A

2 weeks up to 1-4 months post transmission
Flu-Like sx
N/V, Anorexia

Joint pain

25
what are some labs/diagnostics for hep B
LFTs (AST / ALT) CT / Ultrasound HBV antibodies Liver Biopsy
26
what are some acute interventions for hep B
Rest Nutrition / Fluids Antivirals (chronic flare-up)
27
what are some complications of hep B
Cirrhosis Liver Failure / Liver CA Kidney / Vascular issues Portal HTN -> esophageal varices
28
describe nursing focus and education for hep B
Vaccinate! Can fully recover (>90%) Discuss liver transplant options (chronic) Keep liver happy = avoid alcohol and certain meds during flare-ups Nurse = Wear gloves = ALWAYS Discuss how to prevent transmission Nurse safety
29
what are some causes of cirrhosis
- liver diseases (hep and alcoholism) - chronic obesity - certain meds (methotrexate and isoniazid)
30
whats happening with cirrhosis
Later stage of scarring of liver Liver can only regenerate for so long Scar tissues to portal areas Biliary duct obstruction Hepatocytes to fat to scarred
31
how will the client with cirrhosis present
Fatigue Easily bleeding / ecchymosis Nausea and anorexia Edema to legs, feet, ankles, and abdomen (ascites) Weight loss Jaundice Confusion, drowsiness, slurred speech Late finding = GI varices and Caput Medusa
32
how can nurses help with cirrhosis
- Vitamin replacement (banana bags) - Assess for esophageal varices - Pain control - Monitor for mental deterioration - Educate on drinking cessation - Complications of immobility - Falls risk! - Bleeding risk! - Discuss how to protect against Hepatitis - Liver transplant
33
what are some labs and diagnostics for cirrhosis
- LFT - INR, BMP - MRI, CT, US - biopsy
34
what are some acute interventions for cirrhosis
- pain control - nutrition replacement - complication control (varices)
35
what are some complications of cirrhosis
- portal HTN - bleeding - splenomegaly - edema - malnutrition - hepatic enchalopathy
36
what are some meds that can help with cirrhosis
- meds for hep B and C - antibiotics for infection - BP medication to control portal (really needs to be controlled) - K sparing diuretics - lactulose: binds to ammonia so you shit it out, can lead to falls, dehydration, and fatigue - antifibrotic meds (colchicine, ACEs, statins, immunosuppressants): prevent scarring
