During suctioning of a ventilator-dependent client, severe bradycardia occurs. What should the nurse do immediately?

In the context of suctioning a ventilator-dependent client, severe bradycardia indicates an acute response, likely related to vagal stimulation caused by the suctioning process. When a patient experiences bradycardia, it is critical to ensure their oxygenation is optimized. Administering manual ventilation with 100% oxygen immediately addresses potential hypoxia and supports the patient's respiration during this distressing situation.

When oxygenation is prioritized, it helps stabilize the patient's condition. Suctioning can stimulate the vagus nerve and trigger bradycardia, so responding quickly by ensuring the patient receives adequate oxygen is essential. This intervention not only helps manage the immediate complication but also allows the nurse to reassess the situation and consider further actions, such as discussing the need for any other interventions or monitoring the patient's condition more closely.

Oxygenating the client manually allows for a more controlled approach to managing the patient's immediate needs, while other options, such as continued suctioning or contacting the respiratory therapist, could exacerbate the bradycardia or delay necessary intervention.
