What is the main purpose of performing range-of-motion (ROM) exercises with a resident?
- To maintain joint mobility and prevent contractures — Correct answer
- To increase the resident's body temperature
- To replace the need for the resident to walk
- To help the resident lose weight
Explanation: Range of motion (关节活动度/rango de movimiento) exercises move the joints to maintain joint mobility and prevent contractures (挛缩/contracturas). (Source: Self-Care/Independence — Restorative; OBRA-87)

What is a contracture?
- A joint that becomes stiff and permanently fixed from lack of movement — Correct answer
- A sudden, painless increase in a joint's flexibility
- A break or crack in a bone
- A temporary muscle cramp that goes away on its own
Explanation: A contracture (挛缩/contractura) is a joint that becomes stiff and permanently fixed because it has not been moved. ROM and positioning help prevent it. (Source: Self-Care/Independence — Restorative; OBRA-87)

How do contractures most commonly develop?
- From a joint not being moved for a long time — Correct answer
- From moving a joint too often during the day
- From drinking too much fluid
- From eating a high-protein diet
Explanation: Contractures (挛缩/contracturas) develop when a joint is not moved for a long time, so regular range-of-motion (关节活动度/rango de movimiento) and frequent position changes prevent them. (Source: Self-Care/Independence — Restorative; OBRA-87)
