CNS and bioethics

Not as Clinical Nurse Specialist but you can get a Master's degree in Bioethics.

Depends on whether you're asking about getting a degree in bioethics, or a job that focuses on bioethics, I guess.

Several years ago, I worked as a psych consultation liaison nurse at a large teaching hospital (credentialed as a child psych CS), and we did a lot of work with the hospital ethics team and hospital counsel. It would probably have been possible to move more in that specific direction with my job, or to find a job elsewhere that focused more specifically on bioethics, if I had wanted to do that.
