A Nursing Student's Questions on Caring for Muslim Patients

As-salamu alaykum, everyone. I'm a guy who's studying to become a nurse. Most folks where I'm from are Christian, and I'm not particularly religious myself. But once I get my license, I really hope to work in a more diverse community. I'm a bit worried that when I get the chance to care for a Muslim patient, I might accidentally do something disrespectful without even knowing it. I don't know a whole lot about Islam yet, but I'm trying to read up on it. I've got some questions about how to treat Muslim patients properly and make sure their dignity is always respected. I'm especially concerned about caring for women, but I'd like to know about things specific to men, too. And if there's anything I haven't thought to ask, please tell me-I really want to learn. During an assessment, I often need to touch bare skin, like placing a stethoscope on the chest to listen to the heart and lungs. If I'm treating a Muslim sister who wears hijab, is there a specific way I should lift it? When I looked at pictures, I didn't see any buttons or zippers on it. I also sometimes need to check the head. If my patient can't remove her headscarf herself, would it be okay for me to ask if I can help take it off for her? I'm aiming to work in an Emergency Room. In emergencies, we might need to cut away a hijab using trauma shears. What kind of headscarf could I buy that would be suitable for as many Muslims as possible? I've heard stories about nurses and EMTs making temporary coverings, which is kind, but I'm sure it's still really hard for the patient. If a patient is bedridden and can't perform their daily prayers, is there anything I can do to help make that easier? I can imagine how tough it must be to have a lifelong routine of prayer and suddenly not be able to do the physical movements. We have chaplains at the hospital who are supposed to support all faiths, but they're almost always Christians. Have you or your faith ever been accidentally disrespected in a healthcare setting? If so, what happened, and what would you have preferred to be done differently? Jazakum Allahu khayran for reading through all my questions.
