"Placed out of reach" is a vague statement that could mean any number of things, and would be very easy to do by accident. You have a 50-50 chance of setting an unfamiliar hemiplegic's lunch tray on the dead side table if they're uncommunicative and the chart is missing or incorrect, or you simply don't have time to check it because you're caring for five times as many people as you're supposed to be. Flip a coin, tails means you just placed someone's food out of reach due to a poorly-timed nap. Congratulations, you're now Nurse Hitler because of a slippery statement that implies you're deliberately torturing them.
Requests for water are piteous and heart-rending, but (assuming you can even hear them from the other end of the corridor in a noisy place) what can you do when you're already catching an assisted walking resident who slipped in a puddle of urine, trying to clean another who lost bladder control before the urea damages their skin and sets them up for ulcers (you have about 4 minutes), looking for the med-aide to find out what the hell someone with an allergic reaction was actually given, dealing with the grieving relatives of someone who just passed, late to move someone bedridden who has to be turned to prevent pressure ulcers, and answering calls for food from four different directions? And that's mostly stuff an assistant can do, a full-fledged nurse gets it even worse.
Nursing isn't easy. Understaffed nursing to a standard people deserve is essentially impossible.
But you needn't take my word for it. Get CNA training and do your clinical training in a real care facility, and see what it's like. Bring a helmet and some powerful stimulants.
