A 9-year-old boy with migratory polyarthritis, a new apical pansystolic murmur, fever, CRP+, and ASOT 500 units is diagnosed with rheumatic fever. What is his classification?

Correct Answer: C

Rationale: In this scenario, the correct classification for the 9-year-old boy with rheumatic fever is option C) Two major and two minor criteria. This classification is based on the Jones Criteria used to diagnose rheumatic fever. The presence of migratory polyarthritis and a new apical pansystolic murmur are considered major criteria, while fever, elevated CRP, and elevated ASOT levels are minor criteria. Option A) (Two major and one minor) is incorrect because the patient has two major criteria but also has two minor criteria, making it a more severe presentation. Option B) (Two major manifestations only) is incorrect as it overlooks the presence of minor criteria which are also important in the diagnosis of rheumatic fever. Option D) (Two minor manifestations only) is incorrect as the patient has both major and minor criteria present, requiring a more comprehensive classification. Educationally, understanding the Jones Criteria and how they are applied in diagnosing rheumatic fever is crucial for pediatric nurses. It helps in accurate assessment, diagnosis, and treatment of pediatric patients presenting with symptoms of rheumatic fever, ultimately leading to better patient outcomes.

Correct Answer: A

Rationale: In pediatric nursing, understanding the criteria for patent ductus arteriosus (PDA) is crucial for early identification and appropriate management. The correct answer is A) Wide pulse pressure. In PDA, the ductus arteriosus fails to close after birth, leading to a connection between the aorta and pulmonary artery. This results in a left-to-right shunt, causing an increase in blood flow to the lungs and subsequently widening the pulse pressure. Option B) Pan-systolic murmur is typically associated with mitral regurgitation, not PDA. Option C) Right apical impulse is indicative of right ventricular hypertrophy, commonly seen in conditions like pulmonary hypertension, not specific to PDA. Option D) Normal pulmonary venous markings would not be expected in PDA as increased blood flow to the lungs would likely cause pulmonary congestion. In an educational context, it is important for nursing students to grasp the clinical manifestations and assessment findings specific to PDA to provide safe and effective care to pediatric patients. Recognizing the key criteria such as wide pulse pressure can prompt timely interventions and prevent complications associated with untreated PDA. This knowledge underscores the significance of thorough assessment skills and understanding cardiac anomalies in pediatric nursing practice.

Correct Answer: A

Rationale: In pediatric nursing practice, it is crucial to understand the assessment findings associated with different pediatric respiratory conditions. In the case of a child with a large unilateral pneumothorax, the correct clinical examination finding would be decreased breath sound intensity, which is option A. 1. **Correct Answer (A):** Decreased breath sound intensity occurs in a pneumothorax due to the presence of air in the pleural space, which diminishes the transmission of sound through the lung tissue. This results in a decrease in breath sounds on the affected side during auscultation. 2. **Incorrect Options:** - **B) Increased tactile vocal fremitus:** Tactile vocal fremitus is usually decreased or absent in pneumothorax due to the interruption of sound transmission through the lung. - **C) Crepitations:** Crepitations are associated with conditions like pneumonia or pulmonary edema, not pneumothorax. - **D) Bronchial breathing:** Bronchial breathing is typically heard in conditions such as consolidation or atelectasis, not pneumothorax. 3. **Educational Context:** Understanding the clinical manifestations of pediatric respiratory conditions is vital for nurses caring for pediatric patients. Recognizing the unique assessment findings associated with pneumothorax in children helps in prompt identification and appropriate intervention, ensuring optimal patient outcomes. By comprehensively understanding the rationale behind the correct and incorrect options, pediatric nurses can enhance their clinical reasoning skills and provide high-quality care to pediatric patients with respiratory conditions.

Correct Answer: D

Rationale: Iron chelating agents are used for the treatment of chronic hemolytic anemia, which is characterized by the increased destruction of red blood cells leading to elevated levels of iron in the body. These agents help in removing the excess iron from the body, preventing iron overload which can lead to organ damage. Option A) Leukemia: Leukemia is a type of cancer affecting the blood and bone marrow. Iron chelating agents are not indicated for the treatment of leukemia as the primary treatment involves chemotherapy, radiation, and bone marrow transplantation. Option B) Lymphoma: Lymphoma is a cancer of the lymphatic system. Iron chelating agents are not used in the treatment of lymphoma as it is primarily managed with chemotherapy, radiation therapy, immunotherapy, or stem cell transplantation. Option C) Wilms tumor: Wilms tumor is a type of kidney cancer that primarily affects children. Iron chelating agents are not part of the standard treatment for Wilms tumor, which typically involves surgery, chemotherapy, and sometimes radiation therapy. Educationally, understanding the appropriate use of iron chelating agents in chronic hemolytic anemia is crucial for pediatric nurses. By knowing the indications for these agents, nurses can ensure proper administration, monitor for side effects, and educate patients and families on the importance of treatment compliance. This knowledge enhances the quality of care provided to pediatric patients with chronic hemolytic anemia.

Correct Answer: D

Rationale: The correct answer is D) Post auricular lymphadenopathy. In rubella, also known as German measles, the presence of post auricular (behind the ear) lymphadenopathy is a pathognomonic sign. This means that this finding is characteristic and specific to rubella. Option A) Severe prodromal stage is not pathognomonic of rubella as many infectious diseases can present with a severe prodromal stage. Option B) Circumoral pallor is not a specific sign of rubella but can be seen in various conditions, including anemia or hypoxia. Option C) Maculopapular rash is a common manifestation of rubella but not pathognomonic as it can also be seen in other viral illnesses. In an educational context, understanding the specific clinical signs of different childhood illnesses is crucial for pediatric nurses to provide accurate and timely care. Recognizing pathognomonic signs like post auricular lymphadenopathy in rubella can aid in prompt diagnosis and appropriate management, ultimately improving patient outcomes.
