Final answer:
The most accurate pain assessment technique for a 6-year-old child with burns on both hands is the Faces Pain Scale–Revised (FPS-R).
Step-by-step explanation:
For assessing the pain of a 6-year-old child with burns on both hands, the most accurate pain assessment technique would be the Faces Pain Scale–Revised (FPS-R). This scale uses a series of faces with different expressions to help the child identify and communicate their level of pain. It is a widely used and validated tool for pain assessment in children.
Option 1, the Numerical rating scale, may be difficult for young children to understand and accurately assign a numerical value to their pain.
Option 2, the Visual analog scale, relies on children's ability to mark a point on a line to represent their pain level, which may also be challenging for a 6-year-old.
Option 4, the Verbal descriptor scale, requires the child to describe their pain using words, which can be difficult for younger children who may not have a large vocabulary or difficulty expressing themselves verbally.
