Final answer:
A score of '2' on the child's facial expression on the FLACC scale suggests that the child is experiencing severe pain.
Step-by-step explanation:
The FLACC scale is a behavioral scale used to assess pain in children who are unable to communicate their pain verbally. The 'F' in FLACC stands for 'Face'. If a child's facial expression is scored as '2' on the FLACC scale, it indicates that the child's facial expression shows that they are experiencing severe pain. The FLACC scale scores range from 0 to 10, with each of the five categories (Face, Legs, Activity, Cry, Consolability) being scored from 0 to 2. A score of '0' means 'no pain' and '2' suggests the pain is at its worst as per that specific category.
