Which intervention is a key component of the management plan for a client with diabetes insipidus (DI)?
Limiting fluid intake to 500 mL per day.
Administering hypertonic saline solution.
Encouraging excessive fluid consumption.
Administering desmopressin (DDAVP) as prescribed.
The Correct Answer is D
Desmopressin (DDAVP) is a synthetic form of antidiuretic hormone (ADH) that is commonly used to manage diabetes insipidus by increasing water reabsorption in the kidneys and reducing urine output.
Incorrect choices:
a. This choice is incorrect. Limiting fluid intake to 500 mL per day is not a typical management approach for diabetes insipidus. Adequate fluid intake is necessary to prevent dehydration.
b. This choice is incorrect. Administering hypertonic saline solution is not a standard treatment for diabetes insipidus and may worsen fluid and electrolyte imbalances.
c. This choice is incorrect. Encouraging excessive fluid consumption is not a suitable approach for managing diabetes insipidus, as it can exacerbate fluid loss.

Incorrect choices:
a. This choice is incorrect. The glucose tolerance test is used to diagnose diabetes mellitus, not diabetes insipidus.
c. This choice is incorrect. The water deprivation test is used to diagnose diabetes insipidus and assess the ability of the kidneys to concentrate urine.
d. This choice is incorrect. The desmopressin stimulation test involves administering synthetic ADH to differentiate between central and nephrogenic diabetes insipidus.
Correct Answer is B
Explanation
The posterior lobe of the pituitary gland, also known as the neurohypophysis, is responsible for producing and releasing antidiuretic hormone (ADH) in response to signals from the hypothalamus.
Incorrect choices:
a. This choice is incorrect. The hypothalamus produces ADH and releases it into the posterior pituitary for storage and release.
c. This choice is incorrect. The anterior lobe of the pituitary gland is responsible for producing and releasing other hormones, such as growth hormone and thyroid-stimulating hormone.
d. This choice is incorrect. The pineal gland is responsible for producing melatonin, a hormone that regulates sleep-wake cycles, and is not involved in ADH production.
