A physical, chemical, or environmental restraint is an intervention that limits a client's movement or controls behaviour for safety. A physical device may restrict a limb or trunk; a medication may function as a chemical restraint when its primary purpose is to control behaviour or movement rather than treat an identified condition; an environmental measure may restrict access or movement through the care setting. The label matters because restraint carries risks beyond the behaviour it is intended to control. Struggling can cause injury, impaired circulation, pressure damage, respiratory compromise, aspiration, or psychological trauma. The countermeasure is not simply closer observation after application. The nurse must first ask whether the danger can be reduced by treating its cause or by using a less restrictive intervention. Restraint is therefore a last-resort safety measure, not a response to inconvenience, staffing limitations, confusion alone, or a client's refusal to cooperate. It should be the least restrictive option that addresses the immediate risk and should remain in place only for the shortest duration necessary. A restraint is not a treatment for delirium, pain, hypoxia, urinary...
