Unit 1 Chapter 53 Cirrhosis Flashcards
What is Cirrhosis
progressive deterioration of liver condition and function and scarring of liver tissue and necrosis
- Causes increased resistance to portal blood flow.
What is the #1 sign of Cirrhosis?
Jaundice: yellowing of eyes and skin, indication of liver failure
-occurs when diseased liver does not remove enough
bilirubin from the blood. Jaundice causes yellowing of skin and
icterus (yellowing of eyes), and a darkening of the urine.
What is the function of the Liver?
- synthesis of bile salts
- synthesis of clotting factors
- vitamin storage (esp. fat soluble vitamins)
- detoxification of drugs & toxic substances * cleanses the blood
- converts glucose to glycogen & stores it
- forms urea to remove ammonia
*first pass occurs in liver
What occurs if there is a decrease in portal blood flow?
- no clotting factors: risk for hemmroage
-no storage of Fats or vitamins
-no cleaning of the blood
-no removal of ammonia: hepatic encaptholy , fector hepaticus: fruity musky breath due to build of waste products in blood
Risk factors for Cirrhosis
- Hepatitis * Alcohol * Biliary obstruction
What are the types of Cirrhosis
- Postnecrotic cirrhosis (caused by viral hepatitis [especially hepatitis C] and certain drugs or other toxins)
- Laennec’s or alcoholic cirrhosis (caused by chronic alcoholism)
- Biliary cirrhosis (also called cholestatic; caused by chronic biliary
obstruction or autoimmune disease)
s/s of cirrhosis
- Jaundice and icterus (yellow coloration of the eye sclerae)
- Dry skin
- Pruritus (itchy skin)
- Rashes
- Purpuric lesions, such as petechiae (round, pinpoint, red-purple hemorrhagic lesions) or ecchymoses (large purple, blue, or yellow bruises)
- Warm and bright red palms of the hands (palmar erythema)
- Vascular lesions with a red center and radiating branches, known as spider angiomas (also called telangiectases, spider nevi, or vascular spiders), on the nose, cheeks, upper thorax, and shoulders
- Ascites
*Splenomegaly - Peripheral dependent edema of the extremities and sacrum
- Vitamin deficiency (especially fat-soluble vitamins A, D, E, and K)
When performing an assessment of the abdomen, keep in mind that hepatomegaly (liver enlargement) occurs in many cases of early cirrhosis. Splenomegaly is common in nonalcoholic causes of cirrhosis. As the liver deteriorates, it may become hard and small. - Fetor hepaticus - musty or sweet breath odor. Fruity, musty smell caused by high levels of dimethyl sulphide * -Altered level of consciousness: due to increase of ammonia
*Asterixis
*Amenorrhea (no menstrual period) may occur in women, and
*men may exhibit testicular atrophy, *gynecomastia (enlarged breasts), and impotence as a result of inactive hormones.
Your patient with Cirrhosis is exhibiting flappy hands. What is the name of this clinical manifestation?
A. Asterexis
B. Fector Hepaticus
C.Ascites
D. Portal hyperion
A. Asterexis
Monitor for asterixis —a coarse tremor characterized by rapid, nonrhythmic extensions and flexions in the wrists and fingers (hand flapping).
Diagnostics and labs of Cirrhosis
Liver values
* AST, ALT, LDH
* Increased bilirubin
* Decreased albumin
* Protein studies
* Pigment studies (direct and indirect bilirubin)
* Ammonia levels
* Fat levels
* Prothrombin time; Hgb, Hct
* Prolonged PT/INR
* Decreased platelets
* X-rays
* MRI
* Ultrasound
* Liver biopsy
* EGD
* ERCP
Your patient with cirrhosis exhibits a odd musky breath. What is the manifestation of this?
A. kussmal
B. Fector hepaticus
C. diabetes keto acidosis
D. metabolic alkalosis
B. Fector hepaticus
What types of medications should you avoid for a patient with cIRRHOSIS?
-Tylenol
- liver toxic medications
Complications of Cirhosis
- Portal hypertension
- Ascites
*esophageal varices - Biliary obstruction
- Hepatic encephalopathy
*Thrombocytopenia
*DIC
What is Thrombocytopenia?
reduction of platlet count
-risk for bleeeding
Nursing intervention and considerations for Thrombocytopenia
*Monitor for petechia, ecchymosis,
bleeding of gums, occult or frank blood in stool, urine, or vomitus
* Institute bleeding precautions
* Minimize the risk of trauma
Bleeding Precautions
Use a soft toothbrush and do not use dental picks.
Avoid rectal suppositories, enemas, and thermometers.
Avoid vaginal douches and tampons.
*Avoid straining with bowel movements.**
avoid constipation
Avoid forceful coughing, sneezing, or blowing of the nose.
Use caution with sharp objects.
Use an electric razor instead of razor blades.

What is Portal Hypertension
Due to pressure building up in the
portal vein, pressure builds up in the liver and prior to the liver.Blood flow backs into the spleen, causing splenomegaly (spleen enlargement). Veins in the esophagus, stomach, intestines, abdomen, and rectum become dilated. Portal hypertension can result in ascites (excessive abdominal [peritoneal] fluid), esophageal varices (distended veins), prominent abdominal veins (caput medusae), and hemorrhoids.
What is Esophageal varicies
distention of veins in esophageal wall due to portal hypertension
Which of the following medications are used to prevent bleeding for a patient diagnosed with Esophageal varices?
A. atropine
B.Epinephrine
C. Propranolol
D. diltiazem
.C. Propranolol
A nonselective beta-blocking agent such as propranolol is usually prescribed to prevent bleeding. By decreasing heart rate and the hepatic venous pressure gradient, the chance of bleeding may be reduced.
Patient teaching for Portal hypertension and Esophageal varicies
hint- push
Avoid straining with bowel movements.
avoid dry hard foods
However, any activity that increases abdominal pressure may increase the likelihood of a variceal bleed, including heavy lifting or vigorous physical exercise. In addition, chest trauma or dry, hard food in the esophagus can cause bleeding.
avoid doing the Valsa maneuver
avoid lifting heavy weights
Avoid forceful coughing, sneezing, or blowing of the nose.
