What is the primary cause of diabetes insipidus (DI)?
Overproduction of antidiuretic hormone (ADH).
Hyposecretion of antidiuretic hormone (ADH).
Hypersecretion of aldosterone.
Impaired function of the thyroid gland.
The Correct Answer is B
Diabetes insipidus is primarily caused by the hyposecretion or inadequate release of antidiuretic hormone (ADH), also known as vasopressin. ADH is responsible for regulating water balance by promoting water reabsorption in the kidneys.
Incorrect choices:
a. This choice is incorrect. Overproduction of ADH would lead to excessive water reabsorption and concentrated urine, which is not characteristic of diabetes insipidus.
c. This choice is incorrect. Hypersecretion of aldosterone would lead to sodium retention and increased fluid volume, which is not characteristic of diabetes insipidus.
d. This choice is incorrect. Impaired function of the thyroid gland would lead to thyroid-related disorders, not diabetes insipidus.

Explanation
Hypernatremia, or elevated sodium levels, is a common laboratory finding in clients with diabetes insipidus due to the excessive loss of water in urine.
Incorrect choices:
a. This choice is incorrect. Elevated urine specific gravity is not typically seen in diabetes insipidus; instead, urine specific gravity is often diluted.
c. This choice is incorrect. Low serum osmolality is not characteristic of diabetes insipidus, which is associated with concentrated serum.
d. This choice is incorrect. Hypouricemia refers to low levels of uric acid and is not directly related to diabetes insipidus.
Correct Answer is B
Explanation
The kidneys are the main target organ affected by the hyposecretion of antidiuretic hormone (ADH) in diabetes insipidus. ADH normally acts on the kidneys to promote water reabsorption and concentrate urine. In diabetes insipidus, the lack of ADH results in excessive urine production and dilute urine.
Incorrect choices:
a. This choice is incorrect. The liver is not the primary target organ affected by ADH in diabetes insipidus.
c. This choice is incorrect. The pancreas is not the primary target organ affected by ADH in diabetes insipidus.
d. This choice is incorrect. The heart is not the primary target organ affected by ADH in diabetes insipidus.
