I can't answer your question, but I think being an actress is a valuable skill for nursing. Nursing (any health care profession) is performance. Voice and presence are therapeutic, and knowing how to manipulate those for maximum effect is what the best learn on the job. You interact with the public constantly, both patients and coworkers, and have to communicate both verbally and nonverbally in a wide variety of situations, some highly emotional and traumatic, some highly rational, with every kind of personality, educational level, and social class out there. I've thought acting experience would have helped me negotiate the performance and communication part more smoothly
and less awkwardly. There are days you don't want to be at work, you're grumpy, the pts or family are upset, or you have a personality clash with somebody, and acting skills would be very helpful.
I worked once with a nurse who I later learned did some voiceover work in the past. She had a lovely voice which must have been therapeutic for her patients. I think nurses who sing well also have great voices and know how to use them well therapeutically.
If you go into nursing, maybe you could teach performance and voice workshops aimed at nurses and health care professionals! Performance should be more explicitly addressed in nursing and APN programs. In regards to my field, I see birth as performance or ritual and the midwife or OB who is the healer or shaman or leader who directs the energy and action in the birth room.
Best of luck and I hope there are actress/nurses here who can answer your question.
