What pharmacologic treatment can be used to treat Diabetes insipidus?

A. This option is incorrect because impaired sodium excretion by the kidneys does contribute to increased peripheral vascular resistance and hypertension.

B. Impaired sodium excretion by the kidneys can lead to fluid retention, which increases blood volume. This results in increased peripheral vascular resistance, a key factor in the development of hypertension.

C. Overstimulation of the parasympathetic nervous system typically causes a reduction in heart rate and vasodilation, which would generally lower blood pressure, not contribute to hypertension.

D. The renin-angiotensin-aldosterone system plays a crucial role in regulating blood pressure. Reduced secretion of renin, angiotensin, and aldosterone would not contribute to increased peripheral vascular resistance. In fact, these systems typically work to raise blood pressure when needed.

A. While high blood glucose levels can affect nerve function, excessive glucose exposure does not specifically target the brain and spinal cord in a way that causes neuropathy.

B. Neuropathy in diabetes is not caused by the inability to provide glucose to the brain and spinal cord, but rather by the effects of high blood glucose levels on peripheral nerves.

C. Infection in the nerves is not the primary cause of diabetic neuropathy, although infection can occur in diabetic patients due to poor circulation and immune system impairment.

D. Chronic high blood glucose levels can cause thickening of blood vessels, leading to poor circulation (ischemia) that deprives nerves of oxygen and nutrients, ultimately causing nerve damage. This is the primary cause of diabetic neuropathy.
