After a head injury, a client develops a deficiency of antidiuretic hormone (ADH). What should the nurse consider before assessing the patient about the response to secretion of ADH?

  • A. Serum osmolality increases
  • B. Urine concentration decreases
  • C. Glomerular filtration decreases
  • D. Tubular reabsorption of water increases
Correct Answer: B

Rationale: ADH deficiency (diabetes insipidus) post-head injury causes dilute urine (B) due to reduced water reabsorption. Osmolality increases (A) is a result, not a cause. GFR (C) isn't primarily affected. Reabsorption (D) decreases. B is correct. Rationale: Low ADH leads to polyuria with low urine concentration, a key assessment in DI, per endocrine trauma care.
