The nursing home wants to send mom home, but we don't have 24 hour help. What should we do?

My elderly mother has end stage renal disease, COPD, congestive heart failure, diabetes, a pacemaker, defibrillator for AFib, degenerative disc disease, arthritis, and has broke both hips, a wrist, sternum, and now her pelvic bone. She has been in a nursing home for therapy 6 times in the last 3 years and had pneumonia 7 txs this year. They are wanting to send her home & we don 't have 24 hr help.
