What is the primary goal of Range of Motion exercises?

1. To increase a resident's aerobic fitness

2. To prevent joint contractures and muscle atrophy

3. To promote weight loss in sedentary residents

4. To improve a resident's mental health

The correct answer is: To prevent joint contractures and muscle atrophy

The primary goal of Range of Motion (ROM) exercises is to prevent joint contractures and muscle atrophy. These exercises involve the intentional movement of joints and muscles through their full range to maintain flexibility, strength, and function, particularly in individuals who may be immobile or have limited movement due to illness or injury. By regularly performing ROM exercises, caregivers can help prevent the shortening of muscles and tendons that can lead to contractures, a condition where joints become stiff and lose their normal range of motion. Additionally, these exercises help combat muscle atrophy, which is the wasting away of muscle tissue due to inactivity. This is crucial for maintaining mobility and independence for residents, making it a vital aspect of patient care. While other options mention fitness, weight loss, and mental health, ROM exercises specifically target the physical maintenance of joints and muscles, thereby directly addressing the issues of contractures and atrophy.
