Thanks for this post! The care plan constructor mentioned is great! Also, here's a link to another care plan constructor I discovered:
http://evolve.elsevier.com/Ackley/NDH/
It's based on the highly regarded Nursing Diagnosis Handbook by Ackley & Ladwig. You'll be asked to register (no biggie) and as a result you'll get your own page. It may take a little poking around on your page to find the link to the constructor, but it's worth it. It's similar to the Gulanick careplan book constructor mentioned in the original post, but it seems like there are more diagnoses listed. I had trouble getting it to work when I first tried it, but the next day it worked fine. They also have support which promises to return emails the next day.
Both constructors offer printable care plans from which you can easily copy and paste into a text or word processor file for editing and formatting.
Happy care planning!
