What does the AVPU scale assess?

• A. Level of consciousness
• B. Blood pressure
• C. Respiratory rate
• D. Body temperature

Answer: (A)

The AVPU scale assesses level of consciousness by grading a patient’s responsiveness into four categories: Alert, responds to Voice, responds to Pain, and Unresponsive. This quick bedside check tells you how awake and mentally responsive the patient is, which helps you track neurological status over time and decide immediate actions. In practice, you first see if the person is fully awake and oriented (Alert). If not, you test for response to spoken commands (Responds to Voice). If there’s still no response, you apply a painful stimulus (Responds to Pain) to see if there’s any reaction. If there’s no response to pain, the patient is Unresponsive. This assessment is distinct from vital signs like blood pressure, respiratory rate, or body temperature and is especially useful in emergencies to prioritize care and monitor for changes in consciousness.
