A nurse is caring for a client weighing 160 lbs. who sustained burn injuries to both legs completely. There's a pending order for 0.9% sodium chloride. How much fluid is the client to receive for the first 24 hours? (Round to the nearest whole number.)
The Correct Answer is ["10","472"]
Both legs account for approximately 36% of total body surface area (18% per leg × 2).
Convert weight to kilograms: 160 lbs ÷ 2.2 = 72.73 kg
Using the Parkland formula:
4 mL × 72.73 kg × 36 = 10,472 mL of fluid for the first 24 hours

Explanation
A. Weight loss is not typical in SIADH; instead, fluid retention often leads to weight gain.
B. SIADH causes excessive release of antidiuretic hormone, leading to water retention and dilutional hyponatremia (low sodium levels).
C. Polyuria (increased urine output) is not seen in SIADH; instead, clients usually have oliguria or decreased urine output.
D. Increased thirst is more associated with diabetes insipidus, not SIADH, where water retention decreases thirst.
