If you have lights on stands, you may want to bring an assistant who can carry the lights for you and make sure everything stays safe.
If the nursing home has a drop ceiling, and you want to avoid the danger of light stands, consider a drop ceiling scissor clamp to hang a small light from the ceiling.
Natural light is best, of course. Soft light from windows is very easy on your subjects and more flattering than most artificial light.
And/or, consider a small camera light just for filling in the shadows. That would avoid the problem of light stands and cables, it’s inexpensive, and if handled appropriately (with diffusion), can be beautiful. It would be even better to hand that small camera light to an assistant, who stands a couple feet to the side, so that your subject can look at the camera without squinting.
