If you are not getting any answers then make a fuss!! Seriously do it! You can ask to speak to the nursing unit manager, and if she doesn't come to speak to you, then ask to speak to the patient advocate. You have every right to know what is happening and there is no way that they should be fobbing your worries off at all! I don't care how busy they are, there is always time for every patient.....don't let them get away with it! Kick up a stink!
