A nurse is caring for a client with a urine specific gravity of less than 1.005, polyuria, and nocturia. The nurse recognizes that which of the following physiologic findings is the likely cause?
Increased insulin production
Increased adrenocorticotropic hormone (ACTH)
Low levels of T3, T4
Insufficient antidiuretic hormone (ADH)
The Correct Answer is D
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.

Correct Answer is B
Explanation
A. Quadriplegia, or tetraplegia, is typically associated with injuries at or above the C4 level, not T2-T3.
B. A T2-T3 spinal cord injury can lead to loss of sensation and motor function below the level of injury, affecting the thoracic region and lower body.
C. Hemiplegia, which refers to paralysis on one side of the body, is typically due to brain injuries or strokes, not spinal cord injuries.
D. While bladder control may be affected, the most direct impact of T2-T3 injury is the loss of sensation and motor function below that level.
Correct Answer is B
Explanation
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.
