An elderly patient with a history of congestive heart failure was just admitted for chest pain. The patient asks a nurse, "Why did my chest pain begin after I thought someone was trying to break into my house?" The best response by the nurse is:
1. "Response to fear increases the body's demand for oxygen, which can place additional stress on your damaged heart and cause chest pain."
2. "The parasympathetic system used all of your available adrenaline, leaving you so tired that you developed chest pain."
3. "Because the release of cortisol blocks the body's response to fear, you weren't allowed sufficient time to rest, which can cause chest pain."
4. "The decrease in oxygen use during the fight-or-flight response is most likely the reason that you developed chest pain."
