The rationale for identifying allergies to aspirin or a history of gastrointestinal bleeding as contraindications is grounded in patient safety and the mechanism of action of the drug. Aspirin is an anticoagulant that can increase the risk of bleeding; therefore, in patients who have experienced gastrointestinal bleeding previously, the administration of aspirin could exacerbate their condition and lead to serious complications.

Additionally, individuals with an allergy to aspirin could suffer from potentially severe allergic reactions, such as anaphylaxis, which can be life-threatening. Thus, confirming the patient's medical history regarding allergies and previous bleed events is a critical step before administering aspirin.

The other options do not align with the medical guidelines regarding aspirin's uses and contraindications. For example, the age of the patient or the presence of high blood pressure do not inherently preclude the use of aspirin in a cardiac context unless accompanied by other relevant factors. Similarly, the alertness of a patient generally does not serve as a contraindication to aspirin administration.
