Which form of leukemia demonstrates the presence of the Philadelphia chromosome?

CML (chronic myeloid leukemia)

(T/F) The anemia resulting from a deficiency of either vitamin B 12 (cobalamin) or folate is caused by a disruption in DNA synthesis of the blast cells in the bone marrow that produces very large abnormal bone marrow cells called megaloblasts.

True

(T/F) The liver is responsible for the synthesis of coagulation factors, with the exception of part of VIII.

True

(T/F) The only known curative treatment for CML is allogeneic bone marrow transplantation from a suitable donor.

True

(T/F) Two of the most serious oncology emergencies associated with non-Hodgkin lymphoma are obstruction of the superior vena cava and compression of the spinal cord.

chemotherapy

The final step in clot formation is

clot retraction

Patients with immunodeficiency disorders are usually first identified because they

develop recurrent infections

Widespread activation of the clotting cascade secondary to massive trauma is called

disseminated intravascular coagulation (DIC)

The most effective therapy for anemia associated with kidney failure is

erythropoietin administration

The prothrombin time (PT) and INR (international normalized ratio) measure the integrity of

extrinsic pathway

Red blood cells differ from other cell types in the body, because they

have no cytoplasmic organelles

hyperlipidemia

The effects of histamine release include

increased vascular permeability

Venous obstruction leads to edema because it ________ pressure.

increases capillary hydrostatic

Disseminated intravascular coagulation may be treated with heparin therapy to

inhibit clotting factor consumption

Pernicious anemia is caused by a lack of

The primary source of erythropoietin is provided by the

kidney

Which causes vasoconstriction?

norepinephrine

A deficiency of von Willebrand factor impairs

platelet adhesion to injured tissue
