Clinical nurse specialists (CNSs) plan, direct and coordinate the daily patient care activities in a clinical practice. CNSs ensure adherence to clinical policies, protocols, regulations and standards.

Anesthesiologists are physicians who deliver pain-relieving medications during surgical procedures and monitor patients’ vital signs. In addition to working with patients in the operating room, anesthesiologists also provide pain relief services to people who suffer from chronic pain, during labor and delivery, and to patients in the intensive care unit. They work closely with surgeons and other physicians to formulate a treatment plan before, during and after a surgical procedure.

Internists are physicians who diagnose and provide non-surgical treatment of disease and injuries of internal organ systems. They provide care mainly for adults who have a wide range of problems associated with the internal organs.
