How to return the last row using ROW_COUNT

How can I have the following statement below return the last or highest row for rn?

SELECT wo_number, first_name, last_name
    FROM (SELECT wo_number,
                 first_name,
                 last_name,
                 ROW_NUMBER() OVER(PARTITION BY wo_number ORDER BY first_name, last_name) rn,
                 COUNT(*) OVER (PARTITION BY wo_number) cnt
            FROM ba_view_wo_labor
           WHERE skill NOT LIKE '%INSPECTOR')
   WHERE cnt > 1 AND rn = 1
ORDER BY wo_number
