Final answer:
The proper treatment for the Syndrome of Inappropriate ADH (SIADH) is to administer diuretics, which help increase water loss and address the effects of excess ADH.
Step-by-step explanation:
The Syndrome of Inappropriate ADH (SIADH) involves an overproduction or inappropriate release of Antidiuretic Hormone (ADH), also known as vasopressin, which leads to water retention and potential hyponatremia. Treatment for SIADH typically aims at reversing these effects by reducing water retention and correcting the sodium imbalance. In this context, the appropriate intervention would be Option 2: Administering diuretics. Diuretics would help increase water loss and mitigate the effects of an inappropriate ADH secretion. It is crucial to carefully monitor the patient for changes in blood sodium levels and overall hydration status while on diuretics. Options such as increasing fluid intake or reducing salt intake would generally not be suitable, as they could exacerbate water retention and hyponatremia.
