Social workers conduct psychotherapy and assist individuals with problems such as poverty, illness, substance abuse, lack of financial management skills, or inadequate housing. They help people find the resources to solve financial, health care, family and other problems. Becoming licensed requires obtaining a bachelor's degree in social work and passing an examination. They select and set up appropriate equipment for the test, explain the procedure to patients, help patient to assume the correct physical position, and put patients at ease. Sonographers observe the sound-wave display screen, adjust equipment to ensure a clear image, and maintain a log of ultrasonic tests.
Training is one, two or four years in length.
The one-year program is for those who have met qualification requirements in health care. They use medical instruments, radiographic images and other recordings of internal organs to examine and treat patients. Surgeons also prescribe medications and dietary and activity programs. New technology allows doctors to perform more tests and procedures, and in some cases, surgeons can now treat conditions that were previously seen as untreatable. The education is typically a four-year bachelor's degree, four years of medical school, three years of residency, and a subspecialty fellowship of two or more years.
