PATHOLOGY TEST 2 FINAL EXAM QUESTIONS AND ANSWERS ALL CORRECT.

PATHOLOGY TEST 2 FINAL EXAM QUESTIONS AND ANSWERS ALL CORRECT.  Question 1 0.125 out of 0.125 points Which vessel normally demonstrates the most rapid blood flow? Selected Answer: c. The vena cava Correct Answer: c. The vena cava Response Feedback: The vena cava has the most rapid rate of flow. Arterioles don’t offer the most rapid blood flow. Capillaries are composed of a single thickness of endothelial cells attached to a protein network called the basement membrane and don’t offer the most rapid blood flow. A venule begins where the arteriole ends and doesn’t offer the most rapid blood flow.  Question 2 0.125 out of 0.125 points Pernicious anemia is caused by a lack of Selected Answer: b. intrinsic factor. Correct Answer: b. intrinsic factor. Response Feedback: The fundamental defect causing pernicious anemia is the lack of intrinsic factor. Without it, vitamin B12 cannot be absorbed. Iron deficiency does not lead to pernicious anemia. Rather, it is the most common cause of anemia and is the result of unavailability of iron for hemoglobin synthesis. Pernicious anemia and folate deficiency are similar in etiology. Both are caused by a disruption in DNA synthesis of blast cells in bone marrow. Erythropoietin is necessary for the production of red cells.  Question 3 0.125 out of 0.125 points 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. Downloaded by charity nimo () lOMoARcPSD| PATHOLOGY TEST 2 FINAL EXAM QUESTIONS AND ANSWERS ALL CORRECT. Selected Answer: a. True Correct Answer: a. True Response Feedback: Compression of the spinal cord is one of the two most serious oncology emergencies associated with non-Hodgkin lymphoma.  Question 4 0 out of 0.125 points The most common primary immune deficiency that affects only B cells is Selected Answer: d. Bruton agammaglobulinemia. Correct Answer: c. selective IgA. Response Feedback: The most common B-cell primary immunodeficiency disorder is selective IgA deficiency. This disorder affects 1:2000 persons. DiGeorge is a T-cell primary immune deficiency. Bruton agammaglobulinemia is not the most common primary immune deficiency affecting B cells; frequency of disease is 1:250,000 males. Females are carriers. Wiskott–Aldrich affects both T cells and B cells.  Question 5 0.125 out of 0.125 points The effects of histamine release include Selected Answer: c. increased vascular permeability. Correct Answer: c. increased vascular permeability. Response Feedback: Histamine release leads to increased vascular permeability, which fosters fluid movement out of capillaries and into tissues leading to the edema common in type I hypersensitivity. Histamine leads to bronchoconstriction, increased gut permeability, and vasodilation (not vasoconstriction).  Question 6 0.125 out of 0.125 points Downloaded by charity nimo () lOMoARcPSD| PATHOLOGY TEST 2 FINAL EXAM QUESTIONS AND ANSWERS ALL CORRECT. Risk factors for atherosclerosis include Selected Answer: d. hyperlipidemia. Correct Answer: d. hyperlipidemia. Response Feedback: Hyperlipidemia is a modifiable risk factor associated with atherosclerosis. Men have a higher incidence of atherosclerosis earlier in life than women. A high-protein diet is not associated with atherosclerosis. Dietary fats do play a role as a modifiable risk factor. A low-fiber diet is not a risk factor for atherosclerosis.  Question 7 0.125 out of 0.125 points Patients with immunodeficiency disorders are usually first identified because they Selected Answer: c. develop recurrent infections. Correct Answer: c. develop recurrent infections. Response Feedback: The first clinical indicators of immunodeficiency disorders are the signs and symptoms of infection, and the disorders are often first suspected when an individual has severe recurrent, unusual, or unmanageable infections. High fevers can occur in patients who have an intact immune system. Because of the immune deficiency, patients with immunodeficiency disorders may not demonstrate expected WBC counts with infection. Infections in patients with immunodeficiency disorders can occur anywhere in the body.
