I have been in hospice 5 plus years and the best advice I can give you will answer one of your questions. If you are lucky enough to have dedicated on-call nurses, do not keep your work cell phone
on after you are done for the day. In order to be able to be an effective hospice nurse you must "stop" working when your day is done. I refuse to keep my work cell on once I drive into my driveway. At that point it is family and me time. They only get about 4 hours a day and work gets about 10 hours. So once I am done, I am done! I feel if I am doing my job, my patients are well managed and the only time they would be calling is for new symptoms or emergencies. And that is the job description of the on-call nurse.
I do occasionally do some paperwork at home, but only if I have been unable to finish it at the office. It is not a routine thing.
The other questions should be answered with your orientation. You will learn the time to use the e-kit, how to deal with symptom management, families, and all the rest. Use the experienced hospice nurses you will be working with. It will take some time, maybe a year, to feel comfortable jumping in, changing meds, talking the family into using high doses of meds to manage symptoms. But it will come. Good luck, I hope you love it as much as I do!
