(f) OCFS shall provide each clinical health services authority with licensed health care professionals sufficient to meet the health care needs of the resident population. In determining the adequacy of each health care staff, OCFS shall take into account factors including, but not limited to:

1. (1) the annual average size of the resident population under the care of the clinical health services authority;
2. (2) the level(s) of care to be delivered by the clinical health services authority, as defined by OCFS and consistent with the requirements of this Part; and
3. (3) impediments to or limitations upon resident access to health services associated with security imperatives and/or physical plant location or configuration.

(g) At a minimum, the following health care staffing requirements shall be met:

1. (1) each clinical heath services authority shall be staffed with one registered professional nurse on a 16-hour basis each day and shall provide for the continuous access, without undue delay, to such nurse by all residents for whom the clinical health services authority is responsible. Reasonably proximate clinical health services authorities may share nursing staff for purposes of compliance with this subdivision;
2. (2) if a secure facility operates an infirmary unit, and it is occupied by a resident, it shall be staffed on a 24-hour basis each day with a registered professional nurse, a licensed practical nurse and/or a nurses’ aid in sufficient number to furnish each infirmary patient direct nursing care and related services including assessments, treatments, medications, diets, and other health services in accordance with each resident’s treatment plan prepared pursuant to a physician’s order; and
3. (3) the services of a physician shall be available on call to each secure facility every day during the hours in which no physician is present within the facility.
