A nurse is assisting a client during ambulation when the client begins to fall. Which of the following actions should the nurse take?

The correct answer is D: Lower the client to the floor. This is the safest action to prevent injury during a fall. Lowering the client to the floor minimizes the distance they fall, reducing the risk of serious injury. Assuming a narrow base of support (A) may lead to the nurse losing balance. Leaning the client toward the wall (B) may not effectively prevent a fall and could cause injury. Providing support by holding the client's arm (C) may not be enough to prevent a fall or injury. Lowering the client to the floor (D) is the best option as it prioritizes the client's safety and minimizes the risk of injury.
