I have to say that I think sometimes nurses have their act together more than doctors, especially the RNs. I actually had an experience with a nurse acting as a patient advocate recently.
My boyfriend was very sick so I took him to urgent care. When the doctor came in to treat him, the doctor barely listened to me when I was describing his symptoms and hardly noticed how sick my boyfriend was. He was going to give him a shot of something and just send him home without doing any tests.
Luckily, the RN walked into the room for something around the time the doctor was describing his care plan. The nurse took one look at my boyfriend and said, "Doctor, I think this man needs to go to the ER." The doctor took her suggestion and recommended the ER.
Honestly, even if the doctor didn't agree I was getting ready to take him there anyway. And it was a good thing, because my boyfriend had meningitis! He clearly needed further tests, not just a shot of something and to be sent home. I'm so glad that nurse was there to act as our advocate.
