72
Q

Jaundice, and hemorrhage

73
Q

Pancreatitis

A

An inflammatory condition of the pancreas that may be acute or chronic.

76
Q

Pancreatitis: the level of lipase

A

Rises in 4 to 8 hrs, peaks at 24 hrs, and may remain elevated for 14 days. Amylase and lipase levels may be elevated to 5 to 40 times normal

78
Q

Pancreatitis: med surg interventions

A

Treatment is medical unless the precipitating cause is biliary tract disease, then surgery may be indicated. Food and fluids are withheld; NPO; NG tube is inserted. Parenteral anticholinergic medication, such as atropine or propantheline , helps decrease pancreatic activity

79
Q

Pancreatitis: diet

A

A clear liquid diet with gradual progression may be started once the pt’s pain is under control for at least 24 hrs. The diet must be free of alcohol and gastric stimulants, such as coffee. Low-fat, high-calorie, high-carb diet after discharge.

ERCP (the gold standard); CA 19-9 can be elevated in other diseases such as cancer of the gallbladder or in no malignant conditions such as acute and chronic pancreatitis, hepatitis, and biliary duct obstruction

86
Q

Pancreatic cancer: med-surg interventions

A

Cancer of the head of the pancreas is usually treated by pancreatoduodenectomy; the Whipple procedure involves resection of the Antrum of the stomach, the gallbladder, the duodenum, and varying amounts of the pancreas.
Combinations of drugs such as fluorouracil and gemcitabine may produce a better response than a single chemotherapeutic agent.

87
Q

a procedure in which fluid is withdrawn from the abd cavity. Done by either gravity or a vacuum. It is only a temporary method. Relieves ascites and also provides fluid for lab exam. Warning can go into shock from procedure

122
Q

Eliminating alcohol, hepatotoxins(Tylenol)
Well balanced diet high in calories (2500 to 3000 calories / day) moderately high in protein (75g of high quality protein), low in at and sodium ( 1000 to 2000 mg /day ) and with additional vitamins and folic acid will usually meet the needs of the pt and improve deficiencies

initially pt is on bed rest with accurate monitoring of I&O, Fluid restrictions are in place of 500 to 1000mL and sodium of 1000 to 2000 mg.
Diuretic therapy may be added and Spironolactone (aldactone) 300 to 1000 mg / day may be used to obtain the desired diuresis
Vitamin supplements and salt poor albumin my be administered to attempt to restore plasma volume

126
Q

Maintenance of oxygen content levels within the blood and administration of fresh frozen plasma and packed RBC’s, Vitamin K, histamine receptor blockers such as cimetidine (tagament) and electrolyte replacement. AVOID ammonia buildup with use of cathartics(lactulose)

130
Q

In the past a low protein diet

A

was often prescribed for patients with cirrhosis it was thought it would decrease the amount of ammonia in the intestine

131
Q

Lactulose decreases

A

The bowels pH from 7 to 5 thus decreasing the production of ammonia by bacteria within the bowel. Lactulose may be administered orally, retention enema, or via NG tube.
