One month is doable.
Realism is a toss up. I will start with the obvious questions ---
- How much do you know about MDS?
- How many hours a day will the consultant train you, days/wk?
- After a day's training, how much time are you alloted to read the RAI Manual, go through a free online training?
- Since you don't have a current MDS coordinator, will you and the consultant also be doing the active MDS assm'ts in the interim?
... and the lists can build up when your Allnurses MDS peers chime in.
In the meantime, take an RAI Manual home. Browse through Chapters 2, 3, and 6. If you'll be involved in care planning, include Chapter 4 and Appendix C. If you'll be responsible in submitting the MDS assm'ts, might as well look through Chapter 5.
There are many helful insights here
Albeit, even after years of experience, a seasoned MDS nurse will continue to learn. Good luck!
