There aren't any other local hospitals. The nearest other hospitals are in Seattle. Her hospital is in Silverdale. Silverdale and Seattle are separated by Puget Sound, so even though they are only maybe 15 miles apart, you either have to drive the long way around Puget Sound or you have to take a ferry.
Without crossing Puget Sound the nearest other hospitals would be in Tacoma which is around a 40 mile drive away.
Hospitals were understaffed prior to Covid (because managers were being cheap and refusing to have sufficient staff) and with many anti-vaxxers assaulting and threatening healthcare workers, many nurses quit the industry.
