During knee ROM, which of the following is a key safeguard?

• A. Support leg, hold the knee and ankle.
• B. Slowly bend and straighten the knee through its range.
• C. Stop if pain occurs.
• D. Ensure proper alignment.

Answer: (C)

Pain during knee ROM is a warning sign that something may be injured or irritated. Stopping the motion as soon as pain occurs protects the joint and soft tissues from further harm and gives time to reassess, adjust the range, or pause the procedure as directed. While supporting the leg, moving slowly, and keeping proper alignment are important safeguards to prevent strain and ensure safe movement, the most important action is to halt if pain arises. This prevents worsening injury and prompts immediate evaluation by the supervising nurse.
