Which of the following is a diagnostic lab test for a client with pancreatitis?
Complete blood count (CBC)
AST/ALT
Blood glucose
Amylase and lipase levels
The Correct Answer is D
Rationale:
A. A CBC may show leukocytosis but is not diagnostic for pancreatitis.
B. AST/ALT may be elevated if biliary obstruction is present, but they are not specific for pancreatitis.
C. Blood glucose may rise in pancreatitis due to impaired insulin release, but it is not diagnostic.
D. Amylase and lipase levels are the primary diagnostic lab tests for acute pancreatitis, with lipase being more specific and remaining elevated longer.

Correct Answer is B
Explanation
Rationale:
A. Elevated AST indicates hepatocellular injury, but it does not directly reflect fluid volume status.
B. In liver cirrhosis, the liver produces less albumin, leading to reduced plasma oncotic pressure. Low albumin allows fluid to leak into interstitial spaces, causing ascites, edema, and overall fluid volume excess.
C. Prolonged PT reflects impaired clotting factor synthesis in cirrhosis, not fluid status.
D. High bilirubin indicates impaired bile excretion and liver dysfunction, but it is not a direct marker of fluid overload.
Correct Answer is C
Explanation
Rationale:
A. 59% dextrose in lactated Ringer’s is not a standard solution and would be hypertonic and unsafe.
B. 0.45% sodium chloride does not provide the glucose necessary to prevent hypoglycemia.
C. 10% dextrose in water (D10W) is correct. If TPN runs out, a dextrose-containing solution should be administered to prevent hypoglycemia until the next TPN bag is available.
D. Lactated Ringer’s does not provide sufficient glucose to maintain blood sugar during TPN interruption.
