AThe kidneys are secreting extra bicarbonate
BThe glomeruli are leaking plasma proteins
CThe body is using fat rather than glucose
DThe ureters are obstructed by a large stone
Answer & Solution
Correct answer: C. The body is using fat rather than glucose
1. Ketones are byproducts of fat metabolism.
2. Their appearance in urine means fat is being burned in preference to glucose.
3. In diabetes mellitus glucose is abundant but cannot enter cells without insulin action, so fat is used instead.
4. A severe dietary shortage of protein or carbohydrate can produce the same finding.
5. Protein leaking into the urine points at the glomerulus and has nothing to do with ketone production.
