Which condition would typically contraindicate the use of chewable aspirin in suspected ACS?

• A. Active GI bleeding
• B. History of allergies to aspirin
• C. Asthma
• D. Recent vaccination

Answer: (A)

In suspected ACS, chewable aspirin is given to inhibit platelet aggregation and help prevent further clotting, reducing heart muscle damage. The condition that would typically contraindicate its use is active GI bleeding because aspirin can further impair clotting and worsen bleeding in the gastrointestinal tract, potentially leading to serious hemorrhage. Allergies to aspirin are also a contraindication, but the most immediate and clear contraindication in this context is active GI bleeding. Asthma can complicate aspirin use in some individuals, but it is not an automatic contraindication for all patients, and recent vaccination has no bearing on this decision.
