Questions: Cirrhosis of the liver due to alcoholism is a common cause of: Hemostasis A deep vein thrombosis Myocardial infarctions Deficient coagulation

The answer is the fourth one: deficient coagulation.

Explanation for each option:

1. Hemostasis: Hemostasis is the process that stops bleeding at the site of an injury. While liver cirrhosis can affect hemostasis, it is not a direct cause of hemostasis itself. Instead, cirrhosis can lead to impaired hemostasis due to the liver's role in producing clotting factors.

2. A deep vein thrombosis: Deep vein thrombosis (DVT) is a condition where blood clots form in deep veins, usually in the legs. While liver cirrhosis can lead to changes in blood coagulation, it is not a common direct cause of DVT.

3. Myocardial infarctions: Myocardial infarctions, or heart attacks, occur when blood flow to a part of the heart is blocked. Cirrhosis of the liver is not a common direct cause of myocardial infarctions, although the overall health complications from cirrhosis can increase cardiovascular risks.

4. Deficient coagulation: The liver is responsible for producing many of the proteins necessary for blood clotting. Cirrhosis impairs the liver's ability to produce these proteins, leading to deficient coagulation. This means that individuals with cirrhosis are more prone to bleeding and bruising due to the lack of adequate clotting factors.

Summary: Cirrhosis of the liver due to alcoholism is a common cause of deficient coagulation. This is because the liver's ability to produce clotting factors is compromised, leading to an increased risk of bleeding.
