A patient presents with non-traumatic chest pain. Which action is most appropriate?

• A. Chew 160-325 mg aspirin unless contraindicated
• B. Lie down and rest
• C. Give water and oxygen
• D. Wait for EMS

Answer: (A)

When chest pain suggests possible acute coronary syndrome, the priority is to interfere with the clotting process to reduce heart muscle damage. Chewing aspirin and taking a total of 160-325 mg rapidly inhibits platelets, helping prevent further clot growth in the coronary artery and lowering early mortality. Chewing speeds absorption, giving a faster effect than swallowing whole tablets. Only give aspirin if there are no contraindications such as allergy, active bleeding, or a history that makes NSAIDs unsafe. Rest or waiting doesn’t address the underlying issue quickly enough, and water or unnecessary oxygen without indications won’t improve the outcome. Administer chewable aspirin now, then activate EMS and monitor the patient.
