Complete the bowtie diagram by identifying the most likely condition, selecting two expected assessment findings, and choosing two priority nursing interventions

The nurse reviews the infant's chart to plan care. Complete the diagram by dragging and dropping the choices below each heading.

Rationale:

• Ventricular septal defect (VSD): Logan shows poor weight gain, mild crackles in all lung fields, mild subcostal retractions, and a heart murmur. These are classic early signs of a left-to-right shunt caused by a VSD, leading to pulmonary overcirculation, increased work of breathing, and feeding difficulties in infants.
• Coarctation of the aorta: Typically presents with differential blood pressures between upper and lower extremities, weak or absent femoral pulses, and may show cyanosis or poor perfusion in lower extremities. Logan’s pulses are equal and blood pressure differences are minimal, making this less likely.
• Pulmonary stenosis: Often manifests with cyanosis, right ventricular hypertrophy, or a systolic ejection murmur at the upper left sternal border. Logan has no cyanosis at rest, and his murmur pattern suggests VSD rather than outflow obstruction.
• Hypoplastic left heart syndrome (HLHS): Presents with severe cyanosis, poor perfusion, and signs of cardiogenic shock in the neonatal period. Logan is alert, has normal oxygen saturation, and mild respiratory findings, which makes HLHS unlikely.
• Tachypnea with feeding: Infants with VSD often exhibit increased respiratory rate during exertion, such as feeding, due to pulmonary overcirculation. This compensatory mechanism reflects increased work of breathing to maintain adequate oxygenation.
• Sweating during feedings: This occurs because the heart must work harder to pump blood through the left-to-right shunt, especially during energy-demanding tasks like feeding. It indicates early heart failure symptoms in infants with VSD.
• Bounding peripheral pulses: This is more typical in conditions with increased stroke volume or patent ductus arteriosus (PDA) rather than isolated VSD. Logan’s pulses are normal, so bounding pulses are not expected.
• Cyanosis at rest: Cyanosis is not characteristic of a simple VSD with left-to-right shunt because oxygenated blood is still adequately delivered systemically. Logan’s oxygen saturation is 96% on room air, confirming absence of cyanosis.
• Prolonged capillary refill time (4–5 seconds): A prolonged capillary refill suggests poor systemic perfusion or shock. Logan is alert, warm, and has normal perfusion, making this finding unlikely.
• Feed on demand: Allowing the infant to feed according to hunger cues helps optimize caloric intake without causing fatigue. Infants with VSD have limited endurance, and on-demand feeding prevents exhaustion while improving weight gain.
• Encourage frequent small feedings: Smaller, more frequent feedings reduce energy expenditure per session, prevent fatigue, and improve overall nutritional status. This intervention is essential for infants with increased work of breathing.
• Monitor blood pressure closely: While important for some cardiac conditions like coarctation of the aorta, VSDs rarely cause systemic hypertension or require intensive BP monitoring in the acute setting.
• Provide iron supplementation: Iron supplementation is not routinely indicated for infants with VSD unless anemia is diagnosed. It does not address the primary issue of poor feeding and heart failure symptoms.
• Limit each feeding to 20 minutes: Strictly limiting feeding time may reduce caloric intake and worsen weight gain. Instead, feeding should accommodate the infant’s tolerance and energy level rather than imposing a strict time limit.
