A 11-year-old with no past medical history presents with appendicitis. Which pain scale is most appropriate to use:

A. Wong-Baker Faces Pain Rating Scale: This scale is typically used for younger children who may have difficulty quantifying pain numerically. An 11-year-old generally has the cognitive ability to understand and use more precise self-report tools, making this scale less appropriate. B. Pain is objective, thus does not usually require using a pain scale: Pain is a subjective experience and must be assessed using standardized tools for accurate evaluation and management. Relying on observation alone can lead to underassessment and inadequate pain control. C. Visual Analog Scale: numerical 1–10: School-aged children and adolescents can reliably self-report pain using numeric scales. The 1–10 scale allows for more precise assessment of pain intensity, aiding in appropriate analgesic management and monitoring response to treatment. D. FLACC pain score: The FLACC scale is designed for infants or children who are unable to communicate their pain verbally. An 11-year-old can self-report pain effectively, making this observational tool unnecessary in this situation.
