A 7-year-old child with hemophilia A is brought to the emergency department after falling from a bicycle. Which assessment finding would be the nurse's highest priority concern?

In hemophilia A, the primary concern is internal bleeding, particularly intra-abdominal bleeding which can be life-threatening. Abdominal pain with guarding and rigidity indicates potential internal hemorrhage.

This question evaluates critical thinking about priority assessment after trauma in a child with hemophilia A. Hemophilia A is a hereditary bleeding disorder caused by deficiency of coagulation factor VIII, leading to prolonged bleeding time and increased bleeding risk.

The correct answer focuses on recognizing signs of internal bleeding, especially intra-abdominal bleeding. When a child with hemophilia sustains trauma to the trunk area, intra-abdominal bleeding is a life-threatening emergency. Increasing abdominal pain accompanied by guarding (involuntary muscle contraction) and rigidity (boardlike abdomen) are classic signs of peritoneal irritation due to blood accumulation. This can lead to hypovolemic shock and death if not promptly recognized and treated.

Children with hemophilia have a significantly higher risk of serious internal bleeding than external bleeding, because internal bleeding can continue undetected until the child becomes hemodynamically unstable. Such assessment findings require immediate intervention including coagulation factor VIII replacement therapy, intravenous access, and possible surgical intervention.

This scenario emphasizes the critical nursing skill of recognizing subtle but dangerous signs of internal bleeding in high-risk patients. Nurses must understand that even minor trauma can cause major internal bleeding in hemophilia patients, and that abdominal signs take priority over more obvious external injuries.
