Its hard to keep things quiet at night.. Just like during the day, you have vents, doors, pumps, carts, codes, emergencies, needed supplies etc.. The noise, work, assessments, meds, baths, dressing changes etc does not stop because it is now night. A loud mouth, tell them to tone it down but a whispering night shift will never happen.. We are trying to do our work and yes talking is part of it.. Sleep will happen when you get home and no longer have q1h neuro checks, assessments and meds all hours of the night.
For AAO pts, we do close the door so it is a little bit better for them. We also turn down the lights at night to help.. At my last facility we gave a goody bag with soft ear plugs and a sleeping mask
