Final answer:
The nurse should identify mental confusion as an indication that the child is developing syndrome of inappropriate antidiuretic hormone secretion (SIADH).
Step-by-step explanation:
True
The nurse should identify mental confusion as an indication that the child is developing syndrome of inappropriate antidiuretic hormone secretion (SIADH). SIADH is a condition where the body releases too much antidiuretic hormone (ADH), causing the kidneys to retain more water than necessary. This leads to a decreased sodium level in the blood, which can manifest as mental confusion among other symptoms. Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a condition where the body retains water excessively, leading to dilutional hyponatremia (low sodium levels in the blood). Therefore, the nurse should identify mental confusion as a potential sign of SIADH due to the effects of hyponatremia on the brain.
