Planning a preventive schedule of pain medication around the clock ensures consistent pain relief and better management. Giving the child a clock and explaining when they can have pain medications may increase the child's focus on waiting for relief rather than addressing the pain promptly, making it a less effective strategy.

A respiratory rate of 24 breaths per minute (choice D) is slightly elevated but may not be as concerning as a heart rate of 120 beats per minute.
