When you are suctioning an adult patient, the onset of bradycardia is most likely due to:
A) hypercarbia.
B) hypoxia.
C) stimulation of the vagus nerve.
D) increased intracranial pressure.

Question

Quizplus · Accepted Answer

Bradycardia during suctioning in adult patients is most likely due to stimulation of the vagus nerve. This can occur when the suction catheter stimulates the back of the throat or the carina, resulting in a reflex response that slows the heart rate. It is important to monitor the patient's heart rate and stop suctioning if bradycardia occurs. Hypercarbia, hypoxia, and increased intracranial pressure can also cause bradycardia, but they are less likely during suctioning.
