A nurse on the pediatric unit is caring for an Infant. Drag words from the choices below to fill in each blank in the following sentence. It would be a priority for the nurse to dropdown and dropdown.

The infant with Tetralogy of Fallot is showing signs of clinical deterioration, including worsening hypoxia, fever, hypotension, decreased urine output, and increasing lethargy. The infant’s decreasing oxygen saturation, irregular respirations, and poor perfusion suggest worsening tissue oxygenation and possible progression toward shock or hypoxic crisis. In pediatric cardiac conditions, especially cyanotic heart defects, airway, breathing, and circulation take priority, with immediate emphasis on oxygenation and vascular access for emergency management. Rationale for correct choices: • Apply 100% oxygen via facemask: Applying high-concentration oxygen is the immediate priority because the infant is experiencing worsening hypoxemia, as evidenced by declining oxygen saturation, cyanosis, and respiratory distress. In Tetralogy of Fallot, oxygen delivery to tissues is already compromised due to right-to-left shunting, and acute illness can further worsen hypoxia. Oxygen administration helps maximize available oxygen in the bloodstream and reduce systemic hypoxic stress. • Initiate a peripheral IV: Establishing IV access is critical because the infant is showing signs of systemic instability, including hypotension, fever, decreased urine output, and lethargy. IV access allows for rapid administration of fluids, antipyretics, antibiotics if infection is suspected, and emergency medications if deterioration continues. In pediatric emergencies, vascular access is essential for correcting perfusion deficits and supporting circulation. Rationale for incorrect choices: • Administer acetaminophen: Although the infant has a fever, antipyretic administration is not the immediate priority in the presence of respiratory distress, hypoxia, and poor perfusion. Fever may be contributing to increased metabolic demand, but correcting oxygenation and circulation takes precedence. Administering acetaminophen does not address the life-threatening hypoxia or potential shock state. It can be considered after stabilization of airway, breathing, and circulation. • Auscultate breath sounds: Assessment of breath sounds is important but is not a priority intervention at this stage because the infant already shows clear signs of systemic deterioration requiring immediate action. Respiratory assessment provides useful data, but delaying oxygen therapy and vascular access could worsen outcomes. In rapidly deteriorating pediatric patients, treatment interventions take priority over additional assessments once critical instability is identified. • Reassure the parent: Providing reassurance is important for family-centered care, but it is not a priority in a life-threatening situation involving hypoxia and potential shock. The infant is demonstrating worsening oxygen saturation, hypotension, and decreased responsiveness, which require immediate intervention. While communication with the parent should occur, it must not delay oxygen administration or IV access.
