Question 1 of 5
A nurse is caring for a child who has hemophilia. The nurse should expect abnormal results in which of the following diagnostic tests?
Correct Answer: D
Rationale: The correct answer is D: Partial thromboplastin time (PTT). In hemophilia, there is a deficiency in specific clotting factors, leading to prolonged PTT due to impaired intrinsic pathway function. A: Fibrinogen level is normal in hemophilia as it is not affected by clotting factor deficiencies. B: Hemoglobin level is unrelated to hemophilia and reflects oxygen-carrying capacity of blood. C: Prothrombin time (PT) evaluates the extrinsic pathway, which is typically normal in hemophilia.
Therefore, the abnormal result is in PTT, making it the correct choice.
