Answer to Question 1

C
Feedback:
PT and INR are ordered to evaluate for therapeutic effects of warfarin. Normal values of PT is 1.3 to 1.5 times the control value and the ratio of PT to INR is 2 to 3.5.

Answer to Question 2

D
Feedback:
Regular insulin is a short-acting insulin that manages the hyperglycemia and hyperkalemia resulting from DKA, which is a life-threatening complication that occurs with severe insulin deficiency. Furthermore, only regular insulin can be given IV and is the drug of choice in emergency situations. Humulin N, Humulin L, and NPH are intermediate-acting forms.
