A Deficiency of ADH,called Diabetes Insipidus,is Characterized By

Question

A deficiency of ADH,called diabetes insipidus,is characterized by
A) glucosuria and an osmotic diuresis.
B) polyuria and polydipsia.
C) Kussmaul respirations and hyperventilation.
D) edema formation and sodium retention.

Accepted Answer

A deficiency of ADH leads to an inability of the kidneys to reabsorb water, resulting in excessive urine production (polyuria) and a corresponding increase in thirst (polydipsia). This is the hallmark of diabetes insipidus. Glucosuria and an osmotic diuresis are seen in diabetes mellitus, not diabetes insipidus. Kussmaul respirations and hyperventilation are associated with metabolic acidosis, not ADH deficiency. Edema formation and sodium retention are associated with excess ADH, not deficiency.
