How can a nurse best support an older adult at risk for falls?

Supporting an older adult at risk for falls involves creating a safe environment and promoting their independence while minimizing hazards. Locking the bed and wheelchairs provides stability and prevents accidental movement, which could lead to falls. Keeping call lights within reach encourages the patient to ask for assistance when needed, thereby promoting safety and reducing the likelihood of falls that may occur when they try to get up unassisted.

The other options could inadvertently increase the risk of falls or do not effectively prioritize the patient's safety. Encouraging frequent movement without proper supervision or assistance might lead to instability. Placing the patient far from the nurses' station could hinder quick access to help, and limiting fluid intake is not a safe strategy since it can lead to dehydration and other complications. Overall, option C embodies a comprehensive approach to minimizing fall risks by ensuring safety measures and promoting communication and support.
