Ah, but we all must remember that as a nurse, we must also explore why it is that our personal boundries would have a thing to do with what someone else chooses to do regarding their own body and own health.
Just because one personally believes something to be wrong, doesn't mean everyone does. Just because personally one would not have an abortion, take birth control, smoke and have COPD, eat incorrectly and have high blood pressure or diabetes doesn't mean that the patient's one encounters will not.
A huge part of nursing is to be non-judgemental in the care you provide. There are waivers that one can sign that state that nurses prefer not to take part in what they believe to be morally incorrect. However, as a general rule, we are there to care for patients, not take some sort of moral/ethical stance.
