Three Career Summaries

Three Career Summaries
1. Dental HygienistA degree from an accredited dental hygiene school and a state license are required for this
job. Dental hygienists remove soft and hard deposits from teeth, teach patients how to
practice good oral hygiene, and provide other preventive dental care. They examine
patients' teeth and gums, recording the presence of diseases or abnormalities. Dental
hygienists work in clean, well-lighted offices.
2. Registered NurseThe three typical educational paths to registered nursing are a bachelor's degree, an
associate degree, and a diploma from an approved nursing program. Registered nurses
treat patients, educate patients and the public about various medical conditions, and
provide advice and emotional support to patients' family members. RNs record patients'
medical histories and symptoms, help perform diagnostic tests and analyze results, operate
medical machinery, administer treatment and medications, and help with patient follow-up
and rehabilitation.
3. X-ray TechnicianFormal training programs in radiography are offered in hospitals or colleges and
universities and lead to a certificate, an associate degree, or a bachelor's degree. Most
States require licensure, and requirements vary. X-ray technicians produce x-ray films of
parts of the human body for use in diagnosing medical problems. They prepare patients for
radiologic examinations by explaining the procedure, removing jewelry and other articles
through which x rays cannot pass, and positioning patients so that the parts of the body can
be appropriately radiographed. To prevent unnecessary exposure to radiation, these
workers surround the exposed area with radiation protection devices, such as lead shields,
or limit the size of the x-ray beam. Radiographers position radiographic equipment at the
correct angle and height over the appropriate area of a patient's body.
