The nurse is caring for a client who is on a low-carbohydrate diet. with this diet, there is decreased glucose available for energy and fat is metabolized for energy, resulting in an increased production of which substance in the urine?

The answer to this question would be: ketone

When the body metabolizes the fat, it would result in a ketone. The ketone will be excreted by the kidney and dumped in the urine.
An example of this condition is ketoacidosis in diabetic patient who doesn't get treatment. In this case, the cell cant use glucose as the insulin produced is not enough. This cause high number of fat metabolized to be ketone.
