You're running mysql_real_escape_string on the variables AFTER inserting them into the string!

You'd want to do

   $hnum = mysql_real_escape_string($_POST[hnum]),
   $rnum = mysql_real_escape_string($_POST[rnum]);
   $adate = mysql_real_escape_string($_POST[adate]);
   $sqlque="INSERT INTO t2 (HOSPNUM, ROOMNUM, ADATE, ADTIME, LASTNAME, FIRSTNAME, MIDNAME, CSTAT, AGE, BDAY, ADDRESS, TELNUM, SEX, STAT, STAT2, STAT3, STAT4, STAT5, STAT6, STAT7, STAT8, NURSE)
  VALUES ($hnum,$rnum,$adate', //etc. 

Even better, don't create SQL queries out of string substitution at all. I suggest using PDO and prepared statements/parameterized queries. A prepared statement takes care of escaping the input for you. Here's a good link with a rundown of how to use PDO instead of the mysql_* commands.
