I work in this field, in another part of the country. I probably would have done what your patient's carers did. We come up against similar problems every day with many of the people we work with. One chap springs to mind who has a less-than-sprightly swallowing reflex and trouble regulating his body temperature. He will happily put an entire sandwich in his mouth and then inhale bits of it if he's allowed to, so we have to take his lunch off him once he's got a decent mouthful, and give it back when he's swallowed it. If he gets too hot he will have a seizure requiring rectal administration of diazepam and then a trip to A&E, so when he gets a bit too warm his sweater needs to come off. Both of these procedures can p*iss him off royally some days, and he's a strong bloke. BTW we often get the 'Ooh, I couldn't do your job' response too, and we say 'learning disability' here.
