I am wondering if we should buy the NANDA-I book or just go with our care plan books? I'm having a hard time. I know what to do.. But when it comes to where to look in the care plan book I'm lost! I'm having a really hard time. I've clustered my data, etc. Also where do we find the R/T factors? I know that sounds silly. But some of the diagnosis in the care plan book have R/Ts but others don't. And i know we are suppose to go on the defining characteristics-- i guess i just don't know where to look. Any help or explanation would be greatly appreciated!
