Diabetes Insipidus correcty answerAntidiuretic hormone is
not secreted adequately, or the kidney is resistant to its effect. The *serum
sodium is often elevated* due to excess free water losses.
In diabetes insipidus, your blood glucose levels are normal,
but your kidneys can't properly concentrate urine.
Cardiac Valve Disease Process correcty answerIn heart valve
disease, one or more of the valves in your heart doesn't work properly.
Regurgitation (or leakage of the valve). When the valve(s) do not close
completely, it causes blood to flow backward through the valve. This reduces
forward blood flow and can lead to volume overload in the heart.
Stenosis (or narrowing of the valve). When the valve(s)
opening becomes narrowed, it limits the flow of blood out of the ventricles or
atria. The heart is forced to pump blood with increased force to move blood
through the narrowed or stiff (stenotic) valve(s).
