A nurse is caring for an elderly client who exhibits symptoms of vagus nerve stimulation, a parasympathetic response. Which finding would support stimulation of the vagus nerve?
A) Dilation of the pupil
B) Decreased heart rate
C) Easier time with breathing
D) Clenching of the jaw
B
Feedback:
The nurse should assess the functioning of the vagus nerve in the client by observing if the client has decreased heart rate. The sympathetic nerve function can be assessed by observing the dilation of the pupil of the eye. Easier time with breathing is not caused by vagus nerve stimulation. Cranial nerve V mandibular branch of the trigeminal nerve can be assessed by the clenching of the jaw.
