Just for the heck of it, here's what the finished concept map ended up looking like.
Like Nurse Practitioners Save Lives said, it's busywork, one more unneeded hassle in the run-up to the NCLEX.
Still, though, while working on it, I remembered a conversation I had here at the coffee shop with a medical student. She mentioned that her education and training didn't really leave her with any idea of what nurses do, what the scope of their practice is, and what their training entails.
I didn't pick a very good patient for this assignment, it was somewhat "simple", but even the care of simple patients can become as complex as you're willing to make it.
