Which of the following are common signs of liver failure?

The presence of jaundice, ascites, confusion, and easy bruising as common signs of liver failure is well-established in medical literature.

Jaundice occurs when there is an accumulation of bilirubin in the blood due to the liver's inability to process it effectively. This leads to a yellowing of the skin and eyes, which is a hallmark sign of liver dysfunction. Ascites, the accumulation of fluid in the abdominal cavity, can occur due to increased pressure in the portal vein and decreased protein production by the liver, leading to a variety of complications. Confusion, or hepatic encephalopathy, is a result of the liver's reduced ability to filter toxins from the blood, which can affect brain function. Easy bruising is associated with liver failure because the liver produces many of the proteins necessary for blood clotting, and a deficiency in these proteins can lead to an increased tendency to bruise.

In contrast, the other options provided do not directly correlate with liver failure. Fever and abdominal pain can indicate infections or inflammation but are not specific signs of liver failure. Chest pain, dyspnea, and tachycardia are often indicative of cardiovascular problems rather than hepatic issues. Lastly, dry skin, excessive thirst, and hair loss can
