In diabetic ketoacidosis, what CVP reading would you expect indicating volume deficit?

Explanation:
Diabetic ketoacidosis typically causes significant loss of extracellular fluid through osmotic diuresis and sometimes vomiting, so the intravascular volume is reduced. Central venous pressure reflects preload; when volume is depleted, CVP drops. Among the given values, the lowest reading indicates volume deficit. A reading of about 1 mm Hg is low and consistent with hypovolemia, whereas higher values would suggest normal or increased preload. Therefore, the reading indicating volume deficit is the very low one.
