The RASS is a 10-point scale ranging from -5 to +4. A score of 0 indicates a patient is alert and calm. Scores from -1 to -5 represent varying levels of sedation, with -1 being drowsy and -5 indicating unarousable. Scores from +1 to +4 indicate levels of agitation, with +1 being restless and +4 denoting combative. The scale helps nurses tailor sedation needs by assessing patient response and adjusting medications accordingly.
