Before We Start
What is a restraint and when is it justified?
A physical restraint is any manual method or physical device that restricts a patient's freedom of movement or normal access to their body. This includes wrist restraints, mitt restraints, vest restraints, and even holding a patient down during a procedure.
A chemical restraint is a medication used to restrict behavior — sedatives given primarily to control behavior rather than to treat a medical condition.
Restraints are justified ONLY when the patient presents an imminent danger to themselves or others AND less restrictive alternatives have been tried and failed. The goal is always to use restraints for the shortest time possible while pursuing alternatives.
💡 The Two Indications for Restraints
1. Patient safety: Patient is at risk of harming themselves — pulling out an endotracheal tube, removing a PICC line or central line, picking at a surgical wound, or falling when confused and combative.
2. Danger to others: Patient is posing an imminent threat to staff or other patients.
NOT an indication: Staff convenience. Preventing falls (restraints do not effectively prevent falls). Punishment. Patient refuses to comply with treatment.
Before Restraints
Alternatives that must be tried first
The law requires that less restrictive alternatives be attempted before restraints can be applied. Document every alternative tried and why it failed before applying restraints.
Alternatives to try before restraints
• Reorientation and redirection: Calmly explain where the patient is and what the tubes/lines are for
• Sitter (1:1 supervision): A staff member or family member stays at bedside continuously
• Family presence: A familiar face often calms confused patients
• Environment modification: Dim lights, reduce noise, maintain normal day/night cycle
• Address underlying cause: Is the patient confused because of pain? UTI? Medication? Hypoxia? Treating the cause removes the behavior
• Move patient closer to nurses station: Increased visibility = increased supervision
• Mittens: Less restrictive than wrist restraints for patients picking at lines
• Bed alarm + lowest bed position: For patients attempting to get out of bed
• PRN medications: Anti-anxiety or antipsychotic medications prescribed by physician to reduce agitation
💊 Document every alternative tried before applying restraints: "Sitter requested — unavailable. Family contacted — unable to come. Patient reoriented x3 times within 30 minutes, continues to attempt ETT removal. Restraints applied per physician order at [time]."
Legal Requirements
What the law requires before, during, and after restraint use
Order Requirement
A physician or provider order is required — always
Restraints cannot be applied based on a verbal order and documented later — there must be a written or electronic order in place. Emergency situations allow for a brief period (30–60 minutes depending on facility policy) to obtain an order, but the order must be obtained as soon as possible.
What the order must specify:
• Type of restraint (wrist, mitt, vest)
• Clinical justification (specific behavior requiring restraint)
• Duration (time-limited — usually 24 hours maximum, must be renewed)
Applying restraints without an order = false imprisonment. This is a legal violation that can result in termination, loss of license, and criminal charges.
💊 No order = no restraints. Period. If you believe restraints are needed immediately, call the provider and get an order WHILE implementing alternatives. Never apply first and get the order later.
Monitoring Requirements
Every 30 minutes — neurovascular checks
Once restraints are in place, the nurse must check the patient every 30 minutes and document:
• Neurovascular status distal to the restraint (5 P's — Pain, Paresthesia, Paralysis, Pulse, Pallor)
• Skin integrity under and around the restraint
• Patient's behavior — is the restraint still needed?
• Patient's response to the restraint — is the patient calm or more agitated?
Apply the "two-finger rule": You should be able to slide two fingers between the restraint and the patient's skin. Too tight = neurovascular compromise. Too loose = patient can remove it.
💊 Document every 30-minute check — time, neurovascular findings, skin condition, patient behavior, and whether restraint remains necessary. If documentation stops, legally the monitoring stopped.
Release Schedule
Release every 2 hours — non-negotiable
Restrained patients must be released from restraints at minimum every 2 hours for:
• Repositioning (prevent pressure injuries)
• Range of motion exercises (prevent contractures and muscle atrophy)
• Toileting (prevent incontinence and urinary retention)
• Skin assessment (check for pressure injury or skin breakdown)
• Nutrition and hydration (offer food and water)
During the release period, maintain supervision. The patient does not become safe simply because the restraint has been temporarily removed.
💊 Release, reposition, ROM, toilet, assess skin — every 2 hours. Document each release with time, duration, activities performed, and patient response.
Application Rules
How restraints must be applied
• Tie to the bed frame — NEVER to the side rail. Side rails move; if the rail goes down, the restrained wrist goes with it — causing injury.
• Use a quick-release knot (clove hitch for wrists) that can be undone in seconds in an emergency
• Keep the restrained extremity in a functional position — neutral, not hyperextended
• Never restrain in the prone position — risk of suffocation
• Patient must be able to breathe freely — vest restraints must not restrict chest expansion
💊 Tie to bed FRAME, not side rail. Quick-release knot. Never prone. Two-finger rule. These four rules prevent restraint-related injury — and appear on NCLEX.
🏥 Clinical Scenario — ICU Patient Attempting to Remove ETT
Mr. Davis, 58 years old, intubated and mechanically ventilated in the ICU following cardiac surgery. He is lightly sedated, agitated, and repeatedly reaching for his endotracheal tube (ETT). Removal of the ETT would be immediately life-threatening.
1
Alternatives first: Increased sedation considered but not yet ordered. Reoriented x3. Family at bedside for 2 hours — still attempting to remove tube when family steps out. Mittens tried — patient removes them within 5 minutes. → Alternatives have failed.
2
Order obtained: Physician contacted at 1430. Bilateral soft wrist restraints ordered for "prevention of ETT removal — patient repeatedly reaching for tube despite alternatives." Order entered in EMR. Restraints applied at 1435.
3
Application: Clove hitch knots. Tied to bed frame, not rails. Two-finger rule confirmed bilaterally. Patient in supine position. Explained procedure to patient (he can hear even if he can't respond).
4
1500 check (30 min): Neurovascular intact bilaterally. Skin intact. Patient less agitated. Still pulling at restraints occasionally. Restraint remains necessary. Documentation completed.
5
1635 release (2 hour): Released one wrist at a time with nurse holding hand. Repositioned. Passive ROM x5 each joint. Offered water via syringe. Skin intact, no redness. Reapplied. Sedation reassessed with physician — dose adjusted. Plan: wean sedation, reassess restraint need at next check.
📌 NCLEX Application
Restraint questions appear consistently on NCLEX. Key facts:
• Restraints WITHOUT an order = false imprisonment (nurse liable)
• Improper restraint use causing harm = negligence
• Tie to BED FRAME, not side rail
• Quick-release knot — must be undoable in seconds
• Check every 30 minutes — neurovascular + skin + behavior
• Release every 2 hours — ROM, toilet, skin, nutrition
• Never restrain prone — risk of suffocation
• Two-finger rule — not too tight, not too loose
• Restraints do NOT prevent falls — wrong indication
NCLEX question pattern: "A nurse applies wrist restraints to a patient without an order to prevent the patient from falling. Which statement best describes this action?" → False imprisonment — the nurse has violated the patient's rights.
⚠️ The Two Legal Traps
Trap 1 — Applying restraints without an order:
Even if you genuinely believe the patient is in danger, applying restraints without an order is false imprisonment. Get the order first, or simultaneously while maintaining manual safety. Document every step.
Trap 2 — Tying to the side rail:
When the side rail is lowered (during care, during a transfer, during an emergency), the tied wrist goes with it — forcibly hyperextending or fracturing the wrist. This is a documented cause of restraint-related injury and is always wrong.
Always, always tie to the bed frame. It cannot be moved.
