A nurse is caring for a 5-year-old child who is postoperative following a tonsillectomy. Which of the following pain scales should the nurse use to determine the child's pain level?

Choice A rationale The FACES pain scale is appropriate for a 5-year-old child because it uses a series of illustrated facial expressions, ranging from happy (no pain) to crying (worst pain), allowing the child to visually identify the face that best represents their pain intensity without requiring abstract numerical understanding. Choice B rationale The Visual Analog Scale (VAS) requires the child to mark a point on a continuous line, which is an abstract concept that often proves too complex for a 5-year-old child due to their developmental stage and limited understanding of numerical or spatial gradients. Choice C rationale The FLACC (Face, Legs, Activity, Cry, Consolability) pain scale is primarily used for non-verbal or pre-verbal children, or those with cognitive impairments, as it relies on observational behavioral cues rather than self-report, making it less ideal for a 5-year-old who can communicate. Choice D rationale The Oucher pain scale uses a series of photographs of children's faces depicting varying pain levels, along with a numerical scale. While it incorporates visual cues, the numerical component might still be challenging for some 5-year-olds, and the FACES scale is often more universally understood by this age group.
