Question

A nurse is reviewing the laboratory report of an adolescent client who had hemophilia A. Which of the following laboratory results should the nurse expect?

A.aPTT 110 seconds
B.Coagulating factor VIII 50%
C.Coagulating factor IX 75%
D.PT 14 seconds

Answer 1

An adolescent client with hemophilia A should expect an extended aPTT, with A.aPTT 110 seconds being the correct laboratory result among the options provided.

Step-by-step explanation:

The laboratory result that a nurse should expect for an adolescent client with hemophilia A is an extended activated partial thromboplastin time (aPTT). The correct answer to the question would be A.aPTT 110 seconds. Hemophilia A is characterized by the inability to synthesize sufficient amounts of coagulating factor VIII, which results in prolonged bleeding times due to impaired blood clotting. Option B cannot be correct since individuals with hemophilia A have significantly lower than 50% factor VIII activity, and Option C pertains to hemophilia B, which involves factor IX deficiency. Option D represents prothrombin time (PT) which is usually not affected in hemophilia A.
