A hematoma is a larger collection of blood, usually caused by surgery, injury, or a greater trauma. Hematomas will usually reabsorb into the body, like a bruise. However, depending on the size, location and cause of the hematoma, the area may need to be drained surgically, or take a longer period of time to resolve.
Registered nurse.

What Is the Difference Between RN and BSN Degrees? A registered nurse (RN) is a nurse who has passed the National Council Licensure Examination for Registered Nurses (NCLEX-RN) after completing an accredited training program.
