A nurse is providing education to a client newly diagnosed with leukemia. The client asks, "Is leukemia a genetic condition?" How should the nurse respond?
"Leukemia is always caused by inherited genetic mutations."
"There is no known genetic link to the development of leukemia."
"While genetic factors can play a role, leukemia is mainly caused by environmental factors."
"Some cases of leukemia may have genetic causes, but not all."
The Correct Answer is D
A) This choice is incorrect because leukemia is not always caused by inherited genetic mutations. While genetic factors can contribute to the development of some types of leukemia, it is not the only cause.
B) This choice is incorrect because there are known genetic links to certain types of leukemia. For example, some forms of leukemia, such as chronic myeloid leukemia (CML), are associated with specific genetic mutations.
C) This choice is incorrect because genetic factors and environmental factors can both play a role in the development of leukemia. Some cases may be influenced more by genetic factors, while others may be influenced more by environmental factors.
D) This choice is correct. Leukemia can have various causes, including genetic mutations, exposure to certain environmental factors (e.g., radiation, certain chemicals), and viral infections. While some cases may have a genetic basis, others may be triggered by environmental factors or have an unknown cause.

Correct Answer is C
Explanation
A) This choice is incorrect because leukemia does not result from an overproduction of platelets. Leukemia involves an overproduction of abnormal white blood cells.
B) This choice is incorrect because leukemia is not caused by the body's immune system attacking healthy white blood cells. Instead, it involves the uncontrolled growth of abnormal white blood cells.
C) This choice is correct. Leukemia is characterized by genetic mutations in the bone marrow cells, particularly in the stem cells that produce white blood cells. These mutations lead to uncontrolled growth and proliferation of abnormal white blood cells, interfering with the normal production of other blood cells.
D) This choice is incorrect because an imbalance of red blood cells would not trigger the overproduction of white blood cells. Leukemia is specifically a disorder of white blood cell proliferation.
Correct Answer is D
Explanation
A) This choice is incorrect because impaired wound healing is not a typical cause of enlarged gums and bleeding in leukemia.
B) This choice is incorrect because a hyperactive immune response is not directly related to oral symptoms in leukemia.
C) This choice is incorrect because overproduction of saliva is not a typical cause of enlarged gums and bleeding in leukemia.
D) This choice is correct. Enlarged gums (gingival hypertrophy) and bleeding from the gums are characteristic oral symptoms of acute leukemia. Leukemic cells can infiltrate the gums and oral tissues, leading to inflammation, bleeding, and gum enlargement.
