More about these tools
A caregiver is reading a manual that names pieces the box never mentioned. Each page is one drawing of one device, with a numbered ring on every part. Open Study to read each name and what the part does, then switch to Find it or Name it, and missed parts return at the end of the round. Every drawing prints blank or labeled.
These pages are vocabulary aids. They name parts and stop there, with nothing on using, fitting, cleaning or choosing a device. Your instructor, your clinician and the maker's manual cover that. Every name was checked against two references on the date its page shows, and no maker's model or mark is drawn.
