Hemophilia
Hemophilia ( 15 Questions)
Which response by the nurse is accurate?
Hemophilia A is indeed caused by a mutation in the F8 gene, which encodes factor VIII. Factor VIII is essential for blood clotting, and mutations in this gene lead to a deficiency or dysfunction of factor VIII, resulting in hemophilia A. This response provides accurate information about the cause of the condition.
Hemophilia A is not caused by a mutation in the F9 gene, which encodes factor IX. Factor IX deficiency is associated with hemophilia B, not hemophilia A. This statement is incorrect.
Hemophilia A is not caused by a mutation in the Y chromosome. As mentioned earlier, it is caused by a mutation in the F8 gene on the X chromosome. This statement is incorrect.
Hemophilia A is not caused by a deficiency of vitamin K. Vitamin K deficiency can lead to bleeding disorders, but it is not the cause of hemophilia A. This statement is incorrect.
Choice A rationale:
Hemophilia A is indeed caused by a mutation in the F8 gene, which encodes factor VIII.
Factor VIII is essential for blood clotting, and mutations in this gene lead to a deficiency or dysfunction of factor VIII, resulting in hemophilia A.
This response provides accurate information about the cause of the condition.
Choice B rationale:
Hemophilia A is not caused by a mutation in the F9 gene, which encodes factor IX.
Factor IX deficiency is associated with hemophilia B, not hemophilia A.
This statement is incorrect.
Choice C rationale:
Hemophilia A is not caused by a mutation in the Y chromosome.
As mentioned earlier, it is caused by a mutation in the F8 gene on the X chromosome.
This statement is incorrect.
Choice D rationale:
Hemophilia A is not caused by a deficiency of vitamin K.
Vitamin K deficiency can lead to bleeding disorders, but it is not the cause of hemophilia A.
This statement is incorrect.
