A nurse is assessing a client with leukemia and finds multiple ecchymoses (bruises) of varying sizes on the skin. The client mentions minimal trauma to the affected areas. What is the most likely cause of these ecchymoses?
Impaired bone density
Deficiency of clotting factors
Increased production of platelets
Elevated levels of red blood cells
The Correct Answer is B
A) This choice is incorrect because impaired bone density would not directly cause ecchymoses on the skin. It might lead to an increased risk of fractures, but not bruising.
B) This choice is correct. Ecchymoses (bruises) of varying sizes with minimal trauma are common in leukemia due to a deficiency of platelets and impaired clotting factors in the blood. Leukemia can lead to decreased platelet production and clotting abnormalities, resulting in easy bleeding and bruising.
C) This choice is incorrect because increased production of platelets would improve clotting abilities and reduce the risk of ecchymoses.
D) This choice is incorrect because elevated levels of red blood cells would not directly cause ecchymoses on the skin. It may lead to other symptoms like increased blood viscosity.

Correct Answer is D
Explanation
A) This choice is incorrect because a family history of diabetes is not a known risk factor for leukemia. While genetics can play a role in some leukemia cases, diabetes is not associated with leukemia development.
B) This choice is incorrect because exposure to asbestos is a risk factor for certain types of cancer, such as lung cancer and mesothelioma, but it is not a primary risk factor for leukemia.
C) This choice is incorrect because while autoimmune disorders can affect the immune system, they are not a known risk factor for leukemia.
D) This choice is correct. A previous diagnosis of lymphoma is a significant risk factor for developing leukemia. Lymphoma and leukemia are both types of blood cancers, and individuals with a history of lymphoma have an increased risk of developing leukemia.
Correct Answer is C
Explanation
A) This choice is correct. Using a soft-bristled toothbrush helps prevent gum bleeding and trauma to the oral mucosa, reducing the risk of infection in clients with low platelet counts.
B) This choice is incorrect because during leukemia treatment, outdoor activities may expose the client to potential sources of infection. It is better to avoid crowded places and maintain good hand hygiene.
C) This choice is correct. Raw fruits and vegetables may carry bacteria and pathogens, and the client with leukemia, particularly those undergoing chemotherapy, is at a higher risk of infection. It is advised to thoroughly wash and cook fruits and vegetables before consumption.
D) This choice is incorrect because although emotional support from friends and family is essential, it is crucial to limit the number of visitors to reduce the risk of exposure to potential infections.
