Which chromosomal abnormality is often characteristic of infantile ALL?

Correct Answer: A

Rationale: In pediatric nursing, understanding chromosomal abnormalities associated with different conditions is crucial for accurate diagnosis and treatment. In the case of infantile Acute Lymphoblastic Leukemia (ALL), the chromosomal abnormality t(4;11) is often characteristic. This translocation results in the fusion of the MLL gene on chromosome 11 with various partner genes on chromosome 4, leading to the overexpression of MLL fusion proteins that play a role in leukemogenesis in infants. Option A, t(4;11), is the correct answer because it is specifically linked to infantile ALL. This translocation is a common genetic feature in this age group and is associated with a poorer prognosis compared to other subtypes of ALL. Options B, C, and D are incorrect for infantile ALL. Option B, t(12;21), is typically associated with a better prognosis in childhood ALL. Option C, t(9;22), is characteristic of Chronic Myeloid Leukemia (CML) and not infantile ALL. Option D, t(1;19), is associated with a subtype of pre-B cell ALL. Educationally, understanding the genetic basis of diseases like ALL enhances nurses' ability to provide comprehensive care, including recognizing potential complications and collaborating with the healthcare team to develop individualized treatment plans. This knowledge also informs patient and family education, helping them better understand the condition and its implications. Consequently, being well-versed in chromosomal abnormalities in pediatric oncology is essential for pediatric nurses to deliver high-quality care to their young patients.

Correct Answer: D

Rationale: In the treatment of high-risk neuroblastoma in children, current protocols involve a multimodal approach that includes surgery, intensive chemotherapy, and radiation therapy. Allogeneic bone marrow transplantation is not a standard part of the treatment regimen for high-risk neuroblastoma in children. The correct answer, D, is not a part of the standard treatment because allogeneic bone marrow transplantation has not demonstrated significant efficacy in improving outcomes for children with high-risk neuroblastoma. While bone marrow transplantation may be considered in certain cases or in research settings, it is not a routine part of the established treatment guidelines for this condition. Surgery is often used to remove the primary tumor and any metastatic sites, while intensive chemotherapy and radiation therapy are aimed at eradicating remaining cancer cells. These modalities have been shown to improve survival rates in children with high-risk neuroblastoma. In an educational context, understanding the rationale behind each treatment modality is crucial for healthcare providers caring for pediatric oncology patients. It is important to be aware of the current evidence-based practices to provide the best possible care and outcomes for children with high-risk neuroblastoma. By knowing which treatments are standard and which are not, healthcare professionals can make informed decisions and advocate for the most effective therapies for their young patients.

Correct Answer: D

Rationale: In pediatric oncology, understanding prognostic factors in Wilms tumor is crucial for providing optimal care. In this context, the correct answer, option D, "young age at diagnosis," is the exception among the adverse prognostic factors. Children diagnosed at a young age with Wilms tumor typically have a more favorable prognosis compared to older children. This is due to the fact that younger children tend to respond better to treatment and have a higher survival rate. Options A, B, and C are adverse prognostic factors in children with Wilms tumor. Large tumors (option A) can indicate a more advanced stage of the disease, making treatment more challenging. Anaplastic histology (option B) is associated with a more aggressive form of Wilms tumor, leading to a poorer prognosis. Loss of heterozygosity at chromosome 1p and 16q (option C) is a genetic abnormality that can also indicate a higher risk of disease progression and worse outcomes. Educationally, recognizing these prognostic factors is essential for healthcare professionals caring for pediatric oncology patients. Understanding these factors helps in treatment planning, monitoring patient progress, and providing families with accurate prognostic information. It also underscores the importance of personalized and evidence-based care in pediatric oncology practice.

Correct Answer: D

Rationale: In pediatric nursing, it is crucial to understand the implications of various conditions on both the surface and internal organs of young patients. In this case, the correct answer is D) liver. Hemangiomas are benign tumors composed of blood vessels. While cutaneous hemangiomas are common in infants, they can also affect internal organs. The liver is the most common site of visceral involvement by hemangiomas in infants. Option A) brain is less common for hemangioma involvement compared to the liver in infants. Option B) heart is also less frequently affected by hemangiomas than the liver. Option C) lung involvement by hemangiomas is rare in infants compared to hepatic involvement. Understanding the common sites of visceral involvement by hemangiomas is essential for pediatric nurses to monitor and provide appropriate care for infants with these conditions. Pediatric nurses must be knowledgeable about the potential complications and manifestations of hemangiomas in infants to ensure early detection and intervention. Recognizing the most common sites of visceral involvement, such as the liver, enables nurses to collaborate effectively with healthcare providers in managing these cases and promoting optimal outcomes for pediatric patients.

Correct Answer: E

Rationale: In this case, the correct answer is "E) easily bleeds." This option does not raise suspicion of melanoma because bleeding is not typically a characteristic feature of melanoma. Melanomas usually present with specific signs that help differentiate them from benign nevi. Option A, an enlarging nevus, is concerning for melanoma as melanomas often grow in size. Option B, changing colors, is also a red flag as melanomas can exhibit various colors within the lesion. Option C, irregular margins, is another classic sign of melanoma as benign nevi typically have smooth, well-defined borders. Educationally, it is crucial for nurses to understand the key characteristics of melanoma to differentiate it from benign skin lesions. Assessing nevi in pediatric patients requires a keen eye for changes that may indicate malignancy. By knowing these distinguishing features, nurses can provide appropriate guidance and referrals for further evaluation to ensure early detection and treatment if necessary.
