A patient with an ST-segment elevation MI has ongoing chest discomfort. Fibrinolytic therapy has been ordered. Heparin 4000 U IV bolus was administered and a heparin infusion 100 U per hour is being administered, and Aspirin was not taken by the patient because he had a history of gastritis treated 5 years ago. Your next action is to:
|
|
Give 325 mg enteric-coated aspiring rectally
|
|
|
Substitute clopidogrel 300 mg loading dose
|
|
|
Give 75 mg enteric-coated aspirin only
|
