Correct Answer : A,B,E

C. Reduced appetite is incorrect; while some individuals may experience appetite changes, a reduced appetite is not an indicator of effectiveness and could indicate a side effect.

Correct Answer is C
Explanation
A. Short-acting insulin does not cover basal needs; that is the role of long-acting insulin.
B. Intermediate-acting insulin does not primarily cover mealtime glucose spikes; it provides a more prolonged effect.
C. Short-acting insulin is used to manage blood glucose during meals, while intermediate-acting insulin helps maintain glucose control between meals and overnight, making this the correct choice.
D. Short-acting and intermediate-acting insulins have different onset and peak times; they do not share the same pharmacokinetic properties.
Correct Answer is A
Explanation
A. An INR of 5.0 indicates a significantly increased risk of bleeding, and administering vitamin K is the appropriate antidote for reversing the effects of warfarin. This is a critical intervention to restore coagulation.
B. Increasing the dose of warfarin is inappropriate in this scenario because the INR is already elevated; it would further increase bleeding risk.
C. While heparin can be used for anticoagulation, it is not appropriate to administer it while the INR is dangerously high without reversing the warfarin first.
D. Continuing warfarin is unsafe at this INR level due to the high risk of bleeding; monitoring for symptoms without intervention is not adequate care.
