That may be a bit different then by region, as most Pastors here just check in with the front desk and not necessarily with the actual nurses station on the floor. As for the psych wards, I've got no clue on that one as I've not had any experience with them at all. I've heard that they do visit, but I don't know for certain.
all visitors are required to check in with the nurses’ stations due to health restrictions, ie infection control, mealtime and medication routines, permitted and not permitted items ie flowers, plants, and patient/family restrictions on who is allowed to visit.
Front desk calls the nurses’ station, in my experience.
