Answer to Question 1

ANS: D
Although the anticoagulant effects of warfarin begin in 8-12 hours, its peak effects do not occur for 48-72 hours. This is because the drug has no effect on existing clotting factors, which take from 6 to 60 hours to decay in the blood stream.

Answer to Question 2

ANS: C
Warfarin is contraindicated for use during pregnancy and lactation.
