Which of the following conditions is a contraindication to aspirin use?

• A. Pregnancy
• B. All of the above
• C. Intestinal bleeding
• D. Taking a medication to prevent clotting

Answer: (B)

Aspirin is an antiplatelet medication used to help in suspected heart attack, but it isn’t safe in certain situations where bleeding or harm could occur. Pregnancy is a contraindication because aspirin can affect the fetus and increase bleeding risk during pregnancy. Intestinal bleeding is a clear red flag—aspirin can worsen bleeding in the GI tract. If a patient is taking a medication to prevent clotting, adding aspirin raises the risk of excessive bleeding due to additive antiplatelet effects. Because each of these scenarios makes aspirin dangerous, the correct choice is that all of these apply. In practice, you would withhold aspirin if any of these contraindications are present and proceed with other EMS treatments as indicated.
