Topic 8: Hepatitis A, B, C Flashcards
Hepatitis
inflammation of the liver, most often caused by viruses, but other causes include substances (alcohol, medications) and autoimmune.
Hepatitis A transmission
fecal-oral route (contaminated food or drinking water, poor hygiene or proper handling of food)
Hepatitis B transmission
blood borne pathogen, blood and body fluid (IV drug use, tattoos body piercings- contaminated needles, unprotected sex- semen and vaginal secretions, mothers to their infants)
Hepatitis C transmission
blood borne primarily transmitted percutaneously (sharing contaminated needles, high risk sexual activities among MSM with HIV infection)
Clinical Manifestations for Acute Hepatitis
· Flu-like symptoms (HA)
· Jaundice
· Clay-colored stools
· Dark urine (due to excess bilirubin excreted by kidneys)
· Fatigue, lethargy, malaise
· Low grade fever
· Pruritus
· RUQ tenderness
· Splenomegaly, hepatomegaly
· N/V, diarrhea or constipation
· Decreased sense of taste and smell
· Anorexia and weight loss
what is the urine and stool appearance in a patient with acute hepatitis
· Clay-colored stools
· Dark urine (due to excess bilirubin excreted by kidneys)
why is pruritus a clinical manifestation of acute hepatitis
due to accumulation of bile salts beneath the skin
what location is tenderness felt in a patient with acute hepatitis
RUQ
Clinical Manifestations for Chronic Hepatitis
· AST, ALT elevations
· Ascites and lower extremity edema
· Asterixis (“liver flap”)
· Bleeding abnormalities (thrombocytopenia, easy bruising, prolonged clotting time)
· Fatigue, malaise
· Hepatic encephalopathy: confusion, difficulty concentrating, easy agitation
· Increased bilirubin
· Jaundice
· Palmar erythema
· Spider angioma
· Myalgias/arthralgia
· Hepatomegaly
diagnostic studies for hepatitis
· To distinguish among the types of viral hepatitis, testing of patients’ blood for specific antigen or antibody
Liver biopsy
lab results for hepatitis
increase AST and ALT
increased bilirubin
management for acute VIRAL hepatitis
most managed at home
· Adequate nutrition
· Rest the body to help liver regenerate and repair
· Avoid alcohol
Health Promotion Hepatitis A
· Hand washing, proper personal hygiene
· Environmental sanitation
· Control and screening of food handlers
· Serologic screening for those carrying the virus
· Active immunization: HAV Vaccine
Health Promotion Hepatitis B and C
· Hand washing
· Avoid sharing tooth-brush and razors
· HBIG administration for one-time exposure (needle stick, contact of mucous membranes with infections material
· Active immunization: HBV vaccine
· Condoms for sexual intercourse
comfort measures for pruritis
hydration, mosturizer, avoid irritants
