patho ch 12 disorders of white blood cells

-more common in children than adults -B or T cells do not function or mature -Bone marrow greater than 20% lymphoblasts

Acute Lymphocytic Leukemia (ALL)

-anemia -blast cells may invade other tissues -bone marrow more than 20% blast cells of myeloid origin

Acute Myelogenous Leukemia (AML)

-most common leukemia in the u.s. -elderly individuals affected -B cells do not produce Igs (or just release low or mutated Igs) -bone marrow reveals small lymphocytes and greater than 30% ?

Chronic Lymphocytic Leukemia (CLL)

-overproduction of mature myeloid cells -total WBC may get as high as 100,000 cells -progressive phases have loss of neutrophil differentiation

Chronic Myelogenous Leukemia (CML)

A 65-year-old patient reports night sweats and weight loss. The complete blood count report shows that she has lymphocytosis. The total white blood cell count is 23,000 microliters. On diagnosis, the bone marrow of the patient is infiltrated with small lymphocytes. What should the nurse suspect based on the information? Acute lymphocytic leukemia Chronic lymphocytic leukemia Acute myelogenous leukemia Chronic myelogenous leukemia

Which of the following statements are true? Select all that apply. Multiple myeloma is a condition of T cells. Hodgkin's lymphoma presents with Reed-Sternberg cells. Hodgkin's lymphoma is a malignancy of B cells. Non-Hodgkin's lymphoma is a malignancy of T, B, or natural killer cells. Acute lymphocytic leukemia is more common in children.

Hodgkin's lymphoma presents with Reed-Sternberg cells. Hodgkin's lymphoma is a malignancy of B cells. Non-Hodgkin's lymphoma is a malignancy of T, B, or natural killer cells. Acute lymphocytic leukemia is more common in children.

A patient is being tested for a hematological neoplasm. Which finding(s) would be present in the patient if he tests positive for the neoplasm? Select all that apply. Increased number of red blood cells Increased oxygen carrying capacity Increased number of platelets Increased proliferation of abnormal lymphocytes Increased clotting time

Increased proliferation of abnormal lymphocytes Increased clotting time

A patient comes to the hospital and reports night sweats as a result of acute myelogenous leukemia. Which other effect does the condition have on the patient? Select all that apply. It increases the production of blood cells. It decreases the number of myeloid cells to below 10%. It increases levels of immature lymphocytes. It increases the incidence of anemia. It increases immature myeloid cells.

It increases the incidence of anemia. It increases immature myeloid cells.
