A nurse is caring for a client who has become aggressive and requires the placement of wrist restraints to maintain the client's safety. Which of the following actions should the nurse take?

A. Observe the circulation of the client's extremities: Regularly assessing the neurovascular status of restrained extremities is critical to ensure that the restraints are not compromising blood flow or causing tissue injury. The nurse should check for color, temperature, pulse, capillary refill, and sensation frequently to maintain client safety. B. Use square knots to secure the client's restraint: Restraints should be secured using quick-release knots rather than square knots, allowing the nurse to remove them quickly in an emergency. Square knots are difficult to untie and can delay rapid intervention if complications arise. C. Tie the restraint to the rail of the client's bed: Restraints should never be tied to moveable parts of the bed, such as rails, because this can cause injury if the bed is adjusted. Restraints should be secured to a stationary part of the bed frame to prevent entanglement or injury. D. Obtain the client's vital signs every 4 hr: When a client is restrained, vital signs should be monitored more frequently than every 4 hours, typically every 15–30 minutes initially, to detect changes in condition or signs of distress. Less frequent monitoring does not ensure early identification of complications.
