A nurse is assessing a client who had a craniotomy and has developed syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following manifestations should the nurse anticipate?
Weight loss
Oliguria
Hypernatremia
Increased thirst
The Correct Answer is B
A) SIADH leads to water retention due to excessive secretion of antidiuretic hormone (ADH), resulting in weight gain rather than weight loss.
B) SIADH causes the kidneys to retain water, leading to decreased urine output (oliguria) and concentrated urine.
C) SIADH typically results in dilutional hyponatremia due to water retention, not hypernatremia.
D) In SIADH, the body retains water excessively, leading to decreased serum osmolality and suppression of thirst, rather than increased thirst.

Correct Answer is C
Explanation
A. Metabolic Acidosis, Uncompensated, is ruled out because the elevated PaCO2 and low pH indicate a respiratory problem rather than a metabolic one.
B. Respiratory Alkalosis. Partially Compensated is ruled out because the pH and PaCO2 levels are both abnormal and indicate acidosis rather than alkalosis.
C. The low pH (acidosis) along with the high PaCO2 indicate respiratory acidosis, and there is no evidence of compensation by the kidneys (normal HCO3).
D. Metabolic Alkalosis. Partially Compensated, is ruled out because the pH is low (acidosis) rather than high (alkalosis), and the PaCO2 is elevated, suggesting a respiratory problem rather than a metabolic one.
