Final answer:
Pain is assessed during the patient/client history using methods like numerical scales and skin conductance fluctuations. Other tools, like the broken end of a cotton-tipped applicator, can be used to test the perception of pain.
Step-by-step explanation:
Pain is assessed during the patient/client history through various methods. One common method is asking patients to rate their pain on a numerical scale, such as the Wong-Baker Faces pain-rating scale which asks patients to rate their pain on a scale of 0-10. Another method is measuring skin conductance fluctuations, which reflect sweating due to skin sympathetic nerve activity resulting from the stressor of pain. Additionally, clinicians may also use other tools to test the perception of pain, such as the broken end of a cotton-tipped applicator.
