A nurse is assessing the pain of an 8-year-old child using the numerical pain scale. Which of the following questions should the nurse ask the child?

Rationale: A. Asking the child to touch a face corresponds to the FACES pain scale, not the numerical scale. B. Asking about behavioral changes provides observational data but does not give a self-reported numeric pain rating. C. Asking the child to rate pain on a scale from 0 to 10 is appropriate for the numerical pain scale, which is validated for children around 8 years old who can understand and quantify their pain numerically. D. Describing pain with words such as none, a little, medium, or a lot corresponds to a verbal descriptor scale, not the numerical scale.
