I've always wanted to be a children's nurse and I have decided to apply. However, one thing that I'm a little worried about is that I can be squeamish at times, and when I see someone hurt I get a tingly feeling in the same area of my body and pins and needles rush down me. It's more of an issue with family members than strangers, and I've been able to improve on this since doing a first aid course and kind of learning to detach from how the person must feel and focus more on what I should to do - if that makes sense. To me, being squeamish seems like a natural response to seeing someone hurt, and that it can be something that you become desensitised to as a medical professional?
I also wonder how do medical professionals avoid getting ill all the time? If you're dealing with children with vomiting and diarrhoea, or the flu or other infectious diseases? Obviously you would use strict hygiene measures and infection control but is it common for medical professionals to get ill a lot, or does their immune system adapt?
