Answer to Question 1

A
Feedback:
Vitamin K is used to reverse the effects of warfarin (Coumadin).

Answer to Question 2

D
Feedback:
For acute asthma attacks, subcutaneous (Sub-Q) administration of epinephrine usually produces bronchodilation within 5 to 10 minutes; maximal effects may occur within 20 minutes. An increase in LOC is not a priority, and respiratory rate would not likely decrease.
