As an EMT, I can't help open a bottle of their meds or anything unless specifically stated in my protocol.
Sure you can as a bystander given you know the patient, you weren't called to them, you aren't treating them.. and you have nothing to do with being a Mr at the time. But then... why would you be assisting them?
If you are opening a medication bottle for them and they are in need of help, that medicine just might not be a good idea at that given time. Don't do it. It isn't worth it and how often does someone have hemostatic dressings laying around? If you go to someone with it, you are intending to treat them. It isn't worth it. If they are bleeding that bad, call an ambulance
And I don't think you can assist in opening med bottles as an EMR. Treatments can change based on what the patient takes. I don't assist in opening med bottles as an EMT for patients I'm treating.
I spike iv bags, I hand my paramedic her bag and open it, but I don't open bottles for patients unless it is: their own nitro, oral glucose, activated charcoal, aspirin or a bottle of water and I even ask my medic or call MD for water if we are a ways out and they are insisting. We are paramedic conditional, sometimes a paramedic is there, sometimes not. If a ride will be a while and patient is thirsty, I won't hesitate to call for water and 9 times out of ten I would be told no. Except in cases if transfers with surgery in the morning.
