American Medical Technologist (AMT) Practice Exam

When a phlebotomist encounters a hematoma during venipuncture, the appropriate action is to apply pressure and withdraw the needle. A hematoma occurs when blood leaks from the vein into the surrounding tissue, often caused by the needle puncturing through the vein or improper technique.

Applying pressure helps to minimize further bleeding by constricting the blood vessels and aids in the absorption of the leaked blood. Withdrawing the needle immediately prevents additional injury to the tissue and stops the bleeding. It is important to ensure that the site is adequately managed, which often includes applying pressure for a sufficient duration to prevent rebleeding.

Continuing the procedure or switching to a larger needle is not advisable, as these actions could exacerbate the situation and increase the risk of complications. Waiting for the patient to relax is unnecessary and may lead to further discomfort or anxiety for the patient. Prompt and proper action is essential in managing any complications that arise during blood collection to ensure the safety and well-being of the patient.
