During a tetralogy of Fallot spell, what is the nurse's priority action for an infant?

In the context of a tetralogy of Fallot spell, the priority action for the nurse is to calm the infant. During such spells, the infant experiences a sudden decrease in oxygenated blood flow, which can lead to hypoxia. The infant may exhibit signs of distress, such as difficulty breathing, cyanosis, and irritability. By calming the infant, the nurse can help reduce the metabolic demands on the heart and improve the infant's overall comfort, potentially alleviating some of the physiological stress associated with the spell.

Calming strategies may include holding the infant in a comforting position, using soothing voices, or employing gentle touch. These approaches can help decrease the infant's anxiety and may momentarily stabilize their condition by promoting relaxation.

Other interventions, while important in the overall management of the condition, may not be as immediately effective as providing comfort during an acute episode.
