It is contemplated that items of assistance to be provided to indigent veterans or their family units will not, during any one consecutive period of time, exceed ninety (90) days. If it appears that items of assistance should be provided continuously beyond this 90-day period, they will be provided by placement in the Iowa Veterans Home, if available, unless it is determined by the Commission that it is better for the family unit of the indigent veteran to continue to receive items of assistance on a month-to-month basis.
