Wisconsin Nursing Home Administrators (NHA) Practice Exam 2024 - Free Nursing Home Administrator Practice Questions and Study Guide.

A "locked unit" is typically a secure environment within a facility, such as a hospital or nursing home, where residents are not able to leave at their own will. This is often used for individuals who have cognitive impairments or behavioral issues and require a higher level of supervision. Option A, physical therapy rooms, and option C, visitor areas, do not necessarily require a secured environment. Option D, open space for outdoor activities, does not necessarily involve a locked unit. A locked unit would not allow residents to freely go outside without supervision. Therefore, option B is the most appropriate choice for a locked unit.
