Nephrogenic diabetes insipidus is evated plasma aldosterone level (secondary to volume characterized by increased output of dilute urine. Plasma osmolality is on the high side of the nor- pokalemia or hyperkalemia. The plasma AVP level will fall because of vol- mellitus because there is no glucose in the urine and ume expansion and cardiovascular stretch receptor in- the urine is very dilute. The plasma aldosterone level produce very dilute urine because Na reabsorption is will be low because of inhibited release of renin and inhibited. Neurogenic diabetes insipidus is unlikely be- less angiotensin II formation. The plasma ANP level cause the plasma AVP level is reduced in this case. A mary polydipsia produces output of a large volume of large part of the infused isotonic saline will be filtered dilute urine, but plasma osmolality and AVP levels are through capillary walls into the interstitial fluid. Na is the major osmotically active creased, but these should promote Na excretion, not solute in the ECF and is the major determinant of the lead to Na retention by the kidneys. A decrease in ef- amount of water in and, hence, volume of this com- fective arterial blood volume is the best explanation for partment. Although the plasma osmolality is ex- traordinarily high, the plasma Na , glucose, and BUN Chapter 25 are normal. This indicates the presence of another solute (it could be ethanol) in the plasma.
