It is understandable why a charge nurse would make the decision to room a waiting patient—the capacity is there and available. The challenge is having staff available to take care of that patient.
Instead, in these circumstances we propose that departments prioritize the flow of the patients already being treated, so that fewer spaces (and staff) are required.
If a project is already complete, we can work with the staff to determine the best use of the space they have been given. If the department is under construction, perhaps there is some minimal redesign that can be considered without (too much) impact to the budget, and with no impact to the schedule.
Regardless of the physical planning that has already occurred, you still need to protect your investment and plan for how you will manage patient care, determine appropriate staffing coverage, and adapt as patient needs change.
