I need answers from a labor and delivery nurse please for a school report.

If a labor and delivery nurse could answer these questions, I would really appreciate it. I have a report for my transcription class about OB/GYN. 1. What type of additional training do physicians need to go into OB/Gyn?
2. What other health care professionals do you come in contact with and why? 3. What conditions, diseases, or injuries do patients seen in the OB/GYN have other than pregnancy? 4. Your name, and place of employment. Thank you for any help you can give me.
Try posting this in the OB section....good luck
