A 5-year-old child is scheduled for a vaccination. The nurse wants the child to self-report pain. The child can understand pictures but has difficulty with numbers. Which pain assessment tool is MOST appropriate?

A. This scale requires the child to understand numbers and quantify pain. A 5-year-old who has difficulty with numbers cannot reliably use this scale, making it inappropriate. B. While FLACC is excellent for observational assessment of nonverbal or pre-verbal children, it does not allow the child to self-report pain. Since the nurse wants the child to self-report, this is not the best choice. C. This scale requires the child to mark a point on a line representing their pain intensity. It also requires abstract thinking and fine motor skills, which may be challenging for a 5-year-old, especially if they can’t reliably understand numbers or gradients. D. The Oucher scale uses pictures of faces showing increasing pain intensity along with a numeric scale. For children who understand pictures but struggle with numbers, this scale allows them to self-report pain by pointing to the face that matches their discomfort. It is validated for children aged 3–12 years, making it the most appropriate choice for a 5-year-old who can use pictorial cues.
