A patient on aspirin can present with which of the following factors?

Aspirin ingestion irreversibly inhibits the synthesis of thromboxane A2 by platelets, which is necessary for platelet aggregation. Since platelet aggregation is impaired, bleeding time is increased. Bleeding time is indicative of function of platelets.
