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 FLACC (Faces, Legs, Activity, Cry, Consolability) pain scale is ideal for assessing pain in toddlers, especially those who are cognitively impaired. It relies on observable behaviors rather than self-report. B. A visual analog scale requires the patient to rate pain on a linear scale, which is not suitable for a toddler, especially one who is cognitively impaired. C. While the FACES pain scale is useful for older children who can understand facial expressions, it is not appropriate for toddlers, especially those with cognitive impairments. D. The CRIES pain scale is primarily used for neonates, not toddlers.
