Which of the following methods is most effective for a nurse to assess pain in a 4-year-old child?

A. Descriptive words might be confusing for a 4-year-old and may not accurately capture their experience of pain. B. The faces pain scale is effective for young children as it uses visual cues that they can relate to, making it easier for them to express their pain level. C. While observing the child’s behavior can provide insights, it does not give a direct assessment of pain. D. Rating pain on a scale of one to ten may be difficult for a child this age, as they may not fully understand numerical values.
