Answer 1 is incorrect because this is a measure of urine concentration, which provides the practitioner information regarding the child's degree of fluid retention from excessive ADH production. Answer 2 is correct because obtaining a blood glucose level is not expected for a child diagnosed with SIADH since the priority measures involve blood and urine osmolality. Blood glucose is a likely laboratory test in a child with diabetes insipidus. Answer 3 is incorrect because a child with SIADH should be monitored closely for hyponatremia due to abnormal fluid retention. Answer 4 is incorrect because this is a measure of urine concentration, which provides the practitioner information regarding the child's degree of fluid retention from excessive ADH production.
