Answer to Question 1

D
Feedback:
Injectable vitamin K is used to reverse the effects of warfarin. Vitamin K is responsible for promoting the liver synthesis of several clotting factors. When these pathways have been inhibited by warfarin, clotting time is increased. If an increased level of vitamin K is provided, more of these factors are produced, and the clotting time can be brought back within a normal range. Green leafy vegetables are high in vitamin K and should be avoided or minimized in the diet to prevent reversal of warfarin effects. The other food options are not high in vitamin K.

Answer to Question 2

D
Feedback:
The patient should use an electric razor to shave rather than a disposable razor that could nick his skin and increase risk of bleeding. Carrying a MedicAlert card, getting regular follow-up lab work, and use of acetaminophen would all be appropriate actions that would not indicate the need for further teaching.
