Radiography | A general term for procedures that use roentgen rays, or X-rays, produces images of body structures. |
Radionuclides | Elements whose molecular structures are altered to produce radiation. |
Roentgenography | A general term for procedures that use roentgen rays, or X-rays, produces images of body structures. |
Sim's position | The client lies on the left side with the chest leaning forward, the right knee bent toward the head, the right arm forward, and the left arm extended. (rectal , vaginal, rectal temp assessment) |
