What causes hepatic encephalopathy?
- A. Buildup of ammonia in the body
- B. Buildup of urea in the body
- C. Fatty infiltration of the liver
- D. Jaundice
Correct Answer: A
Rationale: Hepatic encephalopathy is caused by the buildup of ammonia in the body. Ammonia, a byproduct of protein metabolism, normally gets converted to urea in the liver for excretion. However, in liver dysfunction, such as cirrhosis, the liver cannot effectively convert ammonia to urea, leading to its accumulation in the body and subsequently causing hepatic encephalopathy. Choices B, C, and D are incorrect as they do not directly relate to the pathophysiology of hepatic encephalopathy.

Which laboratory data indicate the client's pancreatitis is improving?
- A. The amylase and lipase serum levels are decreased
- B. The white blood cell count (WBC) is decreased
- C. The conjugated and unconjugated bilirubin levels are decreased
- D. The blood urea nitrogen (BUN) serum level is decreased
Correct Answer: A
Rationale: The correct answer is A. Amylase and lipase are specific markers for pancreatitis. A decrease in their serum levels indicates improvement in pancreatitis. Choice B, a decreased white blood cell count (WBC), is more indicative of an improvement in infection rather than pancreatitis. Choices C and D, decreased bilirubin levels and blood urea nitrogen (BUN) levels respectively, are not specific markers for pancreatitis improvement.
