SIADH

Practice

Etiology / Pathophysiology

  • Excess ADH from CNS disease, lung disease, medications, or malignancy.
  • Water retention dilutes sodium and creates concentrated urine.

Medications

Nursing actions

  • Monitor neuro status, sodium, intake/output, daily weight, and seizure risk.
  • Implement fluid restriction if ordered.
  • Use seizure precautions for severe hyponatremia.

Complications

  • Seizures
  • Cerebral edema
  • Falls

NCLEX cues

  • Low sodium, low serum osmolality, concentrated urine.
  • Weight gain without edema can occur.

Memory hooks

  • SIADH: too much water holds on, sodium diluted.

Labs / Diagnostics

  • Sodium
  • Serum osmolality
  • Urine osmolality
  • Urine specific gravity
