Cirrhosis nursing care: what to assess and what to do first
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
Cirrhosis nursing care focuses on managing the complications of a scarred, failing liver: ascites, bleeding risk, and hepatic encephalopathy. As the liver fails, ammonia builds up because it can no longer be converted to urea, which is why confusion is treated with lactulose to clear ammonia rather than with sedatives that would worsen it.
The pathophysiology in one pass
Cirrhosis is irreversible scarring of the liver, usually the end result of years of chronic injury from alcohol use, viral hepatitis, or non-alcoholic fatty liver disease. Healthy hepatocytes are replaced by fibrotic tissue, and that scarring distorts the liver's architecture, raising resistance to blood flow through the portal system.
That rising resistance is portal hypertension, and it drives most of what nurses manage clinically: fluid backs up and leaks into the peritoneal cavity as ascites, pressure diverts blood into fragile collateral vessels like oesophageal varices, and the spleen enlarges as it congests. At the same time, the failing liver loses its synthetic functions — it can no longer make clotting factors reliably, clear bilirubin efficiently, or convert ammonia to urea for excretion. That last failure is what drives hepatic encephalopathy.
Assessment findings that matter
Look for jaundice, spider angiomata, and palmar erythema as visible signs of impaired liver metabolism, alongside a distended, fluid-filled abdomen from ascites. Measure abdominal girth daily at a marked, consistent point and weigh the patient daily — both are more sensitive to fluid shifts than a visual estimate.
Assess mental status at every shift using a structured scale, watching for the shift from subtle personality change through drowsiness to frank confusion that marks progressing hepatic encephalopathy. Asterixis, the flapping tremor elicited by asking the patient to extend their arms and dorsiflex the wrists, is a hallmark finding worth checking specifically rather than waiting to notice incidentally. Also track for bruising or oozing from IV sites, since a failing liver cannot produce adequate clotting factors, and monitor skin and sclera colour trends over the admission, not just at a single point in time.
What the exam asks about this
Expect questions that pair a rising ammonia level with new confusion and ask you to identify the correct intervention — the answer is almost always lactulose, not a benzodiazepine or other sedative. Sedatives are metabolised by the liver, accumulate in liver failure, and worsen encephalopathy, which is exactly the trap these questions are testing for.
You will also see questions on prioritising airway and bleeding risk in a patient with suspected variceal haemorrhage, on correctly interpreting ascites and low albumin together, and on recognising spontaneous bacterial peritonitis from fever and abdominal pain in a patient with known ascites. Knowing why lactulose works — trapping ammonia in the gut as ammonium and promoting its excretion in stool — helps you reason through variations on the question rather than just recalling the drug name.
Nursing interventions in priority order
Airway and bleeding come first if variceal haemorrhage is suspected: large-bore IV access, type and crossmatch, and close monitoring for haematemesis or melena, since a bleeding varix can exsanguinate quickly. Outside of an acute bleed, ascites management and encephalopathy prevention take priority.
Sodium restriction and diuretics — typically spironolactone paired with furosemide — reduce ascites, and paracentesis may be needed for tense or symptomatic accumulation, with post-procedure monitoring for hypotension as fluid shifts. Elevate the head of the bed to ease respiratory effort against a distended abdomen. Reorient a confused patient gently and frequently, remove fall hazards, and avoid any medication that requires hepatic clearance unless it has been specifically reviewed for this patient.
Medications and monitoring
Lactulose is titrated to produce two to three soft stools daily, which is the clinical target that confirms ammonia is being cleared rather than a fixed dose given regardless of effect. Rifaximin is often added for encephalopathy that does not respond to lactulose alone, working by reducing ammonia-producing gut bacteria.
Monitor ammonia levels alongside mental status, though the two do not always track perfectly, so clinical assessment remains the more reliable day-to-day measure. Track INR, platelets, and albumin as markers of synthetic liver function, and monitor potassium and renal function closely in anyone on diuretics for ascites, since electrolyte disturbance itself can precipitate encephalopathy.
When to escalate
Escalate immediately for haematemesis, melena, or a sudden drop in blood pressure, all of which suggest variceal bleeding and warrant urgent intervention. Escalate for a rising grade of encephalopathy, particularly any move toward lethargy or unresponsiveness, since airway protection becomes a concern once a patient can no longer protect it reliably.
Fever with abdominal pain in a patient with ascites should raise suspicion for spontaneous bacterial peritonitis and needs prompt reporting for paracentesis and culture. Sudden weight gain, worsening shortness of breath, or decreasing urine output alongside ascites can indicate rapidly accumulating fluid or evolving hepatorenal syndrome, both of which need timely escalation rather than routine documentation.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our gastrointestinal practice questions are the closest set to what this page covers.
Common questions
Why is lactulose used for confusion in cirrhosis instead of a sedative?
Confusion in cirrhosis is caused by rising ammonia that the failing liver can no longer convert to urea, and lactulose treats that directly by trapping ammonia in the gut and promoting its excretion. Sedatives would worsen the confusion because they are metabolised by the liver and accumulate in liver failure.
How is lactulose dosed for hepatic encephalopathy?
Lactulose is titrated to achieve two to three soft bowel movements per day, not given at a fixed dose regardless of response. The stool output is the clinical marker that ammonia is being effectively cleared.
What is asterixis and why does it matter in cirrhosis?
Asterixis is a flapping tremor of the hands, elicited by asking the patient to extend their arms with wrists dorsiflexed, and it is a hallmark sign of hepatic encephalopathy. Checking for it specifically, rather than waiting to notice it incidentally, helps catch worsening encephalopathy earlier.
Why do cirrhosis patients bruise or bleed easily?
The liver produces most clotting factors, and cirrhosis impairs that synthetic function, leaving patients with prolonged clotting times and a higher bleeding risk. This is why INR is monitored routinely and why any bruising, oozing, or overt bleeding needs prompt attention.
What signs suggest spontaneous bacterial peritonitis in a cirrhosis patient?
Fever and abdominal pain in a patient with known ascites should raise suspicion for spontaneous bacterial peritonitis, sometimes with subtler signs like worsening confusion or general decline. It requires prompt reporting for diagnostic paracentesis and fluid culture rather than being assumed to be routine ascites discomfort.
