I just got off work. I work as a Nurse in the ER.
Nurses practice many specialties within the field.  Do you have a specific one?
I work a registered nurse. Currently I work at a military hospital here in San Antonio. Mostly in the ICU.
Nurses have to develop a plan of a care to help work with the doctors, the patient, and the patients family.
Absolutely. A big part of my day is just talking to the patient's families. It's amazing how many people go to the ER everyday.
In the US and the UK advanced nurses can prescribe medications and other therapies, although the details are regulated on state level.
I have to go through the doctor for most prescriptions although I heard in a long time ago we were able to prescribe Ultram or Tramadol to patients as needed.
Nurse practitioners are even permitted to practice independently in a variety of settings.
