COWS is used to determine whether a patient is conscious and responding. Which sequence correctly represents COWS?

• A. Can you hear me? Open your eyes? What's your name? Squeeze my hand
• B. Squeeze my hand
• C. Open your eyes
• D. Can you hear me? What's your name? Squeeze my hand? Open your eyes

Answer: (A)

Testing consciousness in a stepwise, escalating way starts with a simple, reliable signal and builds up to more complex responses. Begin by addressing the patient to see if they can hear you, which tells you they’re awake enough to process sound. Next, ask them to open their eyes to verify they respond to stimulation and are not just mutely unresponsive. Then check orientation and verbal ability by asking for their name, which assesses whether they can follow simple information and speak clearly. Finally, request a purposeful motor task, like squeezing your hand, to confirm they can execute a voluntary movement. This sequence—can you hear me, open your eyes, what's your name, squeeze my hand—follows the natural progression from basic arousal to orientation to purposeful action, making it the best representation of how to assess consciousness and responsiveness. Other sequences that skip steps or jump straight to a motor command can miss whether the patient is truly responsive at a basic level.
