Which of the following is a characteristic feature of hemophilia?

A. Dusky mucous membranes are not typically associated with pernicious anemia.
B. A red tongue that is smooth and sore is a common finding in pernicious anemia due to vitamin B12 deficiency, which affects the epithelial cells of the tongue.
C. Shortness of breath on exertion can occur in many types of anemia but is not specific to pernicious anemia.
D. Dyspnea is also a common symptom in various anemias but is not as characteristic as the red, smooth, and sore tongue in pernicious anemia.

A. Prolonged bleeding or easy bruising is a characteristic feature of hemophilia, a genetic
disorder characterized by deficient or defective blood clotting proteins, leading to impaired blood clotting and prolonged bleeding after injury or trauma.
B. Excessive blood clotting is not a characteristic feature of hemophilia; rather, it is the opposite.
Hemophilia is characterized by a deficiency in clotting factors, which results in impaired clot formation.
C. Hemophilia does not typically result in increased platelet count. Platelets are involved in the initial stages of blood clotting, but hemophilia primarily affects clotting factor proteins.
D. Delayed wound healing is not a characteristic feature of hemophilia. Hemophilia primarily affects blood clotting, leading to prolonged bleeding, but it does not directly affect wound
healing processes.
