Of the following, the genetic syndrome MOST likely associated with increased risk of optic glioma is

Correct Answer: B

Rationale: The correct answer is B) neurofibromatosis. Neurofibromatosis, specifically type 1 (NF1), is a genetic syndrome associated with an increased risk of optic glioma, a type of tumor that occurs along the optic nerve. This condition commonly presents in childhood and can lead to vision problems if left untreated. Option A) Down syndrome is a genetic disorder caused by the presence of an extra chromosome 21. While individuals with Down syndrome may have an increased risk of certain health conditions, optic glioma is not typically associated with this syndrome. Option C) Monosomy refers to a genetic condition where a cell has only one copy of a particular chromosome instead of the usual two. This is not specifically linked to an increased risk of optic glioma. Option D) Bloom's syndrome is a rare genetic disorder characterized by short stature, sun sensitivity, and an increased risk of cancer. While some individuals with Bloom's syndrome may develop tumors, optic glioma is not a common feature of this condition. Educational Context: Pediatric nursing practice requires a thorough understanding of various genetic syndromes and their associated health risks. Recognizing the signs and symptoms of conditions like neurofibromatosis is crucial for early detection and intervention to prevent potential complications such as optic glioma. By understanding the distinctive features of different genetic syndromes, nurses can provide comprehensive care and support to pediatric patients and their families.

Correct Answer: D

Rationale: Tumor lysis syndrome (TLS) is a potentially life-threatening complication that can occur during the treatment of pediatric malignancies. It is characterized by metabolic disturbances such as hyperuricemia, hyperkalemia, hyperphosphatemia, and hypocalcemia resulting from the rapid breakdown of tumor cells. In this scenario, Burkitt lymphoma is more likely to manifest TLS compared to the other malignancies listed. Burkitt lymphoma is a highly proliferative B-cell non-Hodgkin lymphoma that is very sensitive to chemotherapy. The rapid cell turnover in Burkitt lymphoma leads to a higher risk of TLS due to the release of intracellular contents into the bloodstream during treatment initiation. Acute myelogenous leukemia (AML) is associated with a high tumor burden but does not typically cause the same degree of rapid cell lysis seen in Burkitt lymphoma. Nephroblastoma (Wilms tumor) and neuroblastoma are pediatric solid tumors that, although they can be large, are less likely to lead to TLS compared to highly proliferative hematologic malignancies like Burkitt lymphoma. Educationally, understanding the risk factors and manifestations of TLS in pediatric oncology is crucial for nurses caring for children with cancer. Recognizing the signs and symptoms of TLS, monitoring laboratory values closely, and implementing preventive measures are essential in the management of pediatric patients at risk for this serious complication.

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.
