Which finding would most strongly indicate the need for intervention in hyperemesis gravidarum?

Which finding would most strongly indicate the need for intervention in hyperemesis gravidarum?

• A. Mild nausea.
• B. Normal appetite.
• C. Decreased urine output.
• D. Ketones in urine.

Answer: (D)

The key idea is that ketones in the urine signal metabolic distress from hyperemesis gravidarum. When vomiting is severe and intake is inadequate, the body shifts to fat breakdown for energy, producing ketones that appear in urine. This ketonuria reflects a significant caloric deficit and dehydration, indicating the need for urgent management—typically IV fluids with electrolyte replacement, antiemetics, and nutritional support to prevent maternal and fetal complications. Mild nausea or normal appetite don’t show this level of metabolic strain, and while decreased urine output can occur with dehydration, it doesn’t specifically demonstrate the ongoing catabolic state that ketones reveal.
