A hospitalized child has been diagnosed with SIADH (syndrome of inappropriate antidiuretic hormone), a complication of his meningitis. The nurse would expect this child's labs to show:
1. Hypernatremia.
2. Hyperglycemia.
3. Hyponatremia.
4. Hypocalcemia.
3
Rationale:
1. Hypernatremia is seen with DI, not SIADH.
2. Hyperglycemia is not related to SIADH.
3. SIADH is associated with increased permeability in distal renal tubes, leading to water intoxication and low sodium.
4. Hypocalcemia is not seen with SIADH.
