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.
Registered Nurses, or RN's. Registered nurses hold the highest nursing position in nursing homes, as they oversee the activities of the rest of the nursing staff. Instead of just focusing on the immediate needs of patients, RNs are responsible for overseeing each patient's overall health and medical histories.
