Which of the following findings does a patient with hemophilia present?

A patient with hemophilia typically presents with an increased clotting time. Hemophilia is a genetic disorder that affects the blood's ability to clot due to deficiencies in specific clotting factors, most commonly factor VIII or factor IX. This deficiency leads to prolonged time for blood to coagulate, as the necessary components for the clotting cascade are insufficient.

Increased clotting time is a key characteristic of hemophilia because it indicates how long it takes for blood to form a stable clot in response to injury. In patients with this condition, the tests that typically measure clotting time, like the activated partial thromboplastin time (aPTT), will show a prolonged result, reflecting the underlying issue with factor production.

On the other hand, prothrombin time is usually not affected in hemophilia, and thus it does not tend to be prolonged. Bleeding time can also be normal in hemophilia unless significant platelet dysfunction is present. Additionally, a patient with hemophilia would not typically present with an increased platelet count, as the pathology is related to clotting factors rather than platelet production or function.
