I have waited well over 40 minutes for things in a hospital before...and yes, I was pushing the call button every 5 min and sending my husband down to the nurses station. Most of us do understand that we are not the nurse's only patient...and by no means did I interpret that Murgie suggested her son was *the most important or in *the most pain. She simply stated/implied that she felt the nurse had an attitude towards her/her son and was coming across in a rude fashion (thus, coming here for comfort and support). A nurse is a professional and we are paying them for their services. By no means do you have to keep a nurse that you are uncomfortable with. Hospitals have patient advocates that are typically wonderful at helping resolve a situation, or you can ask the nurse/floor supervisor for another nurse with more experience in handling both pulmonary AND Diabetes.
I am sure the nurse had a reason for being rude (possibly even unknowingly provoked), but she is the professional and is in the wrong for having any type of poor attitude towards a patient. If the nurse is upset, frusterated, or simply having a bad day...it needs to be checked at the door period. Anyone in any type of customer service can tell you this.
I personally would have confronted the nurse myself (kill em' with kindness attitude) and had some sort of sarcastic response to let her know that what was said is unacceptable. I then would sh*t my bed and make her day fifty million times worse that it already was (Juuuuuuust kidding)!
Murgie, I sure hope your son is feeling better and your experience at that hospital improved during his stay. Get some rest for you, too. Your son needs you at YOUR best!!
