The document discusses pain assessment and management for patients. It states that all patients expressing signs of pain must receive an appropriate assessment and treatment. Pain is best determined by the patient as pain measurement is subjective. Patients should receive a comprehensive pain assessment upon arrival that examines onset, duration, location, quality, relief factors, aggravating factors, pain goal, and intensity using a standardized scale. Patients must be reassessed after any pain interventions like medications or other treatments to determine the effectiveness of the treatment.
