New grad position
Congratulations on completing nursing school- alot of opportunities await you in your future. You asked pros/cons of a peds and OR position. My first question is what is your ultimate goal? If you really love the OR and cannot imagine doing anything else, by all means take the OR position. If you like floor nursing and want to be able to 'move around' , peds may be your best bet ( actually med surg may be the best choice for the first year- especially if you want ED or critical care in the future). Peds is pretty intense, and jobs are more difficult to find than med surg jobs if you are thinking about relocating in the future. If you love kids and their parents, and like a challenge, Peds will fit the bill. Both Peds and OR may be self limiting, depending on the actually units, but if you are not in a Children's Hospital, most peds units take med surg overflow due the the variable census.
There is alot to think about, but your question should be which position will give you the experience you need to reach your ultimate goal. I have found that if a new grad is happy and comfortable in the unit, the 'pros and cons' really mean very little. Your first year is primarily adjusting to being an independant professional nurse. You will need to become part of the unit as well as using and improving your critial thinking skills to incorporate the art and science of nursing. Whatever you do, always remember to provide the best patient care you are able to give. Welcome to the profession!
