Answer to Question 1
ANS: C
Liver disease particularly affects production of the vitamin Kdependent proteins. Because the PT is sensitive to factor VII activity and it (factor VII) has a short half-life of 3 to 5 hours, the PT is the most sensitive for detecting mild liver disease.
Answer to Question 2
ANS: A
Factor V is not vitamin K dependent, but it is produced in the liver so it is decreased in moderate to severe liver disease. Factors VII and IX are both vitamin K dependent, so they are decreased in both liver disease and vitamin K deficiency. Factor VIII is not decreased in either liver disease or vitamin K deficiency; in fact, because it is an acute phase reactant, it may actually be elevated in mild to moderate liver disease.
