A client with a closed head injury demonstrates signs of syndrome of inappropriate antidiuretic hormone (SIADH). Which additional finding should the nurse expect to obtain?
Correct answer
A
Rationale
Weight gain of 2 pounds (0.91 kg) in one day is a sign of fluid retention, which occurs in SIADH due to excessive secretion of antidiuretic hormone (ADH). ADH causes the kidneys to reabsorb water and reduce urine output, leading to hyponatremia and hypervolemia.
