Which tool is commonly used to evaluate a patient's pain intensity on a scale from 1 to 10?

• A. Visual analog scale
• B. Numeric rating scale
• C. 1-10 Pain Scale
• D. Wong-Baker FACES Pain Rating Scale

Answer: (C)

Pain intensity is most effectively captured with a simple numeric rating—asking the patient to assign a number that reflects their pain on a 1 to 10 scale. This 1-10 approach (the numeric rating scale) is used widely because it’s quick, easy to administer, and provides a straightforward, reproducible way to track changes in pain over time. A lower number meaning mild pain and a higher number indicating severe pain lets clinicians gauge response to treatment and adjust plans accordingly. Other tools exist for different contexts—like a line-based visual analog scale or a faces scale—but for fast, standardized quantification of pain intensity, the 1-10 scale is the most commonly used.
