If a client has stimulation of the parasympathetic nervous system, which vital signs would the nurse expect?
Heart rate of 56 bpm, respiratory rate of 20/min.
Heart rate of 72 bpm, respiratory rate of 12/min.
Heart rate of 84 bpm, respiratory rate of 14/min.
Heart rate of 120 bpm, respiratory rate of 10/min.
The Correct Answer is A
Stimulation of the parasympathetic nervous system generally results in a decrease in heart rate (bradycardia) and can also influence respiratory rate. A heart rate of 56 bpm is indicative of parasympathetic activation. While the respiratory rate of 20/min is within the normal range, parasympathetic stimulation primarily affects heart rate more significantly.

Correct Answer is A
Explanation
The rate and depth of respiration in a normal adult are primarily controlled by chemoreceptors. These receptors monitor the levels of carbon dioxide (CO₂), oxygen (O₂), and the pH (acid-base balance) of the blood. They send signals to the respiratory centers in the brain to adjust breathing accordingly to maintain homeostasis.
