I am a nurse clinician, and have been a nurse for 26 years. I have worked at my current place of employment for over 17 years and currently hold the position of head nurse. It is in a community setting with a pediatric clientele. Recently we had a medical emergency (code blue), the client in question was having a seizure and had turned blue. There was no doctor on site, so it became my job to "run the code". (I.e direct the other nurses how best to help this patient) Near the end of the code, one of the LPN's (formerly called, nursing assistants, but they are now called licensed practical nurses), starts contradicting one of my directives, and our manager (an occupational therapist), agrees with her and implements her directive. Let's call the LPN Sandy and the Manager, Eva (not their real names) The clients seizure had ended, but his oxygen levels were low and his heart rate was fast. I needed to monitor him while we waited for an ambulance. I had asked a bystander to please move out the way, as she was blocking my view of the patients face (the bystander was consoling the client). Sandy the LPN disagreed with me and stated that the bystander should retake her position, and my manager Eva agreed and told the bystander to resume her position which consequently prevented me from seeing the patients face (an important source of clinical information). In addition, it prevented the patient from entering the "postictal state" which is a kind of a sleeping phase that happens at the end of a seizure (the bystander was stimulating him, singing to him, etc). In addition it added an extra voice to the cacophony of voices that were asking questions, commenting, etc. I am hearing impaired and wear hearing aids, so the more voices there is the more difficult it is to hear. The ambulance came and took the child to the hospital. Afterwards, I met with the team of LPN's who had intervened with the child, because one of them was shaken and needed reassurance. After I reassured her, Sandy says (in front of the nursing team) "I really did not like when you asked the bystander to leave" I responded that this was best practice and also institutional policy. She continued however to argue back and forth with me about my decision (which she ultimately overridden). She then proceeded to tell me she did not like that I was telling people what to do, she began imitating me "get me the stethoscope! get me the defibrillator!" She felt I was too bossy and she did not like my tone of voice. I was hurt and embarrassed. I told my manager how I felt. My manager states she did nothing wrong because "everyone is allowed to have an opinion".
