C.Ann, with regard to the fluid retention problem, I would talk to his doctor and see if a Physical Therapist can see your DH, even for what is called "passive" range of motion. I don't knoeww how much he is moving, but my guess is that if he is in ICU, he's not moving too much. Fluid tends to pool at that point, and even increasing the limb movement a little bit will help. The Physical Therapist may also be able to give you guidance as to where something like an extra wide slipper can be purchased. I know there are catalogs etc that have specialty items like that, and often the therapists have access to that info.If the doctor decides against the Physical Therapy for the moment, and he/she may, depending on what your DH's condition is, then take a walk to the PT Dept and ask them about the slipper info.
As far as the nurse, I would definitiely go to the supervisor of the unit and speak with her about not having that person assigned to your DH anymore. I know on my floor, my supervisor welcomes complaints(as well as compliments!)from family, and would prefer to hear about while the patient is still there and the situation can be rectified. Rest assured, your husband's care won't suffer if you complain, and if you feel it is, every supervisor has a supervisor, and so on, and you keep going until you get satisfaction. You may also be doing the supervisor a favor, because she may have had several complaints about this particular employee, and yours may be the straw that breaks the camel's back, as far as enabling her to do something about it. If there's one frustration my own supervisor has, it's that she needs multiple complaints against a problem employee(enough evidence/documentation for the lawsuit!)before she can take action.
Hopefully, I've been helpful C.Ann. My continued prayers for you, your DH, and your family. God Bless!
