Always document the things you do and what you dont, as long as you're doing your job as a Nurse, you dont have to worry. The problem is, when the Doctor order things that may harm the patient. In cases like these, always ask or refer it to your superior/head.
What can I say, Its the nurse's discretion...or should I say common sense? Its a matter of conscience... we could give the infection or vice versa right? What I learned from nursing school is everytime wecould make contact on body fluids and the like, we should wear gloves...we should should also know if our patient is immunocompromise then we should do what is right. remember we are NURSES:nono:
