Which type of leukemia has been MOST likely developed in a 2-year-old child with Down syndrome in the neonatal period?

Correct Answer: D

Rationale: In this scenario, the correct answer is D) AML M6. Acute Myeloid Leukemia (AML) is the most likely type of leukemia to develop in a 2-year-old child with Down syndrome in the neonatal period. Children with Down syndrome have a higher risk of developing AML compared to other types of leukemia. AML M6 specifically refers to acute erythroleukemia, which is characterized by the presence of both myeloid and erythroid blasts in the bone marrow. Option A, ALL (Acute Lymphoblastic Leukemia), is less likely in this case as Down syndrome is not strongly associated with ALL. Option B, CML (Chronic Myeloid Leukemia), is a chronic leukemia that typically occurs in adults, making it less likely in a 2-year-old child. Option C, AML M1, is a subtype of AML but is less common in children with Down syndrome compared to AML M6. Educationally, understanding the association between Down syndrome and specific types of leukemia is crucial for nursing students caring for pediatric patients. This knowledge helps in early identification, appropriate treatment, and better outcomes for children with Down syndrome who may develop leukemia. It also highlights the importance of personalized care based on both the patient's age and underlying conditions.

Correct Answer: B

Rationale: In understanding the development of hemangiomas in infants, it is important to recognize that the most common risk factor is being a female infant. This is because hemangiomas are more prevalent in girls compared to boys. This gender predisposition is a key factor in the pathogenesis of hemangiomas. Regarding the other options: A) Being a male infant is not a risk factor for the development of hemangiomas, as mentioned earlier, they are more common in female infants. C) Being an infant of a diabetic mother is not a significant risk factor for hemangioma development. While maternal diabetes can have implications for the baby, it is not directly linked to hemangioma development. D) Being delivered by cesarean section is also not a risk factor for hemangioma development. The mode of delivery does not impact the likelihood of developing a hemangioma. In an educational context, understanding the risk factors associated with hemangiomas is crucial for nurses and healthcare providers working with pediatric patients. By knowing that being a female infant is the most common risk factor, healthcare professionals can better assess, monitor, and provide care for infants who may develop hemangiomas. This knowledge can also guide discussions with parents regarding the condition and its management.

Correct Answer: C

Rationale: In the context of pediatric oncology, Acute Lymphoblastic Leukemia (ALL) is a common malignancy. Understanding the factors that influence outcomes in children with ALL is crucial for nurses caring for these patients. Option C, hyperdiploidy chromosomal abnormality, is the correct answer. This abnormality is associated with a favorable prognosis in children with ALL, contrary to the other options. Option A suggests that age younger than 1 year and older than 10 years is associated with a poor outcome in ALL. Younger age is actually a favorable prognostic factor in pediatric ALL. Option B, T-cell immunophenotype, is often associated with a poorer prognosis compared to B-cell ALL. Option D, an initial leukocyte count of >50,000, is considered a high-risk feature in ALL and is associated with a poorer prognosis. Educationally, understanding prognostic factors in pediatric ALL is essential for nurses to provide comprehensive care, anticipate complications, and support families. By knowing which factors indicate a poor outcome, nurses can intervene promptly and advocate for appropriate treatment strategies.

Correct Answer: A

Rationale: The correct answer is A) medulloblastoma. Extraneural metastasis from primary brain tumors is most commonly seen in medulloblastoma due to its aggressive nature and propensity for spreading to other parts of the body. Medulloblastoma is a highly malignant embryonal tumor that primarily affects children. It tends to metastasize through the cerebrospinal fluid to the spinal cord, bone, and other organs. Option B) primitive neuroectodermal tumor (PNET) is incorrect because while it is also an aggressive brain tumor, extraneural metastasis is more commonly associated with medulloblastoma. Option C) ependymoma is less likely to metastasize outside the central nervous system compared to medulloblastoma. Option D) malignant glioma, while a common primary brain tumor in adults, is less likely to metastasize outside the brain as compared to medulloblastoma in children. Understanding the patterns of metastasis in different types of brain tumors is crucial for nurses and healthcare professionals caring for pediatric patients with these conditions. It informs treatment decisions, prognosis discussions, and follow-up care planning.

Correct Answer: D

Rationale: In pediatric oncology, understanding the responsiveness of different solid tumors to radiotherapy is crucial for determining effective treatment strategies. In this scenario, the correct answer is D) osteosarcoma. Osteosarcoma is the least responsive tumor to radiotherapy among the options provided. Osteosarcoma is a type of bone cancer that is relatively radioresistant, meaning it does not respond as well to radiotherapy compared to other pediatric solid tumors. This is due to the dense and mineralized nature of bone tissue, which can limit the effectiveness of radiation in targeting and destroying cancer cells within the bone. On the other hand, options A, B, and C (rhabdomyosarcoma, neuroblastoma, and nephroblastoma) are more responsive to radiotherapy than osteosarcoma. Rhabdomyosarcoma is a soft tissue tumor that typically responds well to radiotherapy. Neuroblastoma and nephroblastoma (Wilms tumor) are also known to be sensitive to radiation therapy, with high rates of response and successful outcomes when treated with this modality. For nursing students preparing for the ATI Nursing Proctored Pediatric Test, understanding the varying responses of pediatric solid tumors to different treatment modalities, including radiotherapy, is essential. This knowledge informs clinical decision-making and helps ensure appropriate and effective care for pediatric oncology patients.
