  • Presence of one or more calculi (gallstones) in the gallbladder
26
Q

Acute Cholecystitis

What diet should Pt. with gallbladder problems have ? and which medication is used for pain ?

A
  • Low fat
  • Morphine or Meperidine (Demerol)

If for pancreatitis answer Morphine
If for cholecsystitis or pancreatitis answer Demerol

29
Q

Cholecystography ( Gallbladder series ) Explain.
Prepping
Diet

A

Prepping Pt.

  • Explain
  • Check iodine allergies
  • If oral cholecystogram is to be done ( administer bilopaque or telepaque tablets as ordered
  • If IV cholecystogram is to be done the dye will be given just before exam in radiation department

Diet

  • Low fat meal in the evening before test
  • No further food after evening meal
  • Black coffee, tea, or water may be taken for breakfast
  • Give prescribed laxatives or enemas
30
Q

Post Cholecystography diet

A
  • Low fat
  • High protein
  • High calorie ( low calorie if overweight)
31
Q

Cholangiography

A
  • Endoscope study of biliary disorders to visualize bile ducts, presence of stones, strictures, or tumors or patency of common bile duct after surgery (Vit C after surgery)
32
Q

Percutaneous Transhepatic Cholangiography (PTC)
Explain procedure
(percutaneous meaning through the skin)

A
  • Dye injected through skin and abdominal wall into vessel or bile duct
  • X-ray liver and bile ducts
  • Thin needle is inserted through the skin below ribs and into the liver
  • Dye injected into liver and bile ducts and X-ray is taken
33
Q

What will you do if there is a blockage while doing a PTC ?

A
  • If there is a blockage, a thin flexible tube (stent) is left in liver to drain bile into the small intestines or collection bag outside the body
34
Q

Surgical cholangiography

A
  • Dye is inserted through a needle or catheter into common bile duct
35
Q

What must the nurse tell the Pt. Pre procedure

A
  • Explain procedure
  • CONSENT must be obtained
  • NPO night before the procedure
  • Administer laxative as prescribed
36
Q

Gallbladder Ultrasound

A
  • Determines the cause of upper abd pain ( RUQ)
  • Jaundice
  • Blockage of bile duct tubes leading from liver to gallbladder and duodenum and leakage of bile after surgery or an injury
  • No NPO/NO FULL BLADDER
37
Q

Cholecintigraphy or HIDA (Hydroxy Imino Diacetic Acid)

A
  • Study of gallbladder through imaging

- Indicates biliary obstruction ( gallbladder stone or cancer )

38
Q

HIDA Scan

A
  • Determines any blockage in the tubes (bile ducts) that lead from the liver to the gallbladder and small intestine ( duodenum )
  • Radio active tracer substance is injected into a vein in the arm
  • Liver removes the tracer from the bloodstream and adds it to the bile that normally flows through the bile ducts to the gallbladder
  • Gallbladder releases tracer into the beginning of the small intestine
  • Camera ( gamma ) takes pictures of the tracer as it moves through the liver, bile ducts, gallbladder, and small intestine
    If obstructed the radioactive tracer will not be able to reach the gallbladder coming from the liver
39
Q

Prep before procedure (HIDA SCAN)

A
  • Low fat diet night before

- NPO after midnight

40
Q

ERCP (Endoscopic Retrograde Cholangio Pancreatography )

A
  • x-ray ducts (tubes) that carry bile from liver to gallbladder and from gallbladder to small intestine using a fiberscope
  • Gallbladder cancer causes these ducts to narrow and block or slow flow of bile ( will cause jaundice )
41
Q

Where is the endoscope passed through ? (ERCP)

A
  • Passed through the mouth, esophagus, and stomach into the first part of the small intestine
  • Catheter is inserted through the endoscope into bile ducts
  • Dye injected through catheter into the ducts and x- ray taken
42
Q

What happens if there is an obstruction during an ERCP ? ( tumor blockage )

A
  • Fine tube is inserted into the duct to unblock it
  • Tube or stent may be left in place to keep the duct open
  • Tissue samples may also be taken
43
Q

Peritonoscopy

A
  • Direct visualization of peritoneum and liver (sometimes combined with liver biopsy, air sufflation may be used )
44
Q

Laparoscopic Cholecystectomy ( what is a helpful finding and how can you confirm diagnosis )

A
  • Murphy’s is useful in establishing diagnosis of cholecystitis
  • Confirmation of diagnosis depends on combination of physical finds ( palpation and ultrasound )
45
Q

Laparoscopic cholecystectomy ( Explain this procedure )

A
  • Carbon dioxide is insufflated into the abd during laparoscopic cholecystectomy
  • May irritate the diaphragm and cause referred shoulder pain (this complaint is common ) pain to right shoulder is common due to irritated nerve in diaphragm from the air insufflation of carbon dioxide
  • Pain in right shoulder lasts for 24-48 hours or may take several days
46
Q

Diabetes Mellitus (Type I )

47
Q

In type one what is not being metabolized ? and what is being used for energy ?
