5 Liver Disorders and Nursing Care

Liver functions and care priorities

The liver processes nutrients and medications, produces bile and important blood proteins, stores energy, and helps regulate clotting. Liver disorders may cause inflammation or impaired bile flow; long-term injury can progress to fibrosis and cirrhosis. Early disease may have few symptoms.

Nursing care centers on recognizing deterioration, monitoring liver function and complications, supporting the treatment plan, and teaching patients how to reduce further injury.

Acute hepatitis and liver failure

Acute hepatitis is sudden liver inflammation. It may result from viral infections, medication or supplement toxicity, or other illnesses. Symptoms can include fatigue, nausea, right-upper-quadrant discomfort, dark urine, pale stools, itching, and jaundice, although some patients have few symptoms.

Acute liver failure is a medical emergency involving rapid liver injury, impaired clotting, and altered mental status in a person without pre-existing cirrhosis. Causes include acetaminophen toxicity, viral hepatitis, and other drugs or toxins. New confusion, unusual sleepiness, bleeding, or rapidly worsening jaundice requires urgent escalation. Management is hospital-based; suspected acetaminophen toxicity needs prompt evaluation for antidote treatment, and early specialist or transplant-center consultation may be needed.

Assess mental status, vital signs, bleeding, intake and output, and glucose as ordered. Review prescription medicines, over-the-counter products, alcohol, and supplements with the care team. Do not advise a patient to stop prescribed medicines without clinician guidance. Escalate suspected overdose or acute deterioration immediately.

Chronic viral hepatitis

Chronic hepatitis B or C can cause progressive liver injury, cirrhosis, and liver cancer. Treatment and follow-up depend on the virus and the patient’s condition. Nursing care includes supporting adherence to prescribed monitoring or antiviral therapy, reinforcing prevention and testing guidance, and helping patients keep recommended liver-cancer surveillance appointments.

Hepatitis B vaccination prevents hepatitis B; there is no hepatitis C vaccine.

Alcohol-associated liver disease

Alcohol-associated liver disease ranges from fatty liver and inflammation to cirrhosis. Care may include complete alcohol abstinence, treatment for alcohol use disorder, nutritional support, and management of complications. Use respectful, nonjudgmental language and offer appropriate support or referral. In advanced disease, assess for malnutrition and complications such as ascites, bleeding, infection, and encephalopathy.

Metabolic dysfunction and liver disease

Metabolic dysfunction-associated steatotic liver disease (MASLD) involves excess fat in the liver and is associated with metabolic risk factors such as obesity and type 2 diabetes. Some patients develop liver inflammation, fibrosis, and cirrhosis. Care generally addresses metabolic health and liver-disease risk with an individualized clinician-led plan.

Cirrhosis and other chronic disorders

Cirrhosis is advanced scarring that disrupts normal liver function. Causes include chronic viral hepatitis, alcohol-associated liver disease, MASLD, autoimmune or bile-duct disease, inherited conditions, and other causes. Cirrhosis may be compensated, with no major complications, or decompensated, when complications such as ascites, hepatic encephalopathy, or variceal bleeding develop.

Some less common chronic disorders include autoimmune hepatitis and cholestatic diseases such as primary biliary cholangitis and primary sclerosing cholangitis. These require disease-specific assessment and treatment by the clinical team.

Fluid buildup and infection

Bilirubin and bile-related substances can accumulate, causing jaundice and itching. Observe the skin and sclera, assess comfort and skin integrity, and report worsening jaundice.

Ascites and peripheral edema are associated with portal hypertension and altered fluid balance. Monitor abdominal girth as directed, daily weight, edema, breathing, intake and output, electrolytes, and renal function. New or worsening ascites needs clinical assessment. Hospitalized patients with cirrhosis and ascites may need diagnostic paracentesis to assess for infection.

Spontaneous bacterial peritonitis (SBP) is an ascitic-fluid infection. Possible signs include fever, abdominal pain or tenderness, confusion, low blood pressure, or worsening kidney function; symptoms can be subtle. Report suspected infection promptly.

