Final answer:
Ischemic hepatic injury should be suspected in the presence of low oxygen levels, which can lead to impaired blood flow and oxygen deprivation to liver cells. Conditions like low blood pressure and heart failure are typical examples leading to hepatic ischemia.
Step-by-step explanation:
You should suspect ischemic hepatic injury in the presence of low oxygen levels (option c). Ischemic liver injury, or hepatic ischemia, occurs when the liver cells are deprived of oxygen and nutrients. This can happen in a variety of conditions, such as low blood pressure, heart failure, or anything that impairs blood flow to the liver.
Acute liver failure can be indicated by the development of hepatic encephalopathy and decreased production of proteins within a short period after the first symptoms of a liver issue. This may be seen following severe injury or acute viral infection. In contrast, cirrhosis is a form of chronic liver failure caused by fibrous tissue replacing dead liver cells, which may be due to factors including viral hepatitis, alcoholism, or exposure to other liver-toxic substances.
