The nurse is with a young patient who has just been informed of his terminal illness. His heart rate increases, his eyes dilate, and his blood pressure increases. The nurse recognizes this response as what?
A) Part of the limbic system response
B) Sympathetic nervous response
C) Hypothalamic-pituitary response
D) Local adaptation syndrome
Ans: B
Feedback: The sympathetic nervous system responds rapidly to stress; norepinephrine is released at nerve ending causing the organs to respond (i.e., heart rate increases, eyes dilate, and blood pressure increases). Option A is incorrect; the limbic system is a mediator of emotions and behavior that are critical to survival during times of stress. Option C is incorrect; the hypothalamic-pituitary response regulates the cortisol-induced metabolic effect that results in elevated blood sugars during stressful situations. Option D is incorrect; local adaptation syndrome is a tissue-specific inflammatory reaction.
