A patient with ST-segment elevation MI has ongoing chest discomfort. Fibrinolytic
therapy has been ordered. Heparin 4000 units IV bolus was administered, and a
heparin infusion of 1000 units per hour is being administered. Aspirin was not taken by
the patient because he had a history of gastritis treated 5 years ago. Your next action is
to:
1. Give aspirin 160 to 325 mg chewed immediately.
2. Give 75 mg enteric-coated aspirin orally.
3.Give 325 mg enteric-coated aspirin rectally.
4. Substitute clopidogrel 300 mg loading dose. - ANSWER_ 1. Give aspirin 160 to 325
mg chewed immediately.
