A 28-year-old with seizure disorder has a vagus nerve stimulator implanted to help control sei-zure activity. Which result will the nurse expect to occur?
a. Increased speed of cardiac cycle
b. Increased cardiac contractility
c. Decreased vasodilation
d. Decreased cardiac conduction
ANS: D
The vagus nerve releases acetylcholine. Acetylcholine causes decreased heart rate and slows conduction through the AV node, thus decreasing the speed of the cardiac cycle. This reaction also decreases contractility but does not cause decreased vasodilation.
