I am having issues with one of my coworker RN. I like her, but she reacts to certain things in a strange way sometimes. Recently, she became upset with me, accused me of "micromanaging" her, and requested that the manager meets with both of us. Here are some of the situations. 1) We work in a psych unit. A young patient punched an older patient in the face. The older patient, who was my patient, fell backwards and hit his head on a concrete floor. We assisted him, and I ran to another end of the unit to get the doctor's phone number. As I was walking, I saw this RN walking towards the patient. I politely asked her "M..., can you please get a set of vitals? I am calling the doctor". She had a weird reaction to my words. She said with arrogance in her voice "In this situation, I am going to follow the charge nurse's instructions". I was shocked, but went on and asked another person get the vitals while I was obtaining the MD phone number. Afterwards, I said to that RN "When a patient falls and hits their head, you don't need directions from the charge to get vitals. It is basic fall protocol". She looked frustrated but didn't know what to say. I really don't understand what her problem is! That was totally not the behavior of a nurse. 2) One day, we started the day being short staffed. Every RN took more patients than the normal ratio. Midday, one RN felt sick and needed to go home. Her patient load got divided between us. So, we were super short. The charge nurse said they didn't find anyone to replace her. In about 15 minutes, I see that nurse strolling in. Apparently, she agreed to come in extra. I thought she was going to replace the sick nurse, but no. Instead, they had her take a new admit. I was unpleasantly surprised, but didn't say anything. She came for 4 hours, and the admit takes about 1.5 hours. So, she had plenty of time left. I was running non-stop all day. As I walked in the clean utility, I see that nurse pouring shampoo into measuring cups and then emptying the trash can. I was super surprised as these are thins that an RN would do only if she had plenty of free time. I could use help with a couple of little things and, I am sure, other nurses were too. I asked her "M..., do you have free time?” She appeared startled and said "I need to check with the charge nurse". I asked her "Did the charge nurse not tell you to check with the team if anyone needed help?” She said arrogantly "I expect that by now you know how to do your job". It felt like a slap in the face. Yes, I know how to do my job. I also know that if I came to work extra, was making double pay, and had no patient load, I would sure as heck check with my teammates if anyone needed help. I replied to her "I thought your duties were of an RN, not of a housekeeper". I know I reacted emotionally. She got mad at me, said that I was rude to her, said "I will not allow to be micromanaged", and wrote an email to the manager. She also sent an email to me asking me not to approach her unless it is about patient care of unit safety. I replied that it was totally find and that I never approached her with any unprofessional or personal requests. A little background. I am an RN with 17 years of work in various hospital settings. She is older than me, became an RN about 5 years ago, and worked in a nursing home. That might help to explain her not knowing the fall protocol. However, her responses to me are just weird and unprofessional. She used the word "micromanaged" a few times. Never, not in any circumstances I directed to her to do anything. It was always a polite request or inquiry. This is a part of normal daily teamwork. I just don't know how to work with her. Now, she wants to meet with a manager. What is there to say? Maybe it sounded rude that I said about housekeeper. I can apologize for that. In all other situations, I believe I was acting appropriately and in the best interest of the patients. Does anyone have any insight or advice?
