Which of the following is an example of exclusion criteria for tPA administration?

• A. Obesity
• B. Bleeding diathesis
• C. Hypertension
• D. Diabetes Mellitus

Answer: (B)

In the context of tPA (tissue plasminogen activator) administration, exclusion criteria are conditions that would prevent the use of this medication due to an increased risk of adverse effects, primarily bleeding complications. Bleeding diathesis refers to a tendency to bleed easily and can result from various factors, including clotting disorders or the use of anticoagulant medications. Since tPA works by dissolving clots, administering it to a patient with bleeding diathesis significantly raises the risk of serious hemorrhagic events. Therefore, this condition is a critical exclusion criterion for tPA use. In contrast, while obesity, hypertension, and diabetes mellitus may be associated with other risks and complications in stroke management, they do not inherently contraindicate the use of tPA like bleeding diathesis does. Hypertension, for instance, can be managed and may be addressed prior to tPA administration, but it doesn't automatically exclude a patient from receiving the treatment unless it is excessively elevated. Similarly, obesity, while potentially complicating treatment outcomes, does not directly impact the safety of tPA administration itself.
