Q

Liver excretes-

A

Approximately 500 to 1000 mL/day. Most (95%) of the bile that has entered the intestines is reabsorbed in the last part of the small intestine (terminal ileum), and returned to the liver for reuse

Q

Composition of bile

A
  • Water
  • Conjugated billirubin
  • Organic and inorganic ions
  • Small amount of proteins
  • 3 lipids (bile salts, lecithin, & cholesterol
  • These three must remain intact and balanced or the cholesterol will precipitate and form cholesterol gall stones*

  • No recurrent attacks of chlecystitis or cholelithiasis
27
Q

Nursing Interventions/Health Promotion

A

  • Chronic chol: when to seek care
  • Early detection
28
Q

Acute Interventions:

A
  • Treat pain, N/V
  • Comfort and emotional support
  • Fluid and electrolyte balance
  • Pruritis with jaundice: baking soda or alpha keri baths, lotions, soft old linen, temp control, short nails
  • Assess progression of symptoms & development of complications
29
Q

Nursing Care Post Laparoscopic Cholecystectomy

A
  • Pain management from phrenic nerve irritation from carbon dioxide.
  • Monitor for complications
  • Left side-lying Sims position
  • Deep breathing
  • Dressing over small incisions
  • Low fat diet
30
Q

Nursing Care: Open Cholecystectomy

A
  • Adequate ventilation and prevention of resp. complications
  • T Tube: maintain drainage to closed gravity system. Monitor drainage q 2 hrs. for first day post at q shift after.
  • NOTE** 500-1000 ml/day should decrease with healing
  • Protect surrounding skin: bile irritation
  • Monitor stool- may be clay colored but should regain pigmentation as bilirubin returns to the duodenum
  • Low fat diet
31
Q

Disorders of the Pancreas

A
  • Pancreatitis

* Pancreatic cancer

32
Q

Exocrine Functions of Pancreas

A
  • Acid must quickly and efficiently neutralize to prevent damage to the duodenal mucosa
  • Macromolecular nutrients- proteins, fats and starch- must be broken down much further before their constituents can be absorbed through the mucosa into blood.
33
Q

Pancreatic juice

A

digestive enzymes and bicarbonate

34
Q

Digestive enzymes

A

Trypsinogen and Chymotrypsin (protein digestions, Amylase (starch digestion), Lipase (fat digestion)

35
Q

Pancreas is innervated by the

A

vagus nerve, which applies a low level stimulus to secretion in response to anticipation of a meal.

  • **However the most important stimuli for pancreatic secretion comes from three hormones:
  • Cholecystokinin
  • Secretin
  • Gastrin
36
Q

Acute Pancreatitis:

A

Inflammation in the gland as a result of obstruction of the outflow of pancreatic secretions

37
Q

Etiology of acute pancreatitis

A
  • Biliary tract disease
  • Alcoholism
  • Trauma
  • Viral infections
  • Certain drugs
  • Neoplastic growth
  • Unknown
38
Q

Pathogenic mechanism of acute pancreatitis

A
  • Autodigestions of the pancreas
  • Obstruction of pancreatic ducts
  • Trypsinogen activated in the pancreas not in the duodenum
  • Elastase: Hemorrhage

39
Q

Involvement extends from

A

edematous pancreatitis to necrotizing pancreatits

40
Q

Interstitial Form:

A

is swollen and inflamed. Neither hemorrhage nor necrosis is present

41
Q

49
Q

Medication for acute pancreatitis:

A
  • No drug treatment to cure pancreatitis
  • Pain management: Opioids- morphine
  • G.I. motility- decrease vagal stimulation
  • Fluid and electrolyte replacement- monitor calcium and potassium loss
50
Q

Diet therapy for acute pancreatitis

A
  • NPO until abdominal pain subsides and amylase levels return to normal- rest the pancreas
  • TPN depending on situation
  • J tube feeding
  • Diet resumed no alcohol and caffeine low fat- bland diet- progress as tolerated
  • No alcohol
51
Q

Nursing diagnosis for acute pancreatitis

A
  • Acute pain
  • Imbalance nutrition
