| Because Cirrhosis is not always known, alcoholism is by far the greatest factor leading to Cirrhosis. It is believed to result from the combination of | Alcohol's hepatotoxic effect on liver coupled with the common problem of protein malnutrition seen in alcoholics |
| Although liver cells have great potential for regeneration, repeated scarring decreases their | Ability to replace themselves |
| What do you assess before the procedure of Endoscopic for pancreatitis? | Prothrombin time and INR, tell pot that test takes a[[rpox 1-2 hrs during which time they must lie completely motionless on hard xray table which may be uncomfortable *Withhold food and fluids for 8 hrs before examination obtain pt's signature for consent * After, keep pt on NPO until gag reflex returns assess for abdominal pain tenderness and guarding which are signs of perforation |

| When can the liver not be able to regenerate its self? | When Cirrhosis is present *Overgrowth of new and fibrous tissue restricts flow of blood to the organ contributing to its destruction |
| ERCP | Endoscopic Retrograde Cholangiopancreatography enables visualization not only of biliary system but also of the pancreatic duct. *Test involves inserting a fiberoptic duodenoscope through oral pharynx through esophagus and then stomach into the duodenum |
| The ERCP of pancreas is a sensitive and reliable procedure for detecting what? | Significant degrees of pancreatic dysfunction *Can also be used to evaluate obstructive jaundice, remove common bile duct stones and place biliary and pancreatic duct stents to bypass obstruction |
| What indicates the presence of a tumor? | Localized pancreatic duct narrowing |
| Hepatitis D virus is carried by | Hepatitis B HBV |
| Which Hepatitis's are most common? | Hep A, B and C |
| Various of types of Hepatitis virus can be detected by what? | Antigen, antibody levels, and incubation periods |
| Notify lab of any antibiotics pt is currently taking because certain broad spectrum antibiotics such as | Neomycin can cause a decreased ammonia level giving inaccurate test results |
| What is the normal serum amylase test value? | 60-120 somogyi units/dL or 30 to220 units/L SI units |
| What is the normal serum ammonia test value? | 10 to 80 mcg/dL |
| How long does levels of amylase in urine remain elevated for? | 7 to 10 days after onset of pancreatitis |
| How can the biliary tract be evaluated safely accurately and noninvasively? | By intravenous IV injection of technetium and positioning patient under camera to record distribution of tracer in the liver biliary tree, gallbladder and proximal small bowel |
