the nurse is reviewing laboratory results of a client who has liver failure. which finding would place the client at increased risk for bleeding? increased levels of vitamin k increased prothrombin time increased platelet count decreased number of red blood cells

Respuesta :

Increased prothrombin time.

Patients with liver failure have decreased vitamin K absorption, which affects the body's ability to synthesize clotting components. The client is more likely to bleed if their prothrombin time, a coagulation factor, is elevated. The liver produces prothrombin, fibrinogen, and factors V, VII, IX, and X; as their production decreases with liver illness, bleeding disorders result. Increased bleeding won't result from a drop in RBC. The blood will clot as a result of an elevated platelet count.

What is prothrombin?

The liver produces the protein called thrombin. Blood clotting is aided by prothrombin. The "prothrombin time" (PT), which is measured in seconds, is one approach to determine how long it takes blood to clot (such as 13.2 seconds). The availability of blood-clotting protein is indicated by a normal PT.
