Which tool is used to screen alertness and ability to follow commands in ICU patients?

• A. Richmond Agitation-Sedation Scale (RASS): range -1 to +1; negative indicates sedation, 0 = alert and calm, positive indicates sedation
• B. Delirium Screening Tools: CAM-ICU, Intensive Care Delirium Screening Checklist, Nursing Delirium Screening Scale, Delirium Detection Score, Cognitive Test for Delirium
• C. Awakening criteria: can respond to 3-5 commands (open/close eyes, maintain eye contact, nod yes/no, open mouth and stick out tongue, and raise eyebrows on the count of 5)
• D. Nursing Delirium Screening Scale

Answer: (A)

The ability to quickly judge how awake and cooperative a patient is at the bedside is essential for deciding if they can follow commands or participate in therapy. The tool designed for this at the ICU is the Richmond Agitation-Sedation Scale. It provides a simple numeric readout of arousal from deeply sedated to agitated, with a score around zero indicating an alert and calm patient. This direct measure of wakefulness helps voice whether the patient can reliably respond to simple commands during assessments or treatments. Delirium screening tools and the described awakening criteria aim to assess later cognitive status or specific response tasks, but they depend on the patient already being sufficiently awake and attentive. If someone is heavily sedated, those tools can be unreliable or not applicable. The Richmond Agitation-Sedation Scale remains the quickest, most practical way to gauge alertness and the capacity to follow commands in the ICU setting.
