ATI Hematologic System Test Questions
Question 1 of 5
Thrombocytopenia is absent in:
Correct Answer: C
Rationale: Thrombocytopenia is absent in Henoch Schonlein purpura because it is primarily a vasculitis affecting small blood vessels, not directly causing platelet destruction. Thrombocytopenia is present in DIC due to widespread coagulation activation. Wiskott Aldrich syndrome and myelosclerosis both involve platelet dysfunction or decreased production, leading to thrombocytopenia.
Question 2 of 5
C6PD reflect false normal report in:
Correct Answer: D
Rationale: The correct answer is D, shortly after hemolysis, because G6PD deficiency leads to a false-normal result due to the presence of reticulocytes in the blood following hemolysis. This is because reticulocytes have normal enzyme activity, masking the underlying deficiency. Iron deficiency anemia (A), hypoplastic anemia (B), and hairy cell leukemia (C) do not involve the same mechanism of false-normal reports in C6PD deficiency as seen in hemolysis.
Question 3 of 5
An oncology nurse is providing health education for a patient who has recently been diagnosed with leukemia. What should the nurse explain about commonalities between all of the different subtypes of leukemia?
Correct Answer: A
Rationale: The correct answer is A because all subtypes of leukemia involve unregulated proliferation of white blood cells (WBC). Leukemia is a type of cancer that starts in the blood-forming tissues, leading to the production of abnormal WBCs in the bone marrow. This uncontrolled growth of WBCs interferes with the production of normal blood cells. Choice B is incorrect because leukemia does not involve unregulated proliferation of red blood cells, but rather white blood cells. It also does not necessarily result in decreased bone marrow function as stated in the choice. Choice C is incorrect because while some subtypes of leukemia may result in a decrease in the production of normal white blood cells, the primary issue is the unregulated proliferation of abnormal WBCs. Choice D is incorrect because leukemia is not specifically related to cancer development in the lymphatic system. Leukemia primarily affects the bone marrow and blood.
Question 4 of 5
A 77-year-old male is admitted to a unit with a suspected diagnosis of acute myeloid leukemia (AML). When planning this patient's care, the nurse should be aware of what epidemiologic fact?
Correct Answer: C
Rationale: The correct answer is C: Five-year survival for patients over 75 years old is less than 2%. This is because older age is a significant risk factor for poorer outcomes in acute myeloid leukemia (AML) due to factors such as frailty, comorbidities, and reduced tolerance to aggressive treatments. Older adults are less likely to tolerate intensive chemotherapy and have lower overall survival rates compared to younger patients. Choice A is incorrect because early diagnosis alone does not guarantee good outcomes in AML, especially in older adults. Choice B is incorrect because the five-year survival rate for older adults with AML is much lower than 50%. Choice D is incorrect because while pre-illness health may influence survival rates, age is a more significant factor in predicting outcomes in older patients with AML.
Question 5 of 5
A nurse is caring for a patient with Hodgkin lymphoma at the oncology clinic. The nurse should be aware of what main goal of care?
Correct Answer: A
Rationale: The correct answer is A: Cure of the disease. In Hodgkin lymphoma, the main goal of care is to achieve a cure whenever possible. This is because Hodgkin lymphoma is a potentially curable cancer with appropriate treatment. Curative intent focuses on eradicating the cancer completely, leading to long-term remission or cure. Enhancing quality of life (B) is important but not the main goal in Hodgkin lymphoma as the primary aim is to eliminate the disease. Controlling symptoms (C) is important for comfort but not the main goal in curable cases. Palliation (D) is more relevant in advanced or incurable cases, not the main goal in Hodgkin lymphoma.
