Answer: A
In educating the client and the client's parents regarding sickle cell disease, the nurse will state that the disorder is transmitted as an autosomal recessive genetic defect. If both parents have the trait, then with each pregnancy, the risk of having a child with the disease is 25%, not 50%. The sickle cell gene may have originated to protect against lethal forms of malaria. In African-Americans, sickle cell disease occurs in 1 out of every 500 births.
