Which item is sometimes listed as a fifth vital sign?

• A. Pain
• B. Temperature
• C. Blood pressure
• D. Heart rate

Answer: (A)

Pain is included as a fifth vital sign because it captures the patient’s subjective experience of discomfort, which directly affects healing, function, and safety. While the traditional four vital signs—temperature, pulse (heart rate), respiration, and blood pressure—are objective measurements, pain is reported by the patient and can change with treatment. Regularly assessing pain with a standardized scale (like 0–10 or a faces scale) helps clinicians identify distress early, document it consistently, and gauge how well analgesia is working. Some settings also track oxygen saturation as an additional indicator, but pain is commonly listed as the fifth vital sign due to its critical impact on comfort and recovery.
