stethoscope for severe hearing loss

I am very concerned. I have always had hearing loss but in the past year it has gotten very bad. I have severe loss in my right ear and moderate in my left. I am now wearing bilateral hearing aids. (I have always had to wear a hearing aid in my right ear). It is getting harder and harder to hear blood pressure. I keep having to have another nurse check me. It is getting embarrassing. I am an LPN by the way. I have an older electronic adscope which isn't always doing the trick right now. I am also about to starting nursing school for my RN. I am done with my pre-req's. I am very concerned about hearing lung sounds. I am crying and losing sleep over it. It seems silly but I would hate to come this far and not get my RN because of my hearing loss. Does anybody have severe hearing loss or know anybody who does who could give me advice? Is there a stethoscope I could use that would be better? It is breaking my heart. I am going to see an ENT but apparently my hearing loss is do to calcium deposits and there is nothing that can be done. I have searched older posts but most people have mild hearing loss or the thread is very old and the links are out of service. Thank you so much. Colleen
