Aclient is being prepared to undergo laboratory and diagnostic testing to confirm the diagnosis of cirrhosis. which test would the nurse expect to be used to provide definitive confirmation of the disorder?

In confirming a diagnosis of cirrhosis, a disease which involves hepatocellular (liver cell) death replaced by scar tissue, the only true definitive diagnostic procedure is a liver biopsy.
However, when an invasive procedure as such is contraindicated, liver enzyme levels (LFTs) may be tested for in blood serum to estimate overall function (or lack thereof in vast cell death throughout the organ as seen in cirrhosis) of hepatocytes (liver cells). These enzymes include: alanine aminotransferase (ALT), aspartate aminotransferase (AST), and often gamma-glutamyl transferase (GGT). Also an abdominal ultrasound (US) of the right upper quadrant can determine the consistency of the liver, i.e. density of sanguinous living tissue versus dead scar tissue. Together, the serum enzyme levels and an US showing widespread hepatic scar tissue (indicative of cirrhosis) are enough to point to cirrhosis. However, true definitive evidence, as aforementioned, is only confirmed via US- or CT-guided tissue biopsy.
*note: CT stands for Computed Tomography, as in the old term "CAT-scan"

The freezing point of the ice is lowered because of the rock salt which then allows the ice to observe heat from the ice cream mixture without it melting.
