A client with suspected leukemia is undergoing flow cytometry analysis. What is the primary purpose of this test in the diagnostic evaluation of leukemia?

A) This choice is incorrect because chemotherapy may cause a decreased platelet count, leading to a risk of bleeding, rather than increased blood clotting and thrombosis.

B) This choice is incorrect because chemotherapy does not typically cause elevated blood pressure and hypertension.

C) This choice is correct. Nausea, vomiting, and hair loss are common side effects of chemotherapy due to its effect on rapidly dividing cells, including hair follicles and cells lining the digestive tract.

D) This choice is incorrect because excessive bleeding and hemorrhage are not common side effects of chemotherapy in leukemia treatment.

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.
