I worked overnight homecare for many years. I always sat in another room, lights and (sometimes) TV on and listened for my patient. (Vent dependent little ones usually). Ridiculous requirement from parents. Your agency needs to stand up for you. Mine did when parents 'insisted' that I work in my stocking feet to protect their carpeting. OSHA does not take kindly to people working without shoes!
As a 'side effect' of night shift homecare work - I can pretty much tell you everything you'd ever want to know about any product hawked in a middle-of-the-night infomercial!
I completed my BSN and part of my MSN online while working homecare. My patients usually slept, and it was the perfect opportunity as it forced me to study - there being not a lot else to do. (Obviously, the parents were OK with this as it helped my alertness - and they understood the challenge of remaining awake in a quiet house at 0300)
I'm applying for a job as an online adjunct instructor, and thought about picking up a PRN homecare job again and doing all of my grading around my patient's schedule.
