The nurse who is working on a pediatric unit receives shift report for 4 neonates with congenital heart defects. The neonate with which report requires the most immediate intervention?

A. Tetralogy of Fallot (TOF) with hypercyanotic (TET) spells is crying: A hypercyanotic spell indicates acute hypoxemia due to increased right-to-left shunting. Crying worsens the condition by increasing oxygen demand. Immediate intervention such as placing the infant in a knee-chest position and administering oxygen or morphine is required. B. Coarctation of aorta has an elevated blood pressure in upper extremity: This is an expected finding in coarctation of the aorta, as blood flow to the upper body is higher than in the lower extremities. Although it requires monitoring, it is not an emergency situation. C. Patent ductus arteriosus is fatigued after feedings: Fatigue with feedings is a common symptom in infants with PDA due to increased workload on the heart. This finding warrants ongoing assessment but is not immediately life-threatening. D. Ventricular septal defect (VSD) has audible murmurs: A murmur is a typical finding with VSD and results from blood flow between the ventricles. It should be documented and monitored, but it does not indicate an acute deterioration requiring urgent action.
