Which condition is typically associated with elevated urine chloride due to diuretic use?

Explanation:
When diuretics are in play, the kidneys excrete more chloride. Diuretics block NaCl reabsorption in parts of the nephron, increasing chloride delivery to the distal tubule and promoting chloride loss in the urine. In metabolic alkalosis, a high urine chloride points to diuretic use (as opposed to chloride depletion from vomiting, which typically gives a low urine chloride). So elevated urine chloride is a hallmark of diuretic-induced changes. Timing matters: recent diuretic dosing usually yields a clearly high urine chloride.
