Which statement about the Pain Scale is true?

• A. It Quantifies Patient Pain Levels
• B. It Is Used to Measure Blood Pressure
• C. It Helps Assess Severity of Pain by Assigning a Numeric Score
• D. It Replaces Physician's Diagnosis

Answer: (C)

Pain scales turn a patient’s report of pain into a numeric score so clinicians can gauge how severe it is and track changes over time. This is why describing it as helping assess severity by assigning a numeric score fits best: the score translates subjective pain into a concrete number that guides decisions about treatment and monitoring. It isn’t used to measure blood pressure, and it doesn’t replace a physician’s diagnosis—it's a standardized way to quantify pain to inform care.
