A nurse is reviewing the laboratory data of a client who has acute pancreatitis. The nurse should expect to find an elevation of which of following values?

Choice A rationale Amylase and lipase are the two primary pancreatic enzymes that become significantly elevated in the serum during acute pancreatitis. Damage to the pancreatic acinar cells allows these enzymes to leak into the bloodstream; a serum amylase level greater than 3 to 6 times the upper limit of normal (normal range 30-220 U/L) is a key diagnostic indicator. Choice B rationale Magnesium levels are often decreased, or hypomagnesemia (normal range 1.7-2.2 mg/dL), in acute pancreatitis due to various factors including malnutrition, malabsorption, or increased renal excretion, not elevated. Magnesium levels are not typically increased in this condition. Choice C rationale While the red blood cell count (normal range for males 4.7-6.1 million/mm³ and females 4.2-5.4 million/mm³) may appear falsely elevated due to hemoconcentration from fluid loss, a true elevation is not a primary or defining feature of acute pancreatitis; typically, it is unchanged or may be decreased with bleeding. Choice D rationale Hypocalcemia, or a decreased serum calcium level (normal range 9.0-10.5 mg/dL), is a common and serious complication of acute pancreatitis. This drop is due to the process of fat saponification, where circulating calcium binds to the fatty acids released by lipolysis in the injured pancreas.
