A nurse is caring for an infant who has gastroenteritis. Which of the following assessment findings should the nurse report to the provider?

A. Incorrect – A 24-hour fluid deficit of 30 mL is mild and does not require immediate intervention. B. Incorrect – Decreased appetite and irritability are common with gastroenteritis but not as concerning as dehydration. C. Incorrect – A temperature of 38°C (100.4°F) and pulse of 124/min are mild and expected with infection. D.
