<prompt> Pseudohyponatremia is found in all of the following EXCEPT:Severe hyperlipemiaExtreme hyperproteinemiaAldosterone excessHypothyroidism  <response>: Hyponatremia is defined as a plasma level less than 135 meqL. Most often it reflects excess water, rather than less of Na, in the plasma. Hence, plasma becomes hypo-osmolar in most instances. Hyponatremia with a normal plasma osmolality is the so-called pseudohyponatremia. It occurs when plasma lipids or proteins are greatly elevated options A B. The proteins or lipids do not increase plasma osmolality significantly. However, they occupy a significant volume of the plasma; and hence the measured in the entire plasma is low. Hyponatremia with normal body Na content is seen in hypothyroidism option D, coisol deficiency, and SIADH. Hyponatremia with increased total body Na is seen in edematous states, such as congestive hea failure, cirrhosis of liver, and nephrotic syndrome. Hyponatremia with increased plasma osmolality is seen in hyperglycemia associated with uncontrolled DM. In such a condition, the high plasma glucose causes water to move by osmosis, from cells into plasma. The excess water in ECF leads to hyponatremia.
