NUR 555 -quiz 3 : Questions and answers latest update (SNHU)

What does the student learn about erythrocytes? Select one. Question options: a) 20 to 30 b) 60 to 90 c) 200 to 240 d) 100 to 120 Hide question 1 feedback Feedback Because it cannot undergo mitotic division, the erythrocyte has a limited life span of up days. ion 2 1.2 / 1.2 points Shortened erythrocyte life span, ineffective bone marrow response to erythropoietin, and altered iron metabolism describe the pathophysiologic characteristics of which type of anemia? Select one. Question options: a) Aplastic b) Anemia of chronic disease c) Iron deficiency d) Sideroblastic Hide question 2 feedback Feedback Anemia of chronic disease specifically results from a combination of (1) decreased eryth suppressed production of erythropoietin, (3) ineffective bone marrow erythroid progenit erythropoietin, and (4) altered iron metabolism and iron sequestration in macrophages. ion 3 1.2 / 1.2 points The healthcare professional explains to a student that glucose 6-phosphate dehydrogenase (G6PD) deficiency is what type of inherited disorder? Select one. Question options: a) X-linked dominant b) Autosomal dominant c) X-linked recessive d) Autosomal recessive Hide question 3 feedback Feedback G6PD deficiency is an inherited, X-linked recessive disorder. ion 4 1.2 / 1.2 points A patient is 8 hours postoperative after a long orthopedic procedure. The student asks why this patient is at particular risk of developing a thromboembolism. What response by the healthcare professional is best? Select one. Question options: a) Endothelial damage occurs and repair is slowed by postoperative pain. b) Atherosclerotic build up causes turbulent blood flow leading to clots. c) Patients tend to have venous stasis from orthopedic operations. d) Anesthetic agents often cause an immune response against clotting factors. Hide question 4 feedback Feedback Thromboembolic events are caused by some component of Virchow triad: endothelial inj flow, and hypercoagulability of the blood. Long operative procedures such as orthopedic stasis. Anesthetic agents are not implicated. Endothelial repair is not appreciably hinder pain. Atherosclerotic buildup can lead to endothelial injury but that is not specific to this ion 5 1.2 / 1.2 points A hospitalized patient's lab work is as follows: WBC 2000, bands 14.8%, and segmented neutrophils 5. The healthcare professional calculates the patient's absolute neutrophil count (ANC). What action does the professional take next? Select one. Question options: a) Implements protocols to prevent life-threatening infections b) Encourages the patient to limit any visitors for the present time c) Does nothing; this is a normal ANC for the white cell count d) Holds the patient's medications until the ANC returns to normal Hide question 5 feedback Feedback The ANC is calculated by multiplying the white blood cell count by the sum of the bands neutrophils. This patient's ANC is 396, placing him or her at extremely high risk of deve threatening infection. Visitors may need to be limited but that will not protect the patien infection. The patient's medications would not all be held because of this finding. ion 6 1.2 / 1.2 points A patient has been diagnosed with acute lymphocytic leukemia (ALL) and asks the healthcare professional to describe it. What description by the professional is most accurate? Select one. Question options: a) ALL is a progressive neoplasm defined by the presence of greater than 30% lymph marrow or blood. b) The translocation of genetic material from genes 9 and 22 create an abnormal, fus as BCR-ABL. c) B cells fail to mature into plasma cells that synthesize immunoglobulins. d) In ALL, immature blasts cells replace normal myelocytic cells, megakaryocytes, an Hide question 6 feedback Feedback ALL is a progressive neoplasm defined by the presence of greater than 30% lymphoblast or blood. Leukemia is a malignant disorder of leukocytes and does not involve immunogl gene has been identified in chronic myelogenous leukemia, not ALL. ion 7 ion 8 ion 9 0 / 1.2 points A patient is admitted to the hospital with multiple myeloma (MM). Which diagnostic test should the healthcare professional assess as the priority? Select one. Question options: a) Serum potassium level b) Bone scan or limb x-rays c) Bone marrow biopsy d) Serum calcium level Hide question 7 feedback Feedback Many clinical manifestations of MM are due to hypercalcemia. Since calcium can affect priority diagnostic test is serum calcium levels. Bone destruction does occur in MM, but bones is not a higher priority than the calcium. The patient already has been diagnosed marrow biopsy may not be needed at this time. Potassium and other electrolytes will be priority.
