A client who is taking clopidogrel (Plavix) to prevent another stroke asks a nurse how the medication works. The nurse s response should be based upon an understanding that Plavix:

1. Prolongs the bleeding time by inhibiting platelet aggregation.

2. Activates antithrombin III and subsequently inhibits thrombin.

3. Inhibits enzymes involved in the formation of vitamin K.

4. Converts plasminogen to plasmin to dissolve fibrin clots.
