In the case of SIADH, what does the nurse expect in terms of findings?

  1. SIADH
  2. Diabetes insipidus
  3. Cushing’s disease
  4. Acromegaly
Show answer and explanation

Correct answer: Diabetes insipidus

After pituitary surgery, damage to the posterior pituitary can cause ADH deficiency leading to central diabetes insipidus, with large volumes of dilute urine and intense thirst. SIADH would cause water retention; Cushing's and acromegaly do not cause polyuria.
