问题单项选择题

What laboratory finding is the primary diagnostic indicator for pancreatitis ？（）

A．Elevated blood urea nitrogen (BUN).

B．Elevated serum lipase.

C．Elevated aspartate aminotransferase (AST).

D．Increased lactate dehydrogenase (LD).

答案

参考答案：B

解析：

Elevation of serum lipase is the most reliable indicator of pancreatitis because this enzyme is produced solely by the pancreas. A client's BUN is typically elevated in relation to renal dysfunction; the AST, in relation to liver dysfunction; and LD, in relation to damaged cardiac muscle.
