Correct answer: E — Oral rehydration with small frequent sips of ORS

For moderate dehydration with some vomiting, oral rehydration with small frequent sips of ORS is the first-line approach. Vomiting is not a contraindication to ORT. If the child continues to vomit and cannot maintain oral intake, nasogastric rehydration is the next step before IV fluids. Australian guidelines emphasise ORT as first-line for moderate dehydration.
