I wholeheartedly agree. She should not be a nurse for starters, nor should she be serving in the military.
I am disinclined to be cared for by a hotheaded nurse, and I sure as heck don’t wish to have some raging lunatic wearing the uniform either.
Nurses deal with people in pain and in crisis. It's important that the nurse be able to maintain calm in the face of others who may be hurting, angry, or irrational. This nurse does not appear to have the required mental state to be a nurse.
