Hi and congratulations. I hope things work out well. I like "Inpatient Obstetrics" by Saunders (can be found at
www.awhonn.org or
www.barnesandnoble.com)
its outline form is easy to pick read, put down and pick up again. And it does well at "covering the bases" in OB nursing.
GOOD LUCK in your new position. Make darn sure you get fetal heart monitoring and NRP classes/certifications ASAP!
