Are you asking for the purposes of your state test, or for real life purposes? Because in real life, very rarely do I have the time to do things like soak anyone's feet, and they just get scrubbed and their nails clipped with their baths. For the sake of the test, I'd double check to see if your book lists a specific time, otherwise just a few minutes.
As for deodorant, ask the alert and oriented people. People who AREN'T alert and oriented, I don't ask, I just say something like "I"m going to put your deodorant on now", or I'll ask them to help raise their arms if able.
