A nurse is evaluating the pain level of a toddler who is cognitively impaired to a non-pharmacologic intervention. Which of the following pain scales should the nurse use to evaluate the toddler's pain level?

A. The CRIES scale is more suitable for assessing pain in neonates. B. The FACES scale is often used for children who can understand and express their pain with facial expressions; it is not ideal for cognitively impaired toddlers. C. The Visual analog scale is typically used for older children who can understand the concept of pain intensity. D. The FLACC scale (Face, Legs, Activity, Cry, Consolability) is appropriate for assessing pain in non-verbal or cognitively impaired toddlers as it evaluates behaviors that indicate discomfort.
