To be fair to this nurse, it wasn't clear what sort of nurse she was. Firstly, Was she a mental health nurse, learning disability, general nurse? Or was she a qualified nurse at all-many health care assistants and people in similar less qualified roles are called/call themselves nurses for ease of explanation. When did she qualify. Her training on diet may be decades out of date and with other issues taking priority over training sessions, this woman may not be as up to date with dietary knowledge as we expect. If her speciality was diabetes, well god help us all!
Secondly, the shift patterns in the NHS can be brutal, particularly at night. Breaks often don't happen, even toilet breaks can be few and far between. Often there is no capacity for members of staff to leave the clinical area even if they have an official break meaning that each bite of that healthy (or not) meal is punctuated by a member of staff saying” I know you are on your break but could you take this call/help me with this lady/talk to this relative” etc etc. I know this, I was that member of staff. I was not alone. Eating under these conditions becomes just cramming some calories into your mouth to keep yourself going before the work takes over again.
This poor woman did look older. Maybe she is on her feet day after day, twelve hours shifts, constantly changing shift patterns. Demands from all sides. Yes she should be taking care of her diet but lets give her a break. Nudging sixty and working as a nurse in the NHS-she deserves a medal
