Q

What are the functions of the liver?

A

CHO (glucose
Lipids
In charge (“bouncer” it detoxes Rx, etc)
Protein (breaks into amino acids, ammonia levels increased if not functioning properly)

Bile (half to 1 liter a day, aids in digestion)
Albumin (helps with oncotic pressure, w/o it you get edema, ascites)
Clotting (liver will have increased INR with liver dysfunction)
Kupffer cells (WBC’s specific to liver, they prevent infection)

If you CLIP it, it will grow BACK!

Q

What are the four liver diseases and what are they?

A

Cirrhosis - scarring of the liver tissue, hepatocyctes die

Non Alcoholic Fatty Liver Disease (NAFLD) - fatty liver from being obese, diabetic

Cholecystitis - Gallstones

Pancreatitis - Inflamed pancreas

The latter 3 can result in Cirrhosis

Q

What are the diagnostic lab testing/results of liver disease?

A

Liver Biopsy:

  • Afterwards lay PT onto right side to prevent liver contents from leaking into body cavity
  • Assess PT, if elevated BP after procedure notify MD

Clotting:
-Prolonged bleeding, thrombocytopenia, high INR

Chemistry:

  • High osmolarity
  • High bilirubin

CBC:
-Anemia

Liver function tests (LFT):
-Elevated AST,ALT, (normal is 35-45, over 45 is an issue)

Q

Describe TIPS.

A

Trans-Jugular Intra-Hepatic Portal Shunt

Through jugular vein though IVC and stick a stent into portal vein to lower portal hypertension and decrease narrowing and back-up which will prevent esophageal varicies.

Q

Describe Splenorenal shunt.

A

Diverts fluid spleen into kidney

Sx of splenic vein that’s removed and put onto the left renal vein to decrease the amount of blood flow to the portal vein so there’s less back-up.

Q

IV fluids

Blood Products

Q

What is spontaneous bacterial peritonitis, describe the symptoms, and how is it treated?

A

Issue from ascites:

Q

Due to the coagulation defects from liver disease, especially cirrhosis, what do you want to assess? What is decreased?

A
  • Decreased absorption of fat soluble vitamins

A
  • Reoccurring attacks
  • Weight loss
  • Urine color
  • Jaundice
  • Steatorrhea
  • Increase amylase
  • Xray shows calcification is the pancreas indicating necrosis

What are Cullen’s sign and Grey turners sign?

A

Blush color at umbilicus (Cullen’s sign)

Grey flanks (Grey turners sign)

42
Q

What liver tests indicate liver failure and what do they have to be over?

A

AST/ALT > 45

43
Q

What is an indication of bleeding in severe cirrhosis?

A

Increased albumin levels

RBC are broken and absorbed as protein

44
Q

What is a paracentesis?

A

Draining of fluid from abdomen

45
Q

What is a complication the nurse needs to monitor for regarding a paracentesis?
