Passage / Scenario
Pediatric client with hemophilia.The nurse analyzes the laboratory results of a pediatric client with hemophilia. The nurse understands which result will most likely be abnormal in this client?
Correct answer
A
Rationale
The correct answer is A: Partial thromboplastin time (PTT). In hemophilia, there is a deficiency in clotting factors, leading to prolonged PTT. Hemoglobin level (B), platelet count (C), and hematocrit level (D) are typically normal in hemophilia as they are more related to red blood cells and platelets, not clotting factors. PTT specifically assesses the intrinsic pathway of coagulation, which is affected in hemophilia. This abnormality is not reflected in the other choices.
