That's a whole hornets nest waiting to be kicked into life. Personally I don't think it matters what religion/color/dress style a patient adopts - when they're in our hands, they are just The Patient. They all bleed the same color. They all have the same body systems. Taking the time to explain as best you can why you need to do something and respecting the patient as a human being, you'll never go wrong. Besides, just drive a bit quicker and make it 'someone else's problem' at the ED.
