A school-age child in an emergency department has a 2-day history of nausea and vomiting and reports severe right lower quadrant pain. A nurse is preparing the child for an appendectomy. Which of the following statements by the child should the nurse find most concerning?

A. "I'm tired and want to take a nap." Common in sick children and not necessarily concerning in this context. B. "I am scared and I want to go home." Emotional response, typical in children facing surgery. C. "I am hungry and thirsty." Normal sensations and not indicative of the severity of the condition. D. "My belly doesn't hurt anymore." This statement suggests potential rupture or perforation of the appendix, which can lead to peritonitis and is a surgical emergency. A sudden relief of pain can indicate a worsening condition rather than improvement.
