Answer to Question 1

ANS: A
This patient has an INR in the appropriate range, so no change in warfarin dosing is necessary. It is not correct to request an order to either decrease or increase the dose of warfarin. It is not necessary to give vitamin K, which is an antidote for warfarin toxicity.

Answer to Question 2

ANS: D
This patient is exhibiting signs of pulmonary embolism. Heparin is used when rapid onset of anticoagulants is needed, as with pulmonary embolism. The patient would have respiratory cracks and a cough with congestive heart failure. Hemorrhage involves a decrease in blood pressure, bruising, and lumbar pain. The patient has pleuritic pain, which is not consistent with the chest pain of an MI.
