If a patient has already taken aspirin and a partial dose remains, what should EMS do?

• A. Do not administer any more
• B. Administer the remaining amount
• C. Double the total dose
• D. Withhold until next shift

Answer: (B)

When aspirin is part of the emergency treatment for suspected heart attack, the goal is to achieve a rapid antiplatelet effect by giving the full standard single-dose promptly. If the patient has already swallowed part of that dose, you should give the remaining portion to reach the full amount, as long as there are no contraindications (such as allergy, active internal bleeding, or other bleeding risk factors). This preserves the intended therapeutic effect without delaying care. Why this is the best approach: completing the dose maximizes the chance that platelet aggregation will be inhibited quickly, which can improve outcomes in acute coronary scenarios. Delaying or underdosing reduces potential benefit, while doubling the dose raises the risk of adverse effects, and withholding until a later time delays critical treatment.
