The program I am enrolled in made the PDA part of our tuition. iPAQ Pocket PC. We were also required to download the folowing from Skyscape.com and I highly recommend them. NOTE: Unless you're in a big hurry, request the CDs instead of downloading - never know when you can't get to the internet and you need to reload. Tabers Dictionary, Davis's Drug Guide, Nursing Procedures, Practical Guide to Health Assess., Disease and Disorders, Nurse's Manual of Lab and Diagnosis Tests-4/e - all very good so far and about $200 total. Also highly recommend downloading for free Archimedes Math Calculator. Just downloaded Nursing Diagnosis Handbook by Ackley and Ladwig for $42. This is already helping big time with my Nursing Care Maps. NANDA approved. All of these books fit on the removable card to keep the pocketPC freed up.
