A nurse is caring for a school-age child who has appendicitis. For which of the following findings should the nurse monitor as a manifestation of a perforated appendix and report to the provider?

The correct answer is Choice B. Choice A rationale: Bradycardia is not typically associated with a perforated appendix. Instead, tachycardia (increased heart rate) may occur due to pain and infection-related systemic responses. Bradycardia could indicate other unrelated medical issues and should still be monitored. Choice B rationale: Elevated temperature is a key sign of infection and inflammation, which are common with a perforated appendix. The release of bacteria into the abdominal cavity can cause peritonitis, leading to fever as part of the body's immune response. Choice C rationale: Lethargy can be a nonspecific symptom and may occur in various conditions. While it can be associated with severe infection, it is not a definitive indicator of a perforated appendix. Monitoring for more specific signs, like fever and pain, is crucial. Choice D rationale: Decreased abdominal girth is unlikely and not indicative of a perforated appendix. Instead, an increase in abdominal girth due to fluid accumulation (ascites) or air (from perforation) would be more concerning and should be reported promptly.
