasarca."
D) …a person's body tends to retain fluid when a salt substitute is included in the diet."
