What Is the Purpose of Restraints in CNA Clinical Skills?

Updated September 30, 2026

The purpose of restraints is to protect a resident from immediate harm when less restrictive measures have failed. Restraints are never used for discipline, convenience, or coercion. In CNA clinical skills, you must understand that restraints are a last resort and require a doctor's order, ongoing monitoring, and frequent reassessment.

When Restraints May Be Used

Restraints may be appropriate only when a resident poses an immediate danger to themselves or others. Examples include:

  • A confused resident trying to climb out of bed and at risk of falling.
  • A resident pulling at a feeding tube or IV line, risking serious injury.
  • A resident exhibiting violent behavior that could harm staff or other residents.

Even then, federal regulations (CMS) require that restraints be used only after less restrictive alternatives have been tried and failed. Alternatives include redirection, pain management, toileting schedules, family involvement, and environmental changes.

Your Role as a CNA

As a CNA, you do not apply restraints independently. You may assist under a nurse's supervision, but you must:

  1. Check the resident frequently (at least every 15 minutes for circulation, breathing, and comfort).
  2. Release restraints regularly for range-of-motion exercises and toileting.
  3. Document everything: time applied, condition, and any changes.
  4. Report immediately if the resident shows signs of injury, numbness, or distress.

Never tie restraints to side rails or leave a resident unattended while restrained. Improper use can lead to serious injury, legal consequences, and loss of certification.

Key Takeaway

The purpose of restraints is safety, not punishment. Always advocate for the least restrictive option and follow your facility's policy.
