Question 1 0.125 out of 0.125 points Patients who experience anemic episodes when exposed to certain drugs most likely have Selected Answer: c. glucose-6-phosphate dehydrogenase deficiency. Correct Answer: c. glucose-6-phosphate dehydrogenase deficiency. Response Feedback: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a RBC intracellular defect. Usually this anemia is first recognized during or after an infectious illness or exposure to certain drugs. Thalassemia does not carry a manifestation associated with pharmacologic agents. Spherocytosis is a hereditary anemia with manifestations of jaundice. Episodes of sickle cell anemia are associated with recurrent painful episodes related to organ dysfunction. Question 2 0.125 out of 0.125 points Renal insufficiency is a common complication of which disease? Selected Answer: c. Myelo ma Correct Answer: c. Myelo ma Response Feedback: Renal insufficiency is seen in approximately 50% of patients with plasma cell myeloma, because of hyperproteinemia, Bence Jones protein, hypercalcemia, and hyperuricemia. Chronic myeloid leukemia is manifested by splenomegaly. Chronic lymphoid leukemia is a disease that affects lymphoid tissues and bone marrow. Malignancy along lymphatic pathways is more typical of Hodgkin disease. Question 3 0.125 out of 0.125 points Blood flow throughout the periphery is regulated by Selected Answer: d. the autonomic nervous system.

Correct Answer: d. the autonomic nervous system. Response Feedback: Blood flow throughout the periphery is controlled by central mechanisms that are mediated by the autonomic nervous system, the venous and thoracic pumps, and intrinsic autoregulatory mechanisms. Cardiac output does not control peripheral blood flow. Velocity is the measure of distance traveled in a given interval. Hemodynamics is the principle that governs the quantity of blood passing by a given point at a certain period. Question 4 0.125 out of 0.125 points 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 Selected Answer: b. myelo ma. Correct Answer: b. myelo ma. Response Feedback: A diagnosis of plasma cell myeloma is confirmed by the presence of hypercalcemia, which can contribute to the compression fracture. Patients with leukemia diagnoses do not exhibit bone demineralization or elevated calcium levels. Lymphadenopathy is a more common manifestation of Hodgkin disease. Compression fractures can be the result of back trauma, but not in the presence of the other radiographic and laboratory results. Question 5 0.125 out of 0.125 points Pernicious anemia is caused by a lack of Selected Answer: a. intrinsic factor.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
