Open Question: acres medical professionals allowed tons opt OF out performing unethical procedures?

I exercise a degree in the nursing for the sick and I plan, in trauma, to specialize and work in IT and in the ICU me. I was surprised to explain, if any, no view at present please practice, specialists to me could, if maintenance personnel are permitted to decide from the support with practice out which is not them also like abortion and other politically loaded expenditures. Thanks!
