A pediatric nurse health educator provides a teaching session to the nursing staff regarding hemophilia. Which of the following information regarding this disorder would the nurse plan to include in this discussion?
Hemophilia B results from a deficiency in clotting factor VIII
Males inherit hemophilia from their mothers
Females inherit hemophilia from their fathers
Hemophilia is a Y linked disorder
The Correct Answer is B
A. Hemophilia B results from a deficiency in clotting factor VIII. Hemophilia B results from a deficiency in clotting factor IX. Hemophilia A results from a deficiency in clotting factor VIII.
B. Males inherit hemophilia from their mothers. Hemophilia is an X-linked recessive disorder, meaning males inherit the defective gene from their carrier mothers.
C. Females inherit hemophilia from their fathers. Females can be carriers if they inherit the
defective gene from their mother, but they generally do not inherit the disease itself from their fathers due to the X-linked recessive inheritance pattern.
D. Hemophilia is a Y linked disorder. Hemophilia is not Y-linked; it is an X-linked recessive disorder.
