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. A Registered Nurse (RN) is a nurse who has graduated from a nursing program and met the requirements outlined by a country, state, province or similar licensing body in order to obtain a nursing license. An RN's scope of practice is determined by legislation, and is regulated by a professional body or council.
Nursing Role The Registered Nurseâs (RN) unique role on the health care team is the ongoing assessment of the patient's health status and the patientâs response to their plan of care. For example, in the hospital setting the registered nurse is often the health care professional who spends the most time directly with the patient, providing around the clock observations and care.
