The nurse explains that the two divisions of the autonomic nervous system work to maintain homeostasis. Which action is the first autonomic event following a stressful or frightening event?

  • A. Parasympathetic nervous system dominates
  • B. Blood pressure, heart rate, and adrenaline output decrease
  • C. Sympathetic nervous system dominates
  • D. Heart rate and blood pressure rise, secretion of adrenaline
Correct Answer: D

Rationale: In the event of a frightening event, the sympathetic nervous system dominates and increases the blood pressure, heart rate, and adrenaline output in the 'fight or flight' mechanism. The body is calmed by the parasympathetic nervous system dominating and reducing the heart rate, blood pressure, and adrenaline output.
