A nurse is caring for an infant who has tetralogy of Fallot. The infant is crying and is experiencing a hypercyanotic spell. Which of the following actions should the nurse take first?
Administer morphine subcutaneously.
Apply a face mask supplying 100% oxygen.
Attempt to calm and soothe the child.
Place the infant in a knee-chest position.
The Correct Answer is B
Choice A rationale:
Morphine subcutaneously can help reduce anxiety and stress, but supplying oxygen is the priority intervention.
Choice B rationale:
During a hypercyanotic spell ("tet spell"), the infant's oxygen levels drop, leading to cyanosis (blue skin) and distress. Administering oxygen can help improve oxygen saturation and alleviate the spell.
Choice C rationale:
Calming and soothing the child may not be sufficient to address the oxygen saturation issue during a hypercyanotic spell.
Choice D rationale:
Placing the infant in a knee-chest position can help improve blood flow, but administering oxygen should be the initial step.

Choice A rationale:
Placing the newborn under a radiant warmer is not directly related to addressing breastfeeding-related jaundice.
Choice B rationale:
