Answer

With hyperkalemic dRTA, entities amenable to intervention, such as obstructive uropathy, must be identified. In general, distal sodium delivery is increased if patients increase their ingestion of dietary salt, taking into account that many of these patients have concomitant cardiorenal compromise.

Fluid overload can be overcome with the addition of furosemide to a high-salt diet. This combination encourages distal delivery of sodium by rendering the collecting tubule impermeable to chloride, and it increases the exchange of sodium for hydrogen and potassium.
