In Langerhans cell histiocytosis (LCH), all the following manifestations are at high risk of mortality in patients EXCEPT

Correct Answer: C

Rationale: In Langerhans cell histiocytosis (LCH), manifestations in the lung are not typically associated with high mortality risk. The correct answer is C) lung. The lung involvement in LCH is common but usually does not lead to mortality. On the other hand, liver involvement (option A), splenic involvement (option B), and hematopoietic system involvement (option D) in LCH can lead to severe complications and increase the risk of mortality in patients. Educationally, understanding the specific organ involvement and associated risks in LCH is crucial for healthcare providers managing pediatric patients with this condition. This knowledge helps in early recognition of potentially life-threatening complications and enables prompt intervention to improve outcomes. It also highlights the importance of a multidisciplinary approach in the care of children with LCH, involving specialists from various fields to address the diverse manifestations of the disease.

Correct Answer: D

Rationale: The correct answer is D) biopsy of the mass. In the case of a suspected Wilms tumor in a pediatric patient, obtaining a biopsy of the mass is least likely to be performed as the initial diagnostic investigation. This is because biopsy carries the risk of seeding tumor cells and potentially altering the staging and prognosis of the tumor. Option A) plain abdominal radiography may be used to assess for the presence of a mass or calcifications. Option B) and C) suggest performing CT scans of the abdomen and chest, respectively, which are commonly used to evaluate the extent of the tumor and assess for metastasis. In an educational context, understanding the appropriate diagnostic approach in suspected cases of Wilms tumor is crucial for healthcare providers managing pediatric oncology cases. By recognizing the importance of avoiding biopsy as the initial step, providers can ensure optimal patient care and outcomes by following evidence-based diagnostic guidelines.

Correct Answer: D

Rationale: Kasabach-Merritt syndrome is a rare condition characterized by thrombocytopenia, microangiopathic hemolytic anemia, and coagulopathy. The correct answer is D) association with infantile hemangiomas. This is because Kasabach-Merritt syndrome is not directly associated with infantile hemangiomas; rather, it is a severe complication that can occur alongside large vascular tumors like kaposiform hemangioendothelioma and tufted angioma. Option A) thrombocytopenia is a characteristic feature of Kasabach-Merritt syndrome, as the vascular tumor can lead to platelet consumption and subsequent low platelet counts. Option B) microangiopathic hemolytic anemia is also seen in this syndrome due to the destruction of red blood cells as they pass through the abnormal blood vessels. Option C) coagulopathy is a common manifestation in Kasabach-Merritt syndrome, as the abnormal blood vessels can lead to abnormal clotting factors and bleeding tendencies. In an educational context, understanding the features of Kasabach-Merritt syndrome is crucial for healthcare providers, especially those working in pediatrics. Recognizing these clinical signs early can lead to prompt diagnosis and appropriate management, which often involves a multidisciplinary approach. This question helps reinforce the key characteristics of Kasabach-Merritt syndrome and highlights the importance of considering this diagnosis in pediatric patients presenting with vascular tumors and associated complications.

Correct Answer: A

Rationale: The correct answer is A) Let's talk about preventing and managing your asthma on a daily basis at home. This response is the best because it acknowledges the adolescent's concerns, shows empathy, and shifts the focus to empowering the patient to take control of their asthma management. By discussing prevention strategies and daily management techniques, the nurse can help the patient feel more confident in managing their condition outside of the hospital setting. Option B is incorrect because it bypasses directly addressing the adolescent's feelings and needs by immediately involving the parents. While parental involvement is essential, the immediate need is to address the adolescent's emotional state and empower them. Option C is incorrect because it does not address the underlying issue of helping the patient manage their asthma effectively at home. Prolonged hospital stays are not always the best solution and can disrupt the patient's daily life and routine. In an educational context, it is crucial for pediatric nurses to recognize and address the emotional well-being of adolescent patients with chronic conditions like asthma. By providing support, education, and tools for self-management, nurses can help adolescents feel more in control of their health and reduce the likelihood of hospital readmissions. Empowering patients to manage their conditions independently is key to improving their quality of life and health outcomes.

Correct Answer: D

Rationale: The correct answer is D) speaks inhibition word 'no.' At 10 months, children typically develop receptive language skills, understanding simple commands and pointing to objects or saying their first words. However, the ability to use inhibition words like "no" usually emerges later, around 18-24 months. Option A is incorrect because saying "mama" or "dada" is a common milestone around 6-9 months. Option B is incorrect as following a one-step command without gesture is expected around 12 months. Option C is incorrect as pointing to objects or saying a first word is also a typical milestone by 10 months. In an educational context, understanding typical developmental milestones in language acquisition is crucial for educators and healthcare professionals working with children. Recognizing these milestones can help identify potential developmental delays early, allowing for timely intervention and support. By understanding what is developmentally appropriate at different ages, professionals can provide more targeted and effective care and support for children's language development.
