Alternatives always come before restraints
The exam's default position is that restraint is the last option. Correct answers first exhaust alternatives: frequent orientation and reassurance, moving the client nearer to the nurses' station, involving family or a sitter, providing adequate lighting and familiar objects, meeting toileting, pain, hunger and thirst needs proactively, using bed and chair alarms, lowering the bed and using floor mats, and reviewing medications that may contribute to delirium.
Distraction and environmental modification matter as much as observation. A confused client pulling at an intravenous line may respond to a long sleeve or an abdominal binder covering a feeding tube, to activity such as folding towels, or to reduced noise and clutter. Any of these appearing as an answer choice will usually outrank a restraint option.
Restraints are justified only when the client presents an immediate danger to self or others and less restrictive measures have failed. They are never used for staff convenience, as punishment, or as a routine response to confusion. Recognizing an inappropriate rationale in the stem is often the entire point of the question.
Orders, time limits and the emergency exception
A restraint requires a provider order that specifies the type of restraint, the specific behaviour or clinical justification, and a time limit. Standing orders and PRN orders are prohibited. When restraint is applied in an emergency to prevent immediate harm, the nurse may act first, but an order must be obtained promptly, usually within one hour, and the provider must perform a face-to-face evaluation of the client within that hour for violent or self-destructive restraint.
Time limits depend on the reason. For violent or self-destructive behaviour, orders are limited to four hours for adults eighteen and older, two hours for children and adolescents aged nine to seventeen, and one hour for children under nine, with renewal required after reassessment. Non-violent medical-surgical restraint used to protect a therapeutic device is renewed at least every twenty-four hours after in-person reassessment.
The order must be renewed based on a new assessment, not automatically. Discontinuation happens as soon as the client meets release criteria, and the exam expects continual reassessment of whether the restraint is still needed rather than waiting for the clock to run out.
| Situation | Order duration | Monitoring frequency |
|---|---|---|
| Violent, adult 18+ | Up to 4 hours | At least every 15 minutes |
| Violent, ages 9–17 | Up to 2 hours | At least every 15 minutes |
| Violent, under 9 | Up to 1 hour | At least every 15 minutes |
| Non-violent medical restraint | Renew every 24 hours | Per policy, commonly every 1–2 hours |
| Emergency application by nurse | Order within 1 hour | Continuous initial observation |
Safe application and monitoring
Application technique carries several near-certain test points. Restraints are secured with a quick-release knot to the movable portion of the bed frame so the tie moves with the bed, never to the side rail and never to a fixed frame. Two fingers should slide easily beneath the restraint. The limb is placed in a natural anatomical position, padding protects bony prominences, and the call light stays within reach of the free hand.
Monitoring for violent restraint includes checks at least every fifteen minutes covering circulation, colour, temperature, sensation and movement distal to the restraint, skin integrity, correct placement, respiratory status and signs of distress. Restraints are released at least every two hours for range of motion, repositioning, skin care, toileting, fluids and nutrition, and one limb is released at a time in an agitated client.
Position matters for safety. A restrained client is never left in a supine position with the head flat if aspiration risk exists, and vest restraints in particular carry an asphyxiation risk if the client slides. Never leave a restrained client alone in a room with the door closed when seclusion has not been ordered, and never restrain a client to a chair that can tip.

- •Two fingers must fit beneath the device
- •Neurovascular checks distal to every restrained limb
- •Release every 2 hours for range of motion, skin care and toileting
- •Call light and fluids within reach at all times
- •Reassess for the earliest safe discontinuation each check
Documentation, seclusion and delegation
Documentation must show the whole decision trail: the behaviour that necessitated restraint, the alternatives attempted and their outcome, the client and family notification and education, the order details, the type and location of restraint, every monitoring check, care provided during releases, the client's response, and the criteria and time of discontinuation. An incomplete record is treated as though the care did not occur.
Seclusion is the involuntary confinement of a client alone in a room they cannot leave, and it is used only for violent or self-destructive behaviour with the same order and monitoring requirements as violent restraint. Continuous visual observation is required. A client in seclusion cannot be simultaneously restrained without additional justification and continuous face-to-face monitoring.
Delegation questions appear frequently. Assistive personnel may check on a restrained client, provide fluids, assist with toileting, reposition and report observations, but the registered nurse retains assessment of skin integrity and neurovascular status, evaluation of continued need, and all documentation of assessment. Deciding to apply or discontinue a restraint is never delegated.
