What letter is scored on the AVPU scale if a patient only responds after loud stimuli?

The AVPU scale is a simple method used to assess a patient's level of consciousness. The letters stand for Alert, Verbal response, Pain response, and Unresponsive. In the context of this question, if a patient only responds after loud stimuli, they are categorized under "P" for Pain response.

This means that the patient is not alert or responding to verbal commands but will exhibit some response when subjected to a painful or loud stimulus. It indicates a decreased level of consciousness compared to an alert individual who would respond spontaneously. The responses on the AVPU scale help healthcare providers establish the severity of a patient's condition and determine the appropriate level of intervention required.

In summary, recognizing that a patient who requires loud stimuli to respond falls into the "P" category helps in evaluating their state and planning further medical assessment.