Bleeding and clotting changes

Portal hypertension can cause enlarged veins, or varices, in the esophagus or stomach. These veins can rupture and cause life-threatening bleeding. Vomiting blood, coffee-ground emesis, or black, tarry stool requires an emergency response. If a patient with known varices vomits bright-red blood and feels faint, activate the emergency response and assess airway, breathing, circulation, and vital signs.

Cirrhosis can impair clotting through reduced clotting-factor production and other changes. Monitor for bruising and bleeding, review ordered coagulation tests, and use bleeding precautions appropriate to the patient.

Mental status changes and encephalopathy

Hepatic encephalopathy (HE) is brain dysfunction related to liver impairment or portosystemic shunting. It may cause sleep-pattern changes, inattention, personality changes, confusion, or reduced alertness. Infection, gastrointestinal bleeding, constipation, dehydration, electrolyte disturbance, and sedating medicines may contribute. Assess neurologic status and promptly report any change from baseline. HE is assessed clinically; do not rely on an ammonia result alone to determine severity.

For prescribed lactulose, monitor mental status, bowel pattern, hydration, and electrolyte status. Report excessive diarrhea or poor response. Frequent watery stools with dizziness or worsening weakness may indicate dehydration or electrolyte problems and need assessment and prompt clinician notification for clinician-directed adjustment. Rifaximin may be prescribed for some patients with recurrent HE. Assess for and help address precipitating causes such as infection, constipation, bleeding, or medication effects.

Nutrition and kidney complications

Reduced intake and altered metabolism may contribute to malnutrition and muscle loss. Assess weight trends, intake, and muscle strength; identify nutrition needs and coordinate with a dietitian and care team.

Advanced cirrhosis can also be complicated by hepatorenal syndrome, or kidney dysfunction. Monitor urine output, creatinine, blood pressure, and fluid status, and report deterioration promptly.

Assessment and interpretation of tests

Trend the whole clinical picture, including vital signs, mental status, jaundice, pain, bleeding, abdominal distension, edema, intake and output, weight, and laboratory results over time. Notify the clinician about meaningful changes rather than interpreting a single test in isolation.

Common tests provide different information:

• AST and ALT indicate hepatocellular injury.

• Alkaline phosphatase may rise with cholestasis or bile-duct disease.

• Bilirubin reflects processing and excretion.

• Albumin and PT/INR help assess synthetic function, though other influences can affect them.

• Platelets may fall with portal hypertension and splenic enlargement.

No single result alone establishes the cause or severity of liver disease. PT/INR, together with albumin, can help assess synthetic function, but should be interpreted alongside the clinical picture and other tests.

Medication and fluid management

Reconcile all prescribed and nonprescribed medicines, including acetaminophen-containing products, herbs, and supplements. Follow the prescriber’s plan and local protocols; do not independently withhold essential therapy. Suspected drug-induced liver injury requires prompt clinician review.

For ascites, reinforce the prescribed sodium plan, daily weights when ordered, and prescribed diuretics. Monitor blood pressure, renal function, and electrolytes. After paracentesis, follow local monitoring procedures and assess symptoms and vital signs. Do not impose fluid restriction unless it is prescribed.

Escalation and ongoing support

Emergency assessment is needed for vomiting blood, black or bloody stool, fainting or shock, rapidly worsening confusion, severe new abdominal pain with fever, or suspected overdose or acute liver failure. New confusion and fever in a patient with cirrhosis and ascites may indicate infection, including SBP, and may also reflect worsening HE; notify the clinician promptly and support urgent evaluation. Do not assume the change is expected or wait for an ammonia result before reporting it.

Support attendance at specialist appointments, recommended surveillance, and vaccination review. Reinforce alcohol abstinence when advised, medication safety, and timely reporting of confusion, fever, bleeding, increasing abdominal swelling, or reduced urine output. Decompensated cirrhosis warrants specialist assessment, including consideration of transplant evaluation when appropriate.
