WCU PATHO 370 MIDTERM ASSESSMENT TEST 2025 An important mediator of a type I hypersensitivity reaction is Histamine. Patients with immunodeficiency disorders are usually first identified because they develop recurrent infections. Risk factors for atherosclerosis include Hyperlipidemia. The principle Ig mediator of type I hypersensitivity reactions is IgE. A 58-year-old woman is seen in the clinic for reports of severe back pain. Her chest x ray demonstrates generalized bone demineralization and compression fracture. Blood studies demonstrate elevated calcium levels. The most likely diagnosis is myeloma. The Philadelphia chromosome is a balanced chromosome translocation that forms a new gene called bcr-abl. A serious complication of deep vein thrombosis is pulmonary embolus. Which is not a manifestation of acute arterial obstruction? Purpura RhoGAM (an Rh antibody) would be appropriate in an Rh-_____ woman with an _____ Rh-_____ antibody titer carrying an Rh-_____ fetus. negative; negative; positive Venous obstruction leads to edema because it ________ pressure. increases capillary hydrostatic A primary effector cell of the type I hypersensitivity response is mast cells. The patient is a 12-year-old boy diagnosed with acute lymphoid leukemia (ALL). As part of treatment, the patient must undergo several weeks of chemotherapy. The most serious complication of chemotherapy is infection. While in the hospital for management of acute lymphoid leukemia (ALL), a patient develops severe thrombocytopenia. The most appropriate action for this condition is activity restriction. The hypersensitivity reaction that does not involve antibody production is type PATHO 370 PATHO 370 I II III IV IV When a patient is struck in the eye by a baseball, the result is redness and swelling. This increase in blood flow to a localized area is called hyperemia. Renal insufficiency is a common complication of which disease? Myeloma Burkitt lymphoma is most closely associated with Epstein-Barr virus. The liver is responsible for the synthesis of coagulation factors, with the exception of part of VIII. True or False True Tissues are able to autoregulate their rate of blood flow by controlling vascular resistance. Which is not considered to be a risk factor for thrombus formation? Thrombocytopenia What is necessary for red blood cell production? Iron Vaccination for pneumococcal pneumonia should be performed before 1 year of age in patients with sickle cell anemia. True or False False A 3-year-old boy who exhibits prolonged bleeding after minor trauma and a prolonged aPTT, but a normal platelet count, is likely to be diagnosed with Hemophilia. A newborn has melena, bleeding from the umbilicus, and hematuria. The newborn most likely experiencing Vitamin K deficiency bleeding. The cause of the most common form of anemia is Iron deficiency. The most effective therapy for anemia associated with kidney failure is Erythropoietin administration. A laboratory test finding helpful in confirming the diagnosis of iron-deficiency anemia is Elevated total iron-binding capacity. PATHO 370 PATHO 370 The most appropriate treatment for secondary polycythemia is Measured to improve oxygenation. Patients who experience anemic episodes when exposed to certain drugs most likely have Glucose-6-phosphate dehydrogenase deficiency. The activated partial thromboplastin time (aPTT) is a measure of the integrity of The intrinsic pathway. Hemophilia B is also known as Christmas disease. True or False True A patient presents to the physician's office with pinpoint hemorrhages on the skin. The patient is most likely between the ages of _____ years. 4 and 7 Most carbon dioxide is transported in the bloodstream as bicarbonate ion. Which characteristic is indicative of hemolytic anemia? Jaundice Pernicious anemia is caused by a lack of intrinsic factor. Which causes vasoconstriction? Norepinephrine What laboratory finding is usually found in aplastic anemia? Pancytopenia Disseminated intravascular coagulation may be treated with heparin therapy to inhibit clotting factor consumption. The anemia resulting from a deficiency of either vitamin B12 (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. Ture or False True Which vessel normally demonstrates the most rapid blood flow?
