Answer to Question 1

ANS: A
In response to trauma, the sympathetic arousal symptoms of rapid heart rate and rapid respiration prepare the person for flight or fight responses. Afterward, the dorsal vagal response damps down the sympathetic nervous system. This is a parasympathetic response with the heart rate and respiration slowing down and decreasing the blood pressure. Relaxation techniques promote activity of the parasympathetic nervous system.

Answer to Question 2

ANS: C
The scenario presents chronic and potentially debilitating stress. If arousal continues unabated, neuronal changes occur that alter the neural circuitry of the prefrontal cortex, reducing the size the hippocampus so that memory is impaired.
