Question

Quizplus · Accepted Answer

ADH (antidiuretic hormone) regulates the amount of water reabsorbed by the kidneys, therefore, a deficiency in ADH production would result in decreased water reabsorption and increased urine volume. Option A (Increased blood volume) is incorrect because decreased ADH production would not have an effect on blood volume. Option B (Increased urine osmolality) is incorrect because ADH deficiency would actually lead to decreased urine osmolality due to decreased reabsorption of water, resulting in dilute urine. Option D (Increased arterial vasoconstriction) is incorrect because ADH deficiency would not affect arterial vasoconstriction.
