Which route should aspirin be administered for chest pain in EMS?

• A. Swallowed whole
• B. Inhaled
• C. Chewed and swallowed
• D. Injected

Answer: (C)

Chewing aspirin and then swallowing it provides the fastest, most reliable antiplatelet effect in chest pain from suspected ACS. Crushing the tablet increases surface area and speeds dissolution and absorption, so the drug acts more quickly to inhibit platelet aggregation. That rapid onset is crucial when time matters for heart tissue. Swallowing a tablet whole slows absorption, and inhaled or injected routes aren’t appropriate ways to administer aspirin in this scenario. In EMS you’ll typically give a single chewable dose totaling about 162–325 mg.
