Hepatitis Flashcards
PATHOPHYSIOLOGY
- inflammation of the liver
- impedes processes and function of the liver
- prevalent throughout the world
- generally results from underlying infectious agent or virus
- may be acute or chronic
- mild or life threatening
ETIOLOGY AND PATHO
- INFLAMMATORY PROCESS
- damages hepatic cells
- disrupts liver function
2.DEGREE OF IMPAIRMENT DEPENDS ON CAUSE, SPEED OF DEVELOPEMENT
- CAUSES
- virus, toxins, other pathogen
- alcohol or drug abuse
ETIOLOGY
- cell mediated immune response ( damage hepatocytes, kupffer cells leads to hyperplasia and necrosis)
- locally in liver or as systemic disease
- non-viral hepatitis
- viral hepatitis
(HAV,HBV,HCV,HDV,HEV)
(chronic hepatitis caused by B,C,E)
(fulminant hepatits)
RISK FACTORS AND PREVENTION
-risk factors, preventive actions vary according to cause of hepatitis
MOST COMMON: autoimmune disorders alcoholism contaminated food, water infected blood sexual contact with contaminated blood , body fluids
CLINICAL MANIFESTATIONS
- similar for acute and chronic
- can manifest with no or nospecific symptoms or debilitating symptoms
INCUBATION PHASE
- usually asymptomatic for acute hepatitis
- HBeAg in blood indicates high degree of HBV infection
- as incubation progresses, HBsAg appears
PRODROMAL PHASE
- occurs between exposure to virus and appearance of clinical manifestations
- jaundice, nausea, vomiting, malaise, fatigue
- mild RUQ pain, fever
ICETERIC PHASE
-begins 5-10 days after initial symptoms manifest
CONVALESCENT PHASE
- follows 2-3 weeks of acute illness
COLLABORATION
-treatment primarily supportive
(rest, proper nutrition, may need to increase protein, avoid alcohol)
- client education
(prevention, long term management , address risky behaviors)
DIAGNOSTIC TESTS
- show extent of liver impairment
-ALT
ALP
LDH
AST
GGT
serum bilirubin
liver biopsy
PHARMOCOLOGIC THERAPY
-most clients with acute hepatitis recover without pharmacologic treatment
- medications available : vaccines immune globulin interferon alpha (chemo type drug) antiretroviral drugs
NURSING PROCESS
- alleviate symptoms
- provide client education regarding nutrition , lifestyle management
ASSESSMENT
- health history
- physical assessment
abdominal, epigastric pain
nausea,vomiting,anorexia
fever, joint pain, malaise, jaundice
assess for infection transmission, nutritional status
DIAGNOSES
- imbalanced nutrition
- risk for impaired skin integrity
- infection
- fatigue
- deficient knowledge
- nausea
