The length of programs for nursing assistant certification varies widely between states and educational centers. Federal law indicates that each certification program contain a minimum of 75 combined instructional and clinical hours, approved by each state's board of nursing.
Certified nursing assistant courses cover CPR, infection control, vital signs, range of motion, terminology, anatomy, patient rights, ethics and communication skills, which are critical to caring for patients and interacting with health care professionals. This basic knowledge is taught in an instructional environment and practiced with clinical training.
Certified nursing assistants work under the direct supervision of a registered nurse, licensed practical nurse or doctor.
