Which condition should the nurse be aware of that is associated with the syndrome of inappropriate secretion of ADH (SIADH)?

The correct choice is fluid retention, which is a key characteristic of the syndrome of inappropriate secretion of ADH (SIADH). In SIADH, the body produces excessive amounts of antidiuretic hormone (ADH), which leads to an abnormal retention of water in the body. This results in dilutional hyponatremia, where sodium levels in the blood become low due to the excess fluid. The retained fluid causes an increase in total body water, which can manifest as edema and can affect various organ systems.

Fluid retention in SIADH can lead to symptoms such as weight gain, decreased urine output, and potential swelling due to increased intravascular and interstitial fluid. Recognizing fluid retention is critical for nurses because it can help in monitoring the patient's status and guiding treatment interventions, such as fluid restriction and potential medication adjustments.

While hypertension may be a complicating factor in some scenarios, it does not directly describe a core effect of SIADH. Hypernatremia, on the other hand, would indicate a lack of water retention and is not associated with SIADH. Diabetes Mellitus is a separate endocrine disorder and is not directly linked to the mechanisms underlying SIADH. Understanding these distinctions is crucial for proper nursing
