V- is the person verbal or nonverbal. If they are verbal, is the communication appropriate or unappropriate for the situation? Do they make sense when they speak or are they mumbling or speaking about irrelevant events?
P- pain. Does the person respond to painful stimuli if they are not alert? When you pinch their arm or twist the nipple do they make any response at all?
U-unresponsive. If they are unresponsive are they moving at all or completely flaccid. Do they exhibit any purposeful movement at all? Are they having a seizure or showing any posturing?
