1. Rapid Summary
Restraints (physical or chemical) are devices or medications used to restrict a client's movement or manage behavior. They are an intervention of absolute last resort, used strictly to protect the client or others from immediate physical harm. Restraints must never be used for staff convenience, punishment, or as a substitute for adequate supervision. The core principle of restraint safety is utilizing the least restrictive environment possible.
2. High-Yield Points/Must Know
| Priority Action | Essential Guideline |
|---|---|
| Exhaust Alternatives First | Always attempt and document non-restrictive measures (e.g., reorientation, bed alarms, sitters, moving the client closer to the nurse's station) before applying restraints. |
| Strict Prescription Rules | A provider must conduct a face-to-face assessment. Prescriptions must state the reason, type, location, and duration. |
| Attachment Point | Always tie restraints to a movable part of the bed frame that moves with the client. Never tie them to the side rails. |
| Knot Type | Always use a quick-release knot (slipknot) or buckle that can be removed rapidly in an emergency. |
| Space Requirement | Ensure you can fit exactly two fingers between the restraint and the client's skin to prevent neurovascular compromise. |
3. Mnemonics
Remember the REST protocol for caring for a restrained client:
- R - Release the restraint every 2 hours (or per facility policy) to provide range of motion (ROM).
- E - Evaluate the ongoing need for the restraint continuously. Discontinue as soon as possible.
- S - Skin & Sensation checks (Neurovascular assessment) every 15-30 minutes.
- T - Toilet, hydrate, and provide nutrition every 2 hours.
4. Most Tested Facts
Time Limits for Behavioral Restraint Prescriptions (Age-Dependent):
| Client Age | Maximum Duration per Prescription |
|---|---|
| Adults (18+ years) | 4 Hours |
| Children & Adolescents (9-17 years) | 2 Hours |
| Children (Under 9 years) | 1 Hour |
- The "No PRN" Rule: There is never a valid PRN (as needed) order for a restraint. A new prescription is required every single time a restraint is applied or after the time limit expires.
- Side Rails: Having all 4 side rails up is considered a physical restraint, except in very specific circumstances (e.g., seizure precautions, during transport).
5. Clinical Correlation
A 78-year-old client with delirium secondary to a UTI is pulling at their IV line.
- Wrong Action: Immediately applying bilateral soft wrist restraints.
- Correct Action: First, attempt alternatives. Hide the IV line under a long-sleeved gown (camouflage), give the client a washcloth to hold (distraction), or ask a family member to sit with them. If these fail and the IV is life-sustaining, restraints may be considered after obtaining a specific provider order.
6. Frequently Tested
Neurovascular Assessment (CMS Checks):
You will frequently be tested on what to assess after applying a limb restraint. You must check CMS every 15–30 minutes:
- C - Circulation: Capillary refill (< 3 seconds), skin color, temperature, peripheral pulses.
- M - Motor: Ability to move the fingers/toes distal to the restraint.
- S - Sensation: Checking for numbness, tingling, or pain.
Documentation Requirements:
If a restraint is applied, documentation must be exhaustive: behavior precipitating the restraint, alternatives attempted and their failure, time of application/removal, type of restraint, and routine care (hydration, toileting, ROM).
7. Common NCLEX Trap
- Trap: An order reads "Apply soft wrist restraints PRN for agitation."
- Reality: False. PRN restraint orders are illegal in nursing practice.
- Trap: The nurse loosens the restraints and ties them to the side rail to give the patient more room to move.
- Reality: False. Tying to a side rail can cause severe injury (dislocation or fracture) if the rail is lowered unexpectedly. Always use the bed frame.
- Trap: In a multiple-choice question, "Apply a restraint" is an option to keep a wandering dementia patient safe.
- Reality: False. Wandering is not an indication for restraints. Use a bed alarm or place the patient in a room near the nurse's station.
8. Mini Questions
Question 1: A nurse receives a telephone order from a physician to apply bilateral wrist restraints to a combative patient, stating, "I will assess the patient and sign the order tomorrow morning." What is the nurse's best action?
A. Apply the restraints and ensure the physician signs the order within 24 hours.
B. Inform the physician that a face-to-face assessment must be completed within 1 hour.
C. Apply the restraints but document that the physician refused to assess the patient.
D. Wait until the physician arrives tomorrow to apply the restraints.
- Answer: B
- Explanation: For behavioral restraints in an emergency, an RN may apply the restraint to protect safety, but the provider must conduct a face-to-face assessment within 1 hour of application. Waiting until tomorrow is a violation of restraint protocols.
Question 2: Which of the following non-pharmacological interventions should the nurse attempt before requesting a restraint order for a confused older adult trying to get out of bed? (Select all that apply)
A. Raise all four side rails.
B. Provide a folding towel for the client to hold.
C. Activate a bed-exit alarm.
D. Administer a prescribed dose of lorazepam.
E. Move the client's room closer to the nursing station.
- Answer: B, C, E
- Explanation: Distraction (towel), alarms, and closer supervision are excellent least-restrictive alternatives. Raising 4 side rails is a physical restraint. Lorazepam is a chemical restraint.
Question 3: The nurse is caring for a 14-year-old client placed in physical restraints due to aggressive, self-harming behavior. The nurse knows the provider's restraint order must be renewed at which interval?
A. Every 1 hour
B. Every 2 hours
C. Every 4 hours
D. Every 24 hours
- Answer: B
- Explanation: For clients aged 9 to 17, the maximum duration for a behavioral restraint prescription is 2 hours.
Question 4: The nurse is assessing a client in bilateral wrist restraints. Which finding requires immediate intervention?
A. Capillary refill is 2 seconds in the fingers.
B. The nurse can slide two fingers between the restraint and the client's wrist.
C. The client's hands are cool to the touch and slightly pale.
D. The restraints are tied to the movable portion of the bed frame.
- Answer: C
- Explanation: Cool, pale skin distal to the restraint indicates compromised circulation (neurovascular impairment) and requires immediate removal/adjustment of the restraint and reassessment.
Question 5: A client with a traumatic brain injury is pulling at their nasogastric (NG) tube. The nurse applies mittens to the client's hands. Are the mittens considered a restraint?
A. No, because they are not tied to the bed.
B. Yes, because they restrict the client's freedom to use their hands and access their body.
C. No, because they are being used for a medical necessity.
D. Yes, but they do not require a provider's prescription.
- Answer: B
- Explanation: Any device that prevents the client from moving freely or accessing their own body (like mittens that prevent grabbing) is considered a physical restraint and requires a strict provider prescription and monitoring.

9. Key Takeaway Box
Key Takeaway: Restraints are ALWAYS a last resort. You must memorize the strict time limits based on age (Adults: 4h, 9-17: 2h, <9: 1h), never accept a PRN order, always try alternatives first, tie to the bed frame using a quick-release knot, and ensure a two-finger gap for safety. Protect the airway, check circulation every 15-30 minutes, and release every 2 hours!
