Correct answer: C — 325 mg chewed
During a suspected acute MI in the dental office, aspirin 325 mg should be administered immediately (chewed for rapid absorption through the buccal mucosa rather than swallowed, reducing time to peak plasma levels from 60 minutes to approximately 15 minutes). Aspirin inhibits further platelet aggregation at the site of coronary thrombosis. Contraindication: true aspirin allergy. This should be given while awaiting EMS arrival.
