week 7 Flashcards
(132 cards)
liver and its associated structures, including the gallbladder, bile ducts, and pancreas.
- These organs play a crucial role in digestion and metabolism.
Hepatobiliary
large, complex organ located in the upper right quadrant of the abdomen.
Functions:
- Filtering blood: The liver removes toxins and waste products from the blood.
- Producing bile: Bile is a fluid that helps to break down fats in the small intestine.
- Storing glucose: The liver stores excess glucose as glycogen.
- Synthesizing proteins: The liver produces many proteins, including albumin and clotting factors.
liver
is a small, pear-shaped organ located beneath the liver.
Functions:
- It stores bile produced by the liver.
- When food enters the small intestine, the ___ contracts and releases bile into the duodenum, where it helps to break down fats.
The gallbladder
________ are a network of tubes that carry bile from the liver and gallbladder to the small intestine.
The bile ducts
is a gland located behind the stomach.
Functions:
- It produces digestive enzymes that help to break down carbohydrates, proteins, and fats
- produces insulin, a hormone that helps to regulate blood sugar levels
The pancreas
- detects tumors, cysts, and stones
- conducive gel used
- NPO 8 hours before (b/c food causes gallbladder to contract and alters results)
abdominal ultrasound
MRI vs CT
____________
- Allows for exposure at different depths
- With or without use of oral and IV contrast medium – accentuates density differences
- If using IV contrast –
o Assess renal function – BUN and Cr labs
o Assess iodine and shellfish allergy
o Warn about “flushed feeling” with IV contrast admin
o Force fluids afterwards
______________
- Noninvasive
- Radiofrequency waves and magnetic field
- Detects disease, lesions, sources of GI bleed
- With or without IV contrast – gadolinium
- Contraindicated for
o Person with metal implants
o Pregnant person
CT
MRI
If using IV contrast –
o Assess renal function – BUN and Cr labs
o Assess iodine and shellfish allergy
o Warn about “flushed feeling” with IV contrast admin
o NPO 8 hours
o Force fluids afterwards
o Assess renal function – BUN and Cr labs
o Assess iodine and shellfish allergy
o Warn about “flushed feeling” with IV contrast admin
Xo NPO 8 hours
o Force fluids afterwards
remember IV contrast and kidneys!
________________
- Indicated if diagnosis of cholecystitis (gallstones) remains uncertain FOLLOWING an ultrasound
- ________ is a nuclear medicine study
- Nuclear medicine is what is injected IV
- Nuclear medicine is taken up by hepatocytes and excrete into bile
- A series of images are created to show the flow of bile from your liver to your gallbladder and then into your small intestine.
- Demonstrates patency of common bile duct and ampulla
HIDA scan – hepatobiliary scintigraphy
HIDA scan Demonstrates patency of common bile duct and ampulla
o The common bile duct is a tube that carries bile from the _____ and _____ to the _____________
o The ampulla is a small opening in the ___________, the first part of the small intestine. The common bile duct and the pancreatic duct join together at the ampulla.
o The common bile duct is a tube that carries bile from the liver and gallbladder to the small intestine.
o The ampulla is a small opening in the duodenum, the first part of the small intestine. The common bile duct and the pancreatic duct join together at the ampulla.
- visualizes and accesses the pancreatic, hepatic, and common bile ducts
- the endoscope is inserted through the mouth and advanced into the duodenum, the first part of the small intestine.
- The contrast dye is then injected into the common bile duct, which flows retrograde (backward) towards the liver and gallbladder.
ERCP - Endoscopic retrograde Cholangiopancreatography
ERCP - Endoscopic retrograde Cholangiopancreatography
Pre-procedure
- NPO 8 hours
- Consent form signed
- Admin sedation
Post-procedure
- Check vitals – looking for signs of ________- or __________
- ___________– most common complication
- Check for return of gag reflex
perforation or infection
pancreatitis
- Percutaneous procedure
- Needle inserted at ICS on right side where liver is located
- Aspirate to obtain hepatic tissue
- Ultrasound/CT guidance used concurrently sometimes
- Liver is very vascular
Liver biopsy
liver biopsy
Pre-procedure
- Check ________
- Make sure patient’s blood is _________
- Consent form signed
- Baseline vitals
- Explain – hold breath after ________ when need is inserted
Pre-procedure
- Check coags
- Make sure patient’s blood is typed and cross matched
- Consent form signed
- Baseline vitals
- Explain – hold breath after expiration when need is inserted
liver biopsy
Post-procedure
- Frequent vitals – looking for signs of internal bleeding =
increased HR #1
increased RR
BP decreased (later)
- Keep on _______ side for 2 hours
- HOB _______ for 12-24 hours
- Assess for complications – pneumothorax, peritonitis, shock
Post-procedure
- Frequent vitals – looking for signs of internal bleeding =
increased HR #1,
increased RR,
BP decreased (later)
- Keep on right side for 2 hours – the side of the liver/effected side b/c we want to put pressure on the liver to prevent bleeding
- HOB flat for 12-24 hours
- Assess for complications – pneumothorax, peritonitis, shock
Liver enzymes – ALT, AST, Alk Phos
elevated levels good or bad?
which one is specific to liver?
which 2 are not specific to liver?
Liver enzymes – ALT, AST, Alk Phos
Elevated = liver disease
ALT – specific to liver
AST and Alk Phos – not specific to liver
Liver enzymes – (3)
ALT, AST, Alk Phos
Serum Bilirubin
Elevated = _______ disease
Bilirubin – the product of RBC breakdown
Total bilirubin = conjugated/direct bilirubin + unconjugated/indirect bilirubin
liver
Conjugated/direct bilirubin vs Unconjugated/indirect bilirubin
________________
- Bilirubin that made it to the liver
- Water soluble
- Can be found in urine
- Elevated levels associated with obstructive jaundice – can’t get out of the body normally (stool) b/c of obstruction so its peed out
_________________
- Bilirubin did not make it to the liver (has not been conjugated by the liver)
- Not water soluble
- Can’t be found in urine
- Elevated levels associated with hepatocellular and hemolytic conditions – issue with liver itself or prior to the liver
Conjugated/direct bilirubin
- Bilirubin that made it to the liver (has been conjugated by the liver)
Unconjugated/indirect bilirubin
- Bilirubin did not make it to the liver (has not been conjugated by the liver)
Elevated levels associated with obstructive jaundice – can’t get out of the body normally (stool) b/c of obstruction so its peed out
Conjugated/direct bilirubin vs Unconjugated/indirect bilirubin

Serum ammonium
Elevated = _____ disease
liver
Normally ammonia is converted to urea in liver
- So an increase would mean there is an issue (with the liver) and ammonia is building up, not being converted to urea
