Emergency medicine is a subspecialty that focuses on patients who need immediate and often intensive care. These physicians must be able to handle medical problems quickly to avoid potential complications with their patients. With their knowledge of emergency medicine comes knowledge about many other types of medicine, as they must be able to respond to patients who present a variety of symptoms and problems. They will also have a thorough understanding of emergency medical devices.

A nurse practitioner is a registered nurse who has gone through additional training to provide more advanced medical and diagnostic care to patients with all different kinds of illnesses. These medical professionals generally hold at least a master’s degree, so they have a comprehensive basis of medical knowledge to help patients suffering from chronic and acute conditions. They may work in hospitals, intensive care units, hospice centers, and even doctor’s offices, depending on their specialty.
