I don't take that type of behavior personally.
Being a patient is stressful. Being sick brings challenges to people that we usually don't know about: financial, emotional, mental and physical. It can make you depressed, broke, and confused. I have always found patients can be calmed down one way or another, including having someone else. I've been the fill in when others got the boot. Recently, I saw a woman at home who had a wound vac. Within five minutes, she was threatening to call my supervisor. The vac went fine but she insisted someone "who knows what they are doing," check it. Some of us she likes, some she doesn't. I got her on call one night. I told her I would be happy to visit but I identified myself so she knew who I was. She chose to do a wet to dry and wait until morning for another nurse. It's really not about us. Sometimes, there are so many variables that we never really figure out what it is.
