and urine
- If it can't be excreted it builds up in the skin, mucous membranes, and brain
Jaundicing - correct answer. - Yellowing of the skin and mucus membranes
- Caused by: increased breakdown of RBCs, blockage of bile duct, and hepatic failure
0.0-1.5 - correct answer. - Total bilirubin level
Cirrhosis - correct answer. - Scarring to the liver and decreased liver function due to
chronic liver disease
Stage 1 - correct answer. What stage of alcoholic liver failure can be totally reversed if
ETOH abuse stops?
S/S Stage 1 Fatty Liver Disease - correct answer. - Enlargement of liver
(hepatomegaly)
- Jaundice r/t decreased ability to process bilirubin

S/S Stage 2 Alcoholic Hepatitis - correct answer. - Liver decreases in size as nodule
