A nurse is reviewing the diagnostic tests of a client suspected of having leukemia. The laboratory report shows elevated levels of blast cells in the peripheral blood. Which test result supports the suspicion of leukemia?

A) This choice is incorrect because alcohol-based mouthwash can further irritate the mucosal lining and worsen mucositis. It should be avoided.

B) This choice is incorrect because ice chips and cold beverages may provide temporary relief, but pain medication is the priority intervention to manage severe mucositis and alleviate discomfort.

C) This choice is correct. Administering prescribed pain medications, such as topical analgesics or systemic pain relief, is essential in managing the severe pain associated with mucositis.

D) This choice is incorrect because spicy foods can aggravate mucositis and should be avoided to prevent further irritation of the mucosal lining.

A) This choice is incorrect because a bone marrow biopsy is not primarily performed to assess the client's platelet count. Platelet counts are typically obtained through a blood test.

B) This choice is incorrect because evaluating the effectiveness of chemotherapy is not the primary reason for performing a bone marrow biopsy in the diagnostic evaluation of leukemia. The biopsy is performed to determine the presence of cancerous cells in the bone marrow and aid in diagnosing leukemia.

C) This choice is correct. A bone marrow biopsy involves the collection of bone marrow samples to determine the presence of cancerous cells and assess cell morphology in the bone marrow. This information is crucial in diagnosing leukemia and determining the appropriate treatment plan.

D) This choice is incorrect because measuring the client's bone density is not the primary reason for performing a bone marrow biopsy.
