What are THREE associated echo findings for an infant with wide spaced nipples and a webbed neck?

Correct Answer: D

Rationale: In pediatric cardiovascular nursing, the presence of wide spaced nipples and a webbed neck can be indicative of Turner syndrome, a genetic condition affecting females. This syndrome is associated with various cardiac anomalies that can be detected through echocardiography. The correct answer, option D (All of the above), is correct because Turner syndrome can present with LV systolic dysfunction, blunted abdominal aortic Doppler, and bicuspid aortic valve. Option A (LV systolic dysfunction) is associated with Turner syndrome due to structural cardiac abnormalities that can lead to impaired left ventricular function. Option B (Blunted abdominal aortic Doppler) may be seen in patients with coarctation of the aorta, a condition commonly found in Turner syndrome. Option C (Bicuspid aortic valve) is another common cardiac defect seen in Turner syndrome, affecting the aortic valve structure. Understanding these echo findings in the context of Turner syndrome is crucial for nurses caring for pediatric patients with this condition. Recognizing these cardiac anomalies early through echocardiography can help in timely interventions and management to optimize patient outcomes. Nurses must be knowledgeable about these associations to provide comprehensive care and support to infants with Turner syndrome and other similar genetic conditions affecting the cardiovascular system.

Correct Answer: B

Rationale: In the management of an infant with Tetralogy of Fallot experiencing recurrent desaturation episodes on propranolol, the correct intervention is option B) Interim repair with RVOT stent or shunt. This intervention aims to improve pulmonary blood flow and oxygenation without the need for immediate complete surgical repair, offering a temporary solution while awaiting definitive surgery. Option A) Full surgical repair is not the immediate choice for an infant experiencing recurrent desaturation episodes as it may not address the acute desaturation issue promptly. Option C) Propranolol dose adjustment may not be sufficient to address the underlying physiological cause of the desaturation episodes in Tetralogy of Fallot. From an educational perspective, understanding the rationale behind the choice of interim repair with an RVOT stent or shunt is crucial for pediatric cardiovascular nursing. It demonstrates the importance of balancing immediate intervention with long-term management strategies in complex congenital heart conditions. Educators should emphasize the significance of tailored interventions based on individual patient needs and disease severity in pediatric cardiology.

Correct Answer: A

Rationale: In a newborn with Trisomy 21 (Down syndrome), the most likely congenital heart lesion is Atrioventricular Septal Defect (AVSD). This is due to the association between Trisomy 21 and AVSD, making it a common finding in these patients. AVSD involves abnormalities in the development of the atrial and ventricular septa, leading to a large hole between the atria and the ventricles, as well as abnormalities in the AV valves. Tetralogy of Fallot (Option B) is less commonly associated with Trisomy 21 and consists of four heart defects: pulmonary stenosis, VSD, overriding aorta, and right ventricular hypertrophy. Ventricular Septal Defect (Option C) is a common congenital heart defect but is not specifically associated with Trisomy 21. Pulmonary Stenosis (Option D) is also not the most likely lesion in a newborn with Trisomy 21. Understanding the association between Trisomy 21 and AVSD is crucial for nurses caring for pediatric patients with Down syndrome. Recognizing common congenital heart lesions in these patients can aid in early detection, appropriate management, and improved outcomes. This knowledge is essential for nurses working in pediatric cardiology, neonatal intensive care units, or general pediatric settings where they may encounter children with Trisomy 21 and congenital heart defects.

Correct Answer: D

Rationale: In this scenario, the correct answer is D) Refer to a pediatric cardiologist for further evaluation. When a harsh, blowing grade IV/VI murmur is auscultated in a 6-month-old infant, it raises concerns about a significant cardiac anomaly. Referring the infant to a pediatric cardiologist is crucial because they are specialists who can conduct a thorough evaluation including echocardiography to accurately diagnose the underlying heart condition. Option A) Getting a complete blood count to rule out severe anemia is not the appropriate next step as anemia typically does not cause a harsh, blowing murmur of this magnitude. Option B) Obtaining an electrocardiogram to assess for arrhythmia is not the most appropriate next step as the murmur described is more indicative of a structural heart problem rather than an arrhythmia. Option C) Ordering a chest radiograph to evaluate for cardiomegaly is not the primary next step as an isolated murmur is not typically associated with significant cardiomegaly at this stage. Educationally, this question highlights the importance of differentiating between innocent murmurs and pathologic murmurs in pediatric patients. It emphasizes the need for prompt referral to specialists for further evaluation and management of potentially serious cardiac conditions in infants.

Correct Answer: D

Rationale: In this scenario, the likely diagnosis for the 3-month-old infant presenting with a persistent cough, bilateral lung crackles, poor appetite, a grade III/VI holosystolic murmur over the left lower sternal border, and a palpable liver is a Ventricular Septal Defect (VSD). VSD is a common congenital heart defect that can present with symptoms such as poor feeding, failure to thrive, respiratory distress, and heart murmur. A) Atrial septal defect (ASD) is less likely in this case as the symptoms and physical exam findings are more indicative of a VSD. B) Coarctation of the aorta (COA) typically presents with hypertension in the upper extremities and weak pulses in the lower extremities, which are not evident in this case. C) Patent ductus arteriosus (PDA) would present with a continuous murmur, bounding pulses, and widened pulse pressure, which are not described in the scenario. Educationally, understanding the characteristic clinical manifestations and physical exam findings associated with different congenital heart defects is crucial for pediatric nurses to provide early detection and appropriate management. Recognizing the specific signs and symptoms can lead to timely interventions and improved outcomes for infants with congenital heart defects.
