Before leaving the room of a client who is confused, the nurse observes that a half bow knot was used to attach the client's wrist restraints to the movable portion of the client's bed frame. Which action should the nurse take before leaving the room?

A. Ensure that the restraints are snug against the client's wrists: Restraints should be snug enough to prevent injury but not so tight as to impair circulation. However, this does not address the safety concern related to the type of knot used. B. Move the ties so the restraints are secured to the side rails: Restraints should never be tied to the side rails because this can cause injury if the rail moves or the client attempts to climb over it. C. Ensure that the knot can be quickly released: Using a quick-release knot, such as a half bow or slip knot, is essential to ensure the nurse can rapidly remove the restraints in an emergency, such as sudden respiratory distress or circulatory compromise. D. Tie the knot with a double turn or square knot: Square knots are secure but not quick to release. In contrast, safety guidelines recommend quick-release knots for client restraints to allow for prompt intervention.
