CNA Certification (Written Exam)Restorative SkillsEasy
A CNA is assisting a resident with passive range of motion (PROM) exercises for their elbow. Which movement demonstrates proper elbow flexion?
- ABending the arm so the hand moves towards the shoulder.
- BStraightening the arm completely away from the body.
- CMoving the arm in a circular motion at the shoulder joint.
- DRotating the forearm clockwise and counter-clockwise.
Show answer & explanationAnswer & explanation
Correct answer: A. Bending the arm so the hand moves towards the shoulder.
Elbow flexion involves bending the arm, which brings the hand closer to the shoulder. This movement reduces the angle between the upper arm and forearm.
Why the other options are wrong
- B. This describes elbow extension, which is the opposite of flexion.
- C. This describes shoulder rotation, not elbow movement.
- D. This describes pronation and supination of the forearm, not elbow flexion.
Elbow Flexion
The movement that decreases the angle between the forearm and the upper arm, bringing the hand closer to the shoulder.
- Part of passive range of motion (PROM) exercises.
- Essential for daily activities like eating and grooming.
- Performed by bending the arm at the elbow.
Memory trick: Flex means bend, extend means straighten.
