Dieticians plan nutritional programs and supervise the planning and serving of meals. The basic educational requirement is a bachelor's degree with a major in dietetics, food and nutrition, food systems management or a related area. Most states require additional certification. Good Emergency medical technicians are first responders who give immediate care to those needing urgent medical attention following automobile accidents, gunshot wounds, near drownings, heart attacks and other emergencies. EMT basic training is 100-120 hours of classroom work plus 10 hours of internship in a hospital emergency room.
Training is through police, fire and health departments, and at community colleges.
