Final answer:
Patients with cirrhosis who have elevated ammonia levels but no neurological symptoms should be given lactulose to lower the ammonia levels.
Step-by-step explanation:
Patients with cirrhosis who have an elevated level of ammonia but no neurological symptoms should be given lactulose to lower ammonia. Although the liver is normally free from ammonia, high ammonia levels in the blood can be toxic to the central nervous system. This condition, known as ammonia intoxication, can cause symptoms such as tremors, speech problems, and blurred vision. Lactulose helps remove ammonia from the blood and can be used as a treatment.
