A nurse is assessing pain in a 4-year-old child who is nonverbal following a surgical procedure. The child is grimacing, has rigid legs, and is inconsolable. Which pain assessment tool is most appropriate for this patient, and why?
- Wong-Baker FACES scale, because it uses images the child can point to for self-report
- CRIES scale, because it is designed for neonates from birth to 6 months
- Numeric Rating Scale (NRS), because it is standardized for all pediatric patients
- FLACC scale, because it is designed for nonverbal children from 2 months up to 7 years
