Which of the following is a common complication that may arise during phlebotomy?

Hematoma formation is a common complication that may arise during phlebotomy due to the nature of the procedure, which involves puncturing a vein. When a needle is inserted into a vein for blood collection, there is a potential for blood to leak out of the vessel into the surrounding tissue. This leakage can occur if the needle punctures through the vein, or if the vein is breached, leading to an accumulation of blood and resulting in a localized swelling known as a hematoma.

Patients may notice a bruise or swelling at the puncture site after the procedure, which is typically benign but can cause discomfort or concern. Hematomas can be minimized by using proper techniques, such as not applying excessive pressure on the site post-venipuncture and ensuring that the needle is correctly placed within the lumen of the vein. Understanding this complication is crucial for phlebotomists to manage patient care effectively and to reassure patients regarding any post-procedure effects.
