Answer to Question 1

ANS: D
For routine coagulation draws, a 20- or 21-gauge needle is used. The patient does not need to be fasting, the sodium citrate tube should be drawn first, and glass (syringe) should never be used for coagulation specimens because glass activates the contact phase.

Answer to Question 2

ANS: C
Clopidogrel is an antiplatelet function drug used for three reasons: (1) to treat patients with arterial occlusive disease; (2) for prevention of myocardial infarction; and (3) to decrease the risk of thrombotic stroke in patients with cerebrovascular disease and in patients who are intolerant of aspirin. It is increasingly being used in combination with aspirin to prevent arterial thrombosis.
