What is the Richmond Agitation-Sedation Scale (RASS) used for?

• A. To measure agitation or sedation level
• B. To monitor blood glucose levels
• C. To determine lactate clearance
• D. To assess pain intensity

Answer: (A)

The main idea is measuring how awake, alert, or agitated a patient is. The Richmond Agitation-Sedation Scale provides a quick, standardized way to rate a patient’s level of agitation or sedation so clinicians can adjust medications safely. The scale covers a wide range—from deep sedation to active agitation—allowing bedside observers to assign a single score that guides titration of sedatives or analgesics, aiming for a target that keeps patients comfortable without oversedation. This helps reduce risks like delirium or prolonged ventilation.

The other options refer to different clinical measurements (blood glucose, lactate clearance, or pain intensity). RASS is specifically about agitation and sedation status, not those parameters.
