How many times can aspirin be administered?

• C. Three times
• D. Four times

Answer: (B)

For suspected acute coronary syndrome, aspirin is given as a single, chewable dose to rapidly inhibit platelet aggregation and help limit clot growth. This one-dose approach is recommended because an additional dose in the field doesn’t provide meaningful extra benefit and increases the risk of bleeding. The standard practice is to administer one dose (typically 162–325 mg) if there are no contraindications (such as allergy, active GI bleeding, or severe asthma with NSAID sensitivity) and the patient can chew and swallow. If symptoms persist or medical control directs otherwise, transportation and ongoing monitoring are the priorities, but the recommended action remains a single aspirin dose.
