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 primarily involves vasculitis, not platelet destruction or consumption. In DIC (A), there is widespread activation of coagulation leading to thrombocytopenia. Wiskott Aldrich syndrome (B) is characterized by low platelet counts due to defective platelet function. Myelosclerosis (D) is a bone marrow disorder causing decreased platelet production, leading to thrombocytopenia.
Question 2 of 5
C6PD reflect false normal report in:
Correct Answer: D
Rationale: The correct answer is D because individuals with G6PD deficiency can have normal enzyme levels shortly after a hemolytic episode due to the body replenishing the enzyme. Choice A, iron deficiency anemia, is unrelated to G6PD deficiency. Choice B, hypoplastic anemia, does not affect enzyme levels. Choice C, hairy cell leukemia, is not typically associated with false-normal G6PD levels. Therefore, the correct answer is D as it reflects the transient nature of G6PD levels post-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: The different leukemias all involve unregulated proliferation of WBC. Leukemia is a type of cancer that affects the blood and bone marrow, leading to the uncontrolled growth of white blood cells. This abnormal proliferation of white blood cells is a common feature across all subtypes of leukemia. Explanation: 1. Leukemia is a cancer of the blood and bone marrow. 2. In leukemia, there is uncontrolled proliferation of white blood cells. 3. Different subtypes of leukemia may have specific characteristics, but they all involve the abnormal growth of white blood cells. Summary: Choice B is incorrect because leukemias do not involve unregulated proliferation of red blood cells. Choice C is incorrect because leukemias do not always result in a decrease in white blood cell production. Choice D is incorrect because leukemia is not specifically related to the lymphatic system; it affects the blood and bone marrow.
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 negative prognostic factor in acute myeloid leukemia (AML). As individuals age, their overall health and ability to tolerate aggressive treatments decline, leading to poorer outcomes. The survival rate of less than 2% for patients over 75 years old reflects the challenges of treating AML in this age group. Choice A is incorrect because early diagnosis does not necessarily guarantee good outcomes in AML, especially in older adults where other factors play a significant role. Choice B is incorrect as the five-year survival rate of 50% does not apply to older adults with AML. Choice D is incorrect as survival rates in AML are influenced by various factors beyond just the patient's pre-illness health status.
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. The main goal of care for a patient with Hodgkin lymphoma is to achieve a cure whenever possible. This is because Hodgkin lymphoma is a potentially curable cancer with appropriate treatment. Achieving a cure means eradicating the cancer cells completely and preventing its recurrence in the future. This is the most desirable outcome for the patient's long-term health and well-being. Incorrect choices: B: Enhancing quality of life - While improving the patient's quality of life is important, the primary goal in treating Hodgkin lymphoma is to cure the disease. C: Controlling symptoms - Symptom management is important in providing comfort to the patient, but the main goal is to cure the disease. D: Palliation - Palliative care focuses on relieving symptoms and improving quality of life in patients with advanced or incurable diseases. For Hodgkin lymphoma, the main goal is to aim for a cure rather than palliation.
