A nurse is applying soft limb restraints to a child who is acting aggressively toward staff. Which of the following actions should the nurse take?

The correct answer is C: Secure the restraints with a quick-release knot. This is crucial for the safety of the child as quick-release knots allow for easy and immediate removal in case of emergency or if the child becomes distressed. Tying restraints to the side rails (A) could lead to injury if the child tries to get free. Requesting prescription renewal every 48 hr (B) is important but not the immediate action needed. Assessing the child every 4 hr (D) is essential, but securing the restraints with a quick-release knot takes priority for immediate safety.
