While suctioning a client, vagal stimulation occurs. What is the appropriate nursing action?

A. Coughing may exacerbate vagal stimulation, potentially worsening bradycardia or hypotension. This is not a safe immediate action during a vagal response. B. Vagal stimulation during suctioning can trigger bradycardia, hypotension, or even arrhythmias. The priority nursing action is to stop suctioning immediately and provide 100% oxygen to prevent hypoxemia and maintain tissue perfusion while monitoring the heart rate and vital signs. Supplemental oxygen helps stabilize the patient until the vagal response resolves. C. While Fowler’s position can improve ventilation, it does not directly counteract vagal stimulation or prevent bradycardia. Positioning alone is insufficient in this acute situation. D. Teaching deep breathing is a preventative strategy for general respiratory care but is not effective in an acute vagal response. The patient may already be physiologically compromised, making immediate oxygenation and monitoring the priority.
