Question 1 of 5
A client with cirrhosis of the liver becomes comatose and is started on neomycin 300 mg q6h via nasogastric tube. The rationale for this therapy is to:
Correct Answer: C
Rationale: Neomycin is an antibiotic, but this is not the rationale for administering it to a client in hepatic coma. Diuretics and salt-free albumin are used to promote diuresis in clients with cirrhosis of the liver. Neomycin destroys the bacteria in the intestines. It is the bacteria in the bowel that break down protein into ammonia. Lactulose is administered to create an acid environment in the bowel. Ammonia leaves the blood and migrates to this acidic environment where it is trapped and excreted.

Correct Answer: B
Rationale: Obtaining vital signs is important after connecting the client to the monitor because vital signs should be stable before the client is discharged from the emergency room. All are important, but the first priority is to monitor the client's rhythm. If the client is in severe pain, pain medication should be given after connecting him to the monitor and obtaining vital signs. Completion of the history profile is the least important of the nursing actions.
