What is the immediate action a nurse must take if a mechanically ventilated client pulls out the endotracheal tube?

When a mechanically ventilated client removes their endotracheal tube, the primary concern is maintaining the airway and ensuring adequate oxygenation. The immediate action of preparing for re-intubation is essential because without the endotracheal tube, the client is at significant risk for compromised airway and potential respiratory failure.

Re-intubation may be necessary to provide adequate ventilation and prevent hypoxia. While assessing the patient's vital signs and notifying other team members like respiratory therapy are important components of overall patient care, the urgency of the situation demands that the nurse focus on securing the airway first. Delaying this action could lead to serious complications or worsening of the client's condition. Therefore, preparing for re-intubation is the most critical and immediate response in this scenario.
