One big yet simple piece of advice: KEEP UP ON YOUR CHARTING during LABOR , cause when pushing, you have no time. Keep your labor charts up to date as you go. This will save you time later. Chart everything on the ob fetal strip, so if you need to, you can transcribe what happened when onto your charts after delivery. Keep your coworkers and the OB tech up on what's going w/the patient. If you are close to delivery, let everyone know, so if help is needed, they will be aware. When it's time to push, let the other nurses/charge nurse know, also, so they know where you are and will keep an eye on the strip in case they are needed. Keep the doctor abreast of changes and when pushing will begin, as well.
Please: Keep the room clean, free of clutter and keep your tubes and lines free of tangles and organized. This will help in the case you have to go for an emergent or fast c/section; you will regret having a mess to untangle and slog through at that time. Keep everything in order and uncluttered. And PLEASE empty the trash if it overflows. NOTHING is more unpleasant for everyone than stinky trash, particularly red-bag stuff and stinky overflowing laundry bags. Keep the room clean for your sake as well as your patient's ---you wont' regret it.
Anticipate what the OB or MDA (anesthesia) need ahead of time, if possible. For example, if a patient wants an epidural from the get-go, please, assemble the things the MDA will need to get the job done, as much as possible, ahead of time. Things like the epidural pump and drip, as well as the kit and gloves, right size for the MDA on call, will help get the job done MUCH quicker. Also if you know a given OB is going to rupture membranes in a labor patient, have plenty of towels, sterile gloves, lubricant, the amni-hook and other things ready ahead of time. That way, you won't be caught unaware and un-ready for this. If a given OB uses IUPC a lot, have that ready to go, too.
Good luck. You will learn with time what works for you. I am one of the most anal nurses on my unit, you could ask anyone. I like organization, in charting and my patient rooms. It's saved my butt time and again.
