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)

Answer and Explanation

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.

A. Feeling fatigued B. Decreased thyroxine C. Decreased thyroid-stimulating hormone. D. Bradycardia and hypotension

Correct Answer is C

Explanation

A. Feeling fatigued is not indicative of a therapeutic response; rather, patients should experience increased energy levels with appropriate therapy.
B. Decreased thyroxine levels are not the primary goal of levothyroxine therapy, which aims to normalize thyroid hormone levels in the body.
C. Decreased thyroid-stimulating hormone (TSH) levels indicate that the body is responding well to levothyroxine, as TSH production decreases when thyroid hormone levels are adequate.
D. Bradycardia and hypotension are not desired effects of levothyroxine and indicate potential under-treatment or other issues rather than a therapeutic response.
