While intubated for surgery, a patient has inadvertently had his vagus nerve stimulated. What effect would the surgical team expect to observe?
A)
Decreased vascular perfusion due to parasympathetic stimulation
B)
Decreased heart rate, contractility, and afterload
C)
Decreased heart rate as a result of parasympathetic innervation of the heart
D)
Decreased heart rate as a result of impaired acetylcholine reuptake
Ans:
C
Feedback:
Vagal stimulation results in lowered heart rate as a result of parasympathetic stimulation. Vascular perfusion, contractility, and afterload would not be under direct effect. Acetylcholine reuptake would not be influenced.
