The community nurse is assessing an elderly client who lives alone at home. the nurse finds that the client refrains from physical activity for fear of falling when walking. which interventions by the nurse are most beneficial to promote a healthy lifestyle?

Encourage the client to wear nonskid shoes (to prevent slipping), suggest that the client use an assistive device, help the client rearrange furniture in the house. 

It mainly depends on how the person feels motivated, you could maybe help them out during their activity, encourage them, offer support to keep them from falling, or maybe offer a simple reward like making them a favorite food. Im not sure if you can do that there but hey, its a start!
