The nurse is providing care for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which laboratory result requires immediate intervention?

  • A. Serum sodium of 140 mEq/L.
  • B. Serum potassium of 4.5 mEq/L.
  • C. Serum osmolality of 280 mOsm/kg.
  • D. Serum sodium of 130 mEq/L.
Correct Answer: D

Rationale: The correct answer is D: Serum sodium of 130 mEq/L. In SIADH, there is excess release of antidiuretic hormone leading to water retention and dilutional hyponatremia. A serum sodium level of 130 mEq/L indicates severe hyponatremia, which can result in neurological symptoms, such as confusion, seizures, and coma. Therefore, immediate intervention is required to prevent further complications. Choice A, a serum sodium of 140 mEq/L, is within the normal range and does not require immediate intervention. Choice B, serum potassium of 4.5 mEq/L, is also within the normal range and is not directly related to SIADH. Choice C, serum osmolality of 280 mOsm/kg, is a measure of the concentration of solutes in the blood and may not be the most critical parameter to address in a client with SIADH and severe hyponatremia.
