The gold standard of pain assessment is the report of pain by patients who are capable of doing so (APS, 2008; McCaffery, Herr, & Pasero, 2011). A comprehensive assessment includes the patient’s description of the pain, including its location, duration, what aggravates and relieves it, and its intensity. Pain intensity is rated by the patient using a reliable and valid pain assessment tool, such as the 0 to 10 numerical pain rating scale (NRS), Wong-Baker FACES scale, or the Faces Pain Scale-Revised (FPS-R) (www.painsourcebook.ca) (McCaffery, Herr, & Pasero, 2011). Some patients prefer a verbal descriptor scale (VDS), which uses words that correlate with the NRS, such as no pain (0), mild pain (1-3), moderate pain (4-6), or severe pain (7-10).
