For facilities licensed after January 1, 1964, the minimum usable floor area required for each bed is _____ square feet.

The correct answer reflects the standards set forth for licensed health facilities regarding minimum usable floor area per bed. Specifically, for facilities licensed after January 1, 1964, the requirement is established to ensure that each resident has adequate space, which is critical for their comfort, safety, and the overall operational efficiency of the facility.

The requirement of 70 square feet is designed to allow enough room for essential furnishings, mobility, and access to medical care, as well as promoting a better living environment. Understanding this regulation is crucial for health facility administrators, who must adhere to these standards while planning layouts and ensuring compliance with licensing requirements.

In contrast, the other options—60, 65, and 75 square feet—do not meet the specific regulatory criterion, as these figures fall outside the established parameters for facilities licensed after the stated date. The standard reflects a careful consideration of the needs of residents and the operational realities of health care environments, thus emphasizing the importance of familiarity with these regulations in the realm of health facility administration.
