Corticosteroids

Answer and Explanation

The Correct Answer is B

A. Hormone replacement is generally used to supplement deficiencies rather than inhibit excess hormone release.
B. Dopamine agonists, such as bromocriptine, are used to inhibit the release of growth hormone from the anterior pituitary, which is beneficial in treating acromegaly, a condition caused by excess growth hormone.
C. Levothyroxine is a thyroid hormone replacement and is not effective in controlling pituitary hormone release.
D. Corticosteroids do not inhibit growth hormone release and are typically used to manage inflammation rather than for pituitary hormone control.

Explanation

A. In SIADH, excess ADH causes water retention and hyponatremia; fluid restriction helps to prevent further dilution of sodium and manage fluid balance.

C. Increasing oral intake would worsen fluid overload and hyponatremia.
D. Rapid IV fluid infusion can exacerbate the client’s condition by increasing fluid volume further.

A. Increased insulin production B. Increased adrenocorticotropic hormone (ACTH) C. Low levels of T3, T4 D. Insufficient antidiuretic hormone (ADH)

Correct Answer is D

Explanation

A. Increased insulin production would not cause polyuria and low specific gravity urine; rather, hyperglycemia from lack of insulin can cause high specific gravity due to glucose in urine.
B. Increased ACTH affects cortisol production but is not directly related to urine concentration or polyuria.
C. Low T3 and T4 levels are associated with hypothyroidism, which typically does not cause polyuria or decreased specific gravity.
D. Insufficient ADH, as seen in diabetes insipidus, leads to the inability to concentrate urine, resulting in a low specific gravity, polyuria, and nocturia due to excessive water loss.
