How do you take pancreatic enzymes

1 hr to immediately before eating

Three major hepatic themes and issues PROTEIN

1. Protein Comes from liver and food Amino acids break down food and release nitrogen Normally liver converts nitrogen into urea and the kidneys excrete it When liver fails, it does not convert nitrogen to urea and nitrogen accumulates Remember, protein ( albumin) creates colloid osmotic pressure to keep fluid in the blood vessels. So if protein is decreased, fluid will leak out of the vessels into cavities and tissues causing things like ascites, pleural effusions, and third spacing

Pain starts how long after eating during pancreatitis

24-48 hrs

A nurse is admitting a patient with cirrhosis. Which of the following prescriptions should the nurse anticipate? A. Obtain the clients PT and INR measurements B.

ETOH use ( Lennecs) Chronic viral infections Hep B,C,D Autoimmune hepatitis Steatohepatitis (fatty liver disease from chronic inlammation Meds/toxins/infection Chronic biliary issues ( bile duct obstruction, fibrosis) Cardiac cirrhosis (due to decreased perfusion)

Grey turners sign

Ecchymoses on flanks

Pancreatic LABS Erythrocyte sedimentation rate

Elevated

Gastroesophageal bleeding

Enlarged esophageal vessels develop from increased portal HTN Varices burst causing hematemesis and GI bleed Blood vessels become fragile due to ammonia and this makes blood vessels burst more easily Small bleeds may be able to be controlled but larger bleeds could be lethal

Patho of cirrhosis

Extensive scarring of liver from injury or chronic condition Normal tissue replaced with fibrotic tissue which does not function Portal areas affected most and decreased blood flow through liver occurs Liver enlarges and jaundice results

Pancreatic LABS Serum Glucose

Increased due to a decrease in insulin production

Pancreatic LABS WBC

Increased due to infection

Three major hepatic themes and issues AMMONIA

Increased nitrogen in blood combines with hydrogen to form ammonia Ammonia causes neurological changes such as agitation, confusion, lethargy, and eventually coma and death if not treated Ammonia also causes blood vessel walls to become fragile and brittle and can break easily with increased pressure (portal HTN) coughing, sneezing, dry heaving, and bending at the waist Treatment for elevated ammonia levels is lactulose --can be administered orally, via NGT, or by retention enema which. needs to be 30-60 minutes 2-3 BMS a day and increased mental status and decreased ammonia level is what you want to achieve

Pancreatic LABS Blood liver enzymes and bilirubin

Labs: Liver failure

Serum liver enzymes (LDH, ALT, AST) -Increased initially due to inflammation -ALT and AST will return to normal once the liver cells can no longer be inflammed ALP -Increased due to intrahepatic biliary obstruction Total bilirubin -Increased

How do you know if they arent getting enough pancreatic enzymes?

Steatorrhea and signs of T2DM

Late sign of pancreatitis

Tetany caused by hypocalcemia Calcium deposits in pancreatic tissues

Liver failure diagnostic tests

US - detects ascites, hepatomegaly, splenomegaly, biliary obstruction Abdominal x-ray and CT scan - detects ascites, hepatomegaly and splenomegaly MRI - detects masses Liver biopsy - fibrosis EGD - Detects esophageal varices, gastric and duodenal ulcers ERCP - view biliary tract, remove stones, and place stents if needed

Liver failure medications

Use opioids, sedatives, barbiturates with CAUTION and Sparingly best to avoid completely Beta blockers - help decrease esophageal bleeding by decreasing BP and vessel pressure Lactulose - binds to ammonia and it is excreted via stool - Dose to 2-3 stools per day - Check mental status for effectiveness Its working when mental status is improved and decreased or normal ammonia levels are obtained

Viral causes of Hepatitis

Varicella zoster, cytomegalovirus, herpes simplex

Three major hepatic themes and issues BLEEDING

When the liver fails, it does not produce Vitamin K and that leads to an increased PT/INR and thin blood You can get Vit K from green vegetables or you can administer it as a medication Old blood breaks down and released Nitrogen - so which can increase ammonia levels ---Administer saline enemas or perform gastric lavage to remove this old blood if the patient is internally bleeding

If you open a capsule of pancreatic enzymes for a patient to take what do you teach them

Wipe lips and swish water in mouth

Number one cause of chronic pancreatitis

alcoholism

Cardiovascular complications of pancreatitis

angina, hypotension

Autodigestion

caused by pancreatic digestive enzymes that activate prematurely before reaching intestines

Issues from auto-digestion of pancreas

* Micro emboli which leads to necrosis * Vasodilation - hypotension * Increase capillary permeability - hypotension that decreased blood flow to other organs * DIC * Hemorrhaging around pancreas

Physical assessment findings in Liver failure

Cognitive changes altered sleep pattern gastroesophageal bleed splenomegaly ascites jaundice petechiae, ecchymosis, epistaxis, hematemesis palmar erythema spider angiomas extremity and sacral edema asterixis Fetor hepaticus
