I think traditionally we (ER Nurses) tend to be very uncomfortable with a women in labor and your experience would be a welcome one. Plus I just stink at getting FHT's in any mother less than 20 wks...
I agree with the above post get your PALS (you probably have it?) and your ACLS, the TNCC can probably wait and actually helps you learn if you have at least been exposed to trauma.
Good luck and HAVE FUN!
