Nurse Training and Halacha

Hi, I am Chareidi and I want to study nursing.
I am interested in knowing the necessary halachik side to this profession. Do you know where I can start?
I am aware that there is a book that was published a while back for nurses, were you associated with this book and do you know if there is a newer edition in an english version or at least a newer edition.
The main, upfront questions that I have are;
Dressing, showering and assisting women in the restroom.
Placements on Shabbos and as time goes on, working on Shabbos.
Thank you and looking forward to your response
