Essential tool used by nurses and nursing students for 25 years. This 6 page laminated quick reference guide covers the need to know whether you are studying, prepping for tests or already a working nurse. Just the facts and answers arranged and organized to have as much info possible at your fingertips in color coded sections to find what you need and to promote memorization. We have heard first-hand how our nursing guides have boosted grades, helped with passing tests like TEAs and NCLEX, reduced some stress of academic intake and how this guide has even been stolen by other nurses from the nursing station (true story). Authored and updated by two accomplished nurses, teachers and writers Jill E. Winland-Brown, EdD, MSM, ARNP and Julie Henry, RN, MPA, you will not find a more inexpensive reference that offers so much support.
