Which action would the nurse take first when responding to an apnea monitor alarm that signifies a 10-second cessation of respirations?

Choice A rationale When an apnea monitor alarms for a brief, 10-second cessation of respirations, the safest and most immediate intervention is to provide gentle tactile stimulation to the infant, such as lightly rubbing the chest or back. This low-level intervention is often sufficient to prompt the infant to resume breathing without resorting to more aggressive measures like ventilation, which could potentially cause hyperventilation or injury. Choice B rationale Checking the monitor for malfunction is important, but a 10-second alarm is clinically significant and requires immediate assessment and intervention before assuming equipment error. Since a 10-second pause is a potential physiological event, the immediate priority is to address the infant's respiratory status first to prevent hypoxemia, then assess the monitor if the infant's breathing status permits. Choice C rationale Rescue breaths with oxygen are reserved for prolonged apnea episodes, typically 20 seconds or longer, or when the infant is profoundly cyanotic, unresponsive, and apneic, indicating a need for positive pressure ventilation. For a short 10-second alarm without severe distress, gentle tactile stimulation is the appropriate initial response to stimulate the central nervous system. Choice D rationale Assessing for changes in skin color, such as pallor or cyanosis, should be done simultaneously with or immediately after providing tactile stimulation, as a change in color is an indication of poor oxygenation. The primary action remains intervention to restart breathing, as assessment alone does not treat the apnea and must be followed by a prompt therapeutic action.
