Professions frequently pursued by Hofstra students after graduation

PHYSICIAN
Physicians serve a fundamental role in our society and have an effect upon all our lives. They diagnose illnesses and prescribe and administer treatment from people suffering from injury or disease. They examine patients, obtain medical histories, and order, perform, and interpret diagnostic tests. They counsel patients on diet, hygiene, and preventative health care. There are two types of physicians: The M.D.-Doctor of Medicine-and the D.O.-Doctor of Osteopathic Medicine. About one-third of M.D.'s are primary care physicians. They practice general and family medicine, general internal medicine, or general pediatrics and are usually the first health professionals patients consult. D.O.'s place special emphasis on the body's musculoskeletal system, preventative medicine, and holistic patient health care.

PHYSICIAN ASSISTANT
The physician assistant is academically and clinically prepared to practice medicine with the direction and responsible supervision of a doctor of medicine or osteopathy.

Cardiovascular and electroneurodiagnostic technicians and technologists monitor the functioning of the heart and brain, respectively. Perfusionists monitor the heart, lungs and circulation during surgery and can provide long-term care. Radiation therapists administer radiation to patients with cancer. Radiographers process and produce high-quality x-ray photographs or medical images of internal body structures. Surgical technologists maintain the sterility of all surgical equipment and assist physicians during procedures. Dosimetrists determine and monitor the dosage amounts of radiation. Ultrasound technologists use complex ultrasound equipment to produce two-dimensional ultrasonic recordings that show the shape, position, and movement of internal organs; the accumulation of fluid in the body; of the presence of various masses, such as a tumor or fetus. Biomedical engineers and biomedical equipment technicians must produce and maintain intricate equipment and machinery, which are used to cure illnesses and save lives. The health care professionals responsible for using this equipment properly are highly trained in both the technical and medical aspects of their respective fields.
