D. CUS (I am concerned, I feel uncomfortable, this is unsafe) is a communication tool for expressing concerns, for instance, by saying something like this: "I am concerned about the patient's risk for falls. I feel uncomfortable seeing you walk the patient without a gait belt or non-skid socks. This is unsafe for the patient and could cause harm or injury. Please use a gait belt and non-skid socks when walking the patient."
