CNA Assisting with Range of Motion Exercises

Question 1

What is the primary purpose of range of motion (ROM) exercises?

Accepted Answer

Maintain joint flexibility and prevent contractures

Answer

Range of motion exercises are performed to maintain joint flexibility, prevent contractures (permanent joint tightening), and preserve muscle function in residents who have limited mobility.

Question 2

During passive range of motion exercises, who provides the force to move the joint?

Accepted Answer

The CNA moves the resident's joints for them

Answer

In passive ROM exercises, the CNA moves the resident's joints through their range of motion because the resident is unable to do so independently. No effort is required from the resident.

Question 3

A resident cries out in pain during a ROM exercise. What should the CNA do immediately?

Accepted Answer

Stop the exercise immediately and report to the nurse

Answer

If a resident experiences pain during ROM exercises, the CNA must stop immediately and report to the nurse. Pain signals possible injury or a condition that needs medical evaluation.

Question 4

How far should a CNA move a resident's joint during passive ROM exercises?

Accepted Answer

Only to the point of resistance or slight discomfort

Answer

ROM exercises should only be performed to the point of resistance or slight discomfort — never to the point of pain. Forcing a joint beyond its comfortable range can cause injury.

Question 5

Which of the following is an example of a ROM exercise for the shoulder?

Accepted Answer

Abduction

Answer

Abduction — moving the arm away from the body — is a common shoulder ROM exercise. Dorsiflexion applies to the foot/ankle, pronation to the forearm, and inversion to the foot.
