Nursing care priorities for the child with symptoms of SIADH include:

• A. encouraging fluid intake
• B. monitoring for urine ketones
• C. obtaining daily weights
• D. restricting sodium intake

Answer: (C)

In SIADH, the body retains water due to excess ADH, causing fluid overload and dilutional hyponatremia. Daily weights are the best way to track fluid balance because small changes reflect shifts in total body water; a gain signals worsening fluid overload and guides adjustments to fluid restriction and overall management. Encouraging more fluid would worsen the hyponatremia, and monitoring urine ketones isn’t relevant to SIADH. Restricting sodium intake isn’t the primary approach and can worsen sodium balance; the focus is on monitoring and managing fluid status, with daily weights helping to detect changes early.
