I work at a 43 bed free standing psych facility. 23 of those beds are C&A. Days and evenings we're staffed at 4 nurses and 7 MHAs (psych techs or what have you). Two of those nurses are dedicated to C&A, a med nurse and a unit nurse. The other 2 are adult. The children's unit gets 2 staff adolescent gets 2 and then there's a float that goes between all units. Our staffing doesn't start to drop until we reach 35 pts in the whole hospital, then we go to 3 nurses and 6 staff and from there it drops accordingly. On weekends it's always 3 nurses and 6 staff on days and evenings. 2 nurses on nights regardless of the census or day of the week.
