NHA Phlebotomy Certification Practice Exam

Why should phlebotomists avoid drawing blood from a diabetic patient's leg or foot?

1. These areas are more prone to hematomas

2. These areas have better blood flow

3. These areas are more susceptible to infection

4. These areas are difficult to access

The correct answer is: These areas are more susceptible to infection

In the context of drawing blood from diabetic patients, avoiding the leg or foot is primarily due to the increased susceptibility to infection in these areas. Diabetic patients often experience reduced circulation and nerve function, which can lead to slower healing and a higher risk of complications following procedures such as venipuncture. The skin integrity in diabetic patients may also be compromised, making it more vulnerable to infection. Furthermore, if blood is drawn from these lower extremities, any resulting infection can spread more easily, complicating the patient's overall health management. Hence, phlebotomists are trained to prioritize safer sites for venipuncture that pose less risk for such complications.
