Final answer:
Pain assessment criteria include subjective self-report scales and objective physiological measures. The Wong-Baker Faces pain-rating scale and measuring skin conductance fluctuations are two common methods.
Step-by-step explanation:
Pain assessment criteria are used to evaluate and measure the intensity and severity of pain. There are several methods and tools for assessing pain, including subjective self-report scales and objective physiological measures.
One widely used pain assessment tool is the Wong-Baker Faces pain-rating scale, where patients rate their pain on a scale of 0-10 using facial expressions. Another method is measuring skin conductance fluctuations, which reflect sweating due to pain-related stress.
