The one thing that I learned is never hesitate to ask for help. I was very nervous my first clinical, I took a look at my first patient and said, "this lady is way to fragile, I dont want to hurt her" but by the end of the day I really found out how amazing she was. I found that on my first day they tend to understand more that you are learning and try to give you someting simple like vitals to start with, and that helped me start the introduction process with my patient, and it made me less nervous. It is pretty rare, but my clinical instructor made my whole group give injections on our first day, which was very nerve racking, but now that I have done it I am not so afraid of it. Best of luck with your first patient I am sure that it will be great, just have a smile it makes everything go so smoothly!!!
