The nurse is administering medications to a patient that has elevated ammonia due to cirrhosis of the liver. What medication will the nurse give to detoxify ammonium and to act as an osmotic agent?
A) Spironolactone (Aldactone)
B) Cholestyramine (Questran)
C) Lactulose (Cephulac)
D) Kanamycin (Kantrex)
C
Feedback:
Lactulose (Cephulac) is administered to detoxify ammonium and to act as an osmotic agent, drawing water into the bowel, which causes diarrhea in some clients. Potassium-sparing diuretics such as spironolactone (Aldactone) are used to treat ascites. Cholestyramine (Questran) is a bile acid sequestrant and reduces pruritus. Kanamycin (Kantrex) decreases intestinal bacteria and decreases ammonia but does not act as an osmotic agent.
