Use of Restraints in Nursing: Legal, Ethical, and Safety Principles

Restraints are one of the most heavily regulated nursing interventions because they directly limit a patient's freedom and carry real risk of physical and psychological harm. This note reviews the legal requirements, safe application, monitoring, and ethical principles that guide restraint use — all common exam targets.

Definition

A restraint is any device, method, or medication that restricts a patient's freedom of movement or normal access to their body. Restraints are used only as a last resort when less restrictive interventions have failed.

• The only acceptable purpose is to prevent imminent harm to the patient or others.
• Restraints are never used for staff convenience, punishment, or as a substitute for adequate staffing.

Types of Restraints

• Physical restraint — A device that limits movement.
  • Examples: wrist or ankle restraints, vest restraints, lap belts, all four side rails raised (when the patient cannot lower them).
• Chemical restraint — A medication (e.g., sedative or antipsychotic) given to control behavior rather than to treat a medical condition.
• Seclusion — Involuntary confinement of a patient alone in a locked room they cannot leave. Used only when the patient is a danger to others.

Legal and Regulatory Requirements

• Provider order required before applying restraints, except in a true emergency. In an emergency, the nurse may apply restraints first and obtain the order immediately afterward.
• Order time limits (maximum before renewal):
  • Adults: 4 hours
  • Children 9–17: 2 hours
  • Children under 9: 1 hour
• Face-to-face evaluation by the provider must occur within 1 hour of initiating restraints. Renewal requires a new face-to-face evaluation.
• Monitoring at least every 15 minutes.
• Documentation must include behavior, less restrictive measures attempted, interventions, and ongoing monitoring.

Less Restrictive Alternatives

Must be attempted and documented before restraints are applied.

• Environmental changes — reduce noise, dim lights, remove clutter, provide a calm atmosphere.
• Staff presence — one-to-one observation or a sitter.
• Diversion — activities, music, television.
• Family involvement — have a family member stay with the patient.
• Medication review — adjust or discontinue deliriogenic medications.
• Bed alarms — alert staff when the patient attempts to get up.
• Low beds — reduce fall height and injury risk.

Nursing Responsibilities

Before Applying Restraints

• Assess behavior, medical condition, and risk of harm.
• Attempt and document all less restrictive alternatives.
• Obtain a provider order (or in a true emergency, apply first and obtain order immediately).

During Restraint Use

• Apply per manufacturer instructions using the correct size.
• Secure to the bed frame, NOT the side rails.
• Ensure two fingers can fit between the restraint and the patient's skin.
• Use a quick-release knot for rapid removal in an emergency.
• Monitor at least every 15 minutes — assess circulation, skin integrity, vital signs, and comfort.
• Offer food, fluids, and toileting at regular intervals.
• Perform range of motion exercises every 2 hours.
• Remove restraints as soon as the patient is calm and no longer a danger.

After Restraint Removal

• Document the patient's behavior and any injuries.
• Debrief with the patient and family.
• Notify the provider.

Documentation Requirements

• The behavior that led to restraint use and all less restrictive alternatives attempted.
• Type of restraint, time applied, and provider order time.
• Monitoring findings every 15 minutes — skin, circulation, vital signs.
• Care provided — food, fluids, toileting, range of motion.
• Do NOT document “restraint applied to prevent falls.” Use “to prevent imminent harm.”

Ethical Considerations

• Restraints remove patient autonomy and liberty — use only when the benefit outweighs the loss of freedom.
• Physical harms: pressure injuries, nerve damage, contractures, and even death.
• Psychological harms: fear, humiliation, and worsening agitation.
• Never used for staff convenience, punishment, or to compensate for inadequate staffing.

Common Exam Traps

• Applying restraints without a provider order outside a true emergency.
• Forgetting time limits: 4 hr adults / 2 hr children 9–17 / 1 hr under 9.
• Securing restraints to side rails instead of the bed frame.
• A restraint that is too tight — must fit two fingers between restraint and skin.
• Using a knot that cannot be released quickly — must be a quick-release knot.
• Raising all four side rails without a provider order (counts as a restraint).
• Documenting “to prevent falls” instead of “to prevent imminent harm.”

Key takeaways

• Restraints are a last resort to prevent imminent harm — never for convenience or punishment.
• Order limits: 4 hours (adults), 2 hours (children 9–17), 1 hour (under 9); face-to-face evaluation within 1 hour.
• Always try and document less restrictive alternatives first (sitters, bed alarms, low beds, environmental changes).
• Secure to the bed frame, allow two fingers of space, use a quick-release knot, and monitor every 15 minutes.
• Document the indication as “to prevent imminent harm,” not “to prevent falls.”
• Remove restraints as soon as the patient is calm and safe.
