In which situation should a phlebotomist apply pressure to the site after withdrawing the needle?

Applying pressure to the site after withdrawing the needle is essential in all cases as a standard practice in phlebotomy. This action helps to minimize the risk of hematoma formation, which can occur if blood leaks into the surrounding tissue. By applying adequate pressure, the phlebotomist promotes hemostasis, which aids in clot formation and helps to ensure that bleeding stops effectively.

Additionally, applying pressure can provide a sense of security for patients, as it reassures them that proper procedures are being followed, reducing anxiety about potential complications. In cases where a patient is on anticoagulant therapy or has clotting issues, applying pressure becomes even more crucial, underscoring the importance of this practice regardless of the specific situation or patient demographics.
