Question 1 of 5
Increase serum iron:-decrease IBC a feature of:
Correct Answer: B
Rationale: Step-by-step rationale: 1. Sideroblastic anemia results in defective heme synthesis, leading to iron accumulation in the mitochondria. 2. This excess iron saturation decreases the Iron Binding Capacity (IBC) in the serum. 3. Therefore, in sideroblastic anemia, increasing serum iron is associated with a decrease in IBC. Summary of other choices: A: Hookworm infestation causes iron deficiency anemia with increased IBC. C: Alcoholic liver disease can lead to iron overload, not a decrease in IBC. D: Thalassemia major is associated with increased IBC due to ineffective erythropoiesis.
Question 2 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 3 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 4 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.
Question 5 of 5
A nurse is caring for a patient who has been diagnosed with leukemia. The nurse's most recent assessment reveals the presence of ecchymoses on the patient's sacral area and petechiae in her forearms. In addition to informing the patient's primary care provider, the nurse should perform what action?
Correct Answer: B
Rationale: Rationale: 1. Ecchymoses and petechiae indicate potential thrombocytopenia in leukemia. 2. Checking platelet levels will confirm if thrombocytopenia is present. 3. Low platelet levels increase bleeding risk, warranting intervention. 4. Initiating VTE prevention, isolation, or ambulation are not directly related to managing thrombocytopenia in leukemia. Summary: - A: VTE measures are not indicated with the given symptoms. - C: Protective isolation is unnecessary for thrombocytopenia. - D: Ambulation does not directly address thrombocytopenia.
