A nurse is caring for a 2-year-old toddler who is postoperative and nonverbal due to sedation. The child is grimacing and pulling at their IV site. Which pain assessment tool is MOST appropriate?

A. This scale uses a series of faces ranging from a happy face (no pain) to a crying face (worst pain) and requires the child to identify which face best represents their pain level. It is suitable for children approximately 3 years and older who are verbal and cognitively able to associate facial expressions with their own pain. A sedated, nonverbal 2-year-old cannot reliably communicate using this method, making it inappropriate. B. This scale asks the patient to rate their pain on a scale of 0 to 10. It requires verbal communication, abstract thinking, and the ability to quantify pain, which toddlers, especially a sedated 2-year-old, are unable to do. Therefore, this scale is not suitable in this context. C. FLACC (Face, Legs, Activity, Cry, Consolability) is specifically designed for infants and young children (typically 2 months to 7 years) who are nonverbal or unable to self-report pain. It relies on observable behaviors, making it the most appropriate tool for a sedated postoperative toddler. D. This scale asks the patient to mark a point on a line that represents their pain intensity from “no pain” to “worst pain.” It requires cognitive understanding, fine motor skills, and self-reporting, making it inappropriate for a sedated toddler who cannot comprehend or mark the scale.
