I think the experience you'd gain from working nights is dependent upon your duties. If you are responsable for blood work, it is an excellent oppurtunity to become a blood draw expert.
Same thing with baths. If your hospital does them at night, you'd learn how to clean 'em up in fifteen minutes.
On down time, you'd have an excellent chance on learning rhythm strips. Hopefully , you'll have some good nurses on your shift. I enjoy taking Aides that I know are in nursing school
and teaching them procedures when I have a chance. Breaks up the day.
As for PM care, I guess you get used to it I tend to focus on what I'm doing rather than who I'm doing it to. If I'm alone, I do turn on the TV. Might be disrespectful, but the body noises scare the pants off me otherwise!
