A target weight procedure for disordered water balance in long-term care facilities.

1. Water intoxication is a severe complication of disordered water balance. Hyponatremia precedes water intoxication and can be identified through abnormal diurnal weight variation. 2. The St. Louis Target Weight Procedure (STWP) is a nonintrusive method that includes a client's baseline weight, frequent weights throughout the day, a target weight of 5% above the baseline weight, and restricted fluids if the target weight is exceeded. 3. The STWP was positively related to an increase in urine concentration; thus it is successful in restoring normal fluid balance.
