A nurse is caring for a patient with liver failure and is performing an assessment in the knowledge of the patient's increased risk of bleeding
The nurse recognizes that this risk is related to the patient's inability to synthesize prothrombin in the liver. What factor most likely contributes to this loss of function?
A) Alterations in glucose metabolism
B) Retention of bile salts
C) Inadequate production of albumin by hepatocytes
D) Inability of the liver to use vitamin K
Ans: D
Feedback:
Decreased production of several clotting factors may be partially due to deficient absorption of vitamin K from the GI tract. This probably is caused by the inability of liver cells to use vitamin K to make prothrombin. This bleeding risk is unrelated to the roles of glucose, bile salts, or albumin.
