Correct answer: E — IV normal saline bolus 20 mL/kg

Severe dehydration with signs of compensated shock requires immediate IV fluid resuscitation with a 20 mL/kg bolus of 0.9% normal saline. This may be repeated if needed. Once stabilised, ongoing deficit replacement should be calculated and administered.
