Medical Terminology / Unit 4 MedTerm 0207 short lesson, about 20 seconds
Error: Using Directional Terms From the Viewer's Position
Captions available
The idea
Directional terms describe the patient's body, never the position of the person looking at it.
In practice
A lesion on the patient's left appears on the viewer's right, and is recorded as left.
Where people slip
This error reverses sides in a record, which is how procedures reach the wrong limb.
