Anatomy of Hematologic System Questions
Question 1 of 5
Half life of plat. Is:
Correct Answer: B
Rationale: The correct answer is B: 3-4 days. The half-life of a substance is the time it takes for half of the original amount to decay. In this case, since the half-life of platinum is 3-4 days, it means that after 3-4 days, half of the initial amount of platinum will have decayed. This answer is correct because it accurately represents the time frame for platinum decay. The other choices are incorrect because they do not correspond to the known half-life of platinum. Choice A (1-2 days), C (5-6 days), and D (7-8 days) are outside the typical half-life range for platinum, making them incorrect options.
Question 2 of 5
A 35-year-old male is admitted to the hospital complaining of severe headaches, vomiting, and testicular pain. His blood work shows reduced numbers of platelets, leukocytes, and erythrocytes, with a high proportion of immature cells. The nurse caring for this patient suspects a diagnosis of what?
Correct Answer: D
Rationale: The correct answer is D: ALL (Acute Lymphoblastic Leukemia). In this scenario, the patient presents with symptoms of headaches, vomiting, testicular pain, and abnormal blood work showing reduced platelets, leukocytes, and erythrocytes with a high proportion of immature cells. These findings are characteristic of ALL, a type of leukemia that primarily affects lymphoid cells. The combination of symptoms and blood work results suggests a rapid and aggressive proliferation of immature lymphoid cells, leading to bone marrow failure and symptoms such as anemia, thrombocytopenia, and leukopenia. AML (choice A) primarily affects myeloid cells, not lymphoid cells. CML (choice B) typically presents with elevated leukocyte count and presence of the Philadelphia chromosome. MDS (choice C) is a group of disorders characterized by ineffective hematopoiesis leading to cytopenias, but does not typically present with the rapid onset of symptoms seen in this case
Question 3 of 5
A patient with non-Hodgkin's lymphoma is receiving information from the oncology nurse. The patient asks the nurse why she should stop drinking and smoking and stay out of the sun. What would be the nurse's best response?
Correct Answer: D
Rationale: The correct answer is D because reducing factors that increase the risk of second cancers is crucial for a patient with non-Hodgkin's lymphoma due to the potential for developing secondary cancers. Alcohol, smoking, and sun exposure are known risk factors for various cancers, including secondary cancers. By avoiding these behaviors, the patient can decrease the likelihood of developing another cancer. Choice A is incorrect because while health promotion activities are beneficial, the specific reason for a patient with non-Hodgkin's lymphoma to stop drinking, smoking, and avoiding sun exposure is to reduce the risk of second cancers, not just for general health. Choice B is incorrect because it uses fear tactics and does not provide a clear rationale for why the patient should make these lifestyle changes. Choice C is incorrect because it lacks a specific explanation for the importance of avoiding alcohol, smoking, and sun exposure in relation to reducing the risk of second cancers.
Question 4 of 5
A 60-year-old patient with chronic myeloid leukemia will be treated in the home setting and the nurse is preparing appropriate health education. What topic should the nurse emphasize?
Correct Answer: A
Rationale: The correct answer is A: The importance of adhering to the prescribed drug regimen. This is crucial in managing chronic myeloid leukemia effectively. Medication adherence is essential to control the disease and prevent complications. Skipping doses can lead to treatment failure or drug resistance. B: While vaccinations are important, they are not the top priority in managing chronic myeloid leukemia. C: Daily physical activity is beneficial for overall health but is not the primary concern in this case. D: Avoiding shellfish and raw foods is not a key aspect of managing chronic myeloid leukemia.
Question 5 of 5
After receiving a diagnosis of acute lymphocytic leukemia, a patient is visibly distraught, stating, 'I have no idea where to go from here.' How should the nurse prepare to meet this patient's psychosocial needs?
Correct Answer: C
Rationale: Rationale for Choice C (Correct Answer): Assessing the patient's specific needs for education and support is crucial in meeting the psychosocial needs of a patient diagnosed with acute lymphocytic leukemia. By understanding the patient's informational and emotional needs, the nurse can provide tailored support and resources, enhancing the patient's coping abilities and overall well-being. This approach fosters a therapeutic relationship and promotes patient-centered care. Summary of Other Choices: A: Assessing the patient's previous experience with the health care system is important but may not directly address the immediate psychosocial needs related to the new diagnosis. B: Reassuring the patient about treatment success is premature and may invalidate the patient's feelings of distress and uncertainty. D: Identifying the patient's plan of medical care is essential but focuses more on the medical aspect rather than the psychosocial aspect of care.
