Why do people fail range of motion and positioning on the CNA skills test?
Updated · Reviewed against official sources
Range of motion fails when you don't support the joint above and below, do fewer repetitions than the checklist requires (at least three on Credentia's lists), keep going after the resident reports pain, or practice the wrong joints — Credentia tests one knee and ankle or one shoulder, Prometric tests elbow and wrist, shoulder, or hip, knee and ankle, and Ohio tests hip and knee or shoulder. Positioning fails on body alignment, pillows and the final safety checks.
| Vendor | ROM skills |
|---|---|
| Credentia | One knee and one ankle; one shoulder |
| Prometric (TX, FL) | One elbow and wrist; one shoulder; one hip, knee and ankle |
| D&S Headmaster (OH) | Hip and knee; shoulder |
Fixes
- Support the limb at the joint for every movement.
- Count repetitions out loud.
- Ask about pain before and during; stop if it hurts.
- Positioning: align the body, support with pillows as your checklist states, then bed low and call light in reach.
