Much less autonomy in almost every country.
Depends on what area that you are working in, cardiovascular use quite a bit of the same equipment that we use in the US. Some countires use alot of assistive personnel, and others almost all RNs. Each place is unique but will be definitely different than what you are used to in the US.
Medications are usually on the British system as far as names, and may come in a different formulation or type that you are used to here. Simple example, in Thailand, Ativan comes only in tablet form, and not injectable, Versed comes only in oral form, etc. So it is not as simple as you think.
Remember that any foreign nurse wanting to come to the US to work must have US licensure. You will be required to do the same.
