Which action occurs when your body releases stress hormones?
a. reaction speed increases b. pain response increases
c. blood flow decreases
d. the number of brain cells increases

The answer to this question is . B, pain response increases

Option A is wrong because when you release stress hormone, you enter fight-or-flight mode which will actually slow down your reaction speed
Option C is wrong because stress hormone triggers your heart rate, which also increases blood flow.
Option D is wrong because when you're stressed, you release cortisol that actually slowed down the production of brain cells

20 times a minute is usually the average respritory rate of an adult. additionally the patient is breathing on his own, is clearly maintaining his airway, and is intaking a sufficient amount of air. you shouldn't use a bag valve mask, cpap, or other form of positive pressure ventilation, unless the patient has lost control of his airway, and is not breathing (apneic) or has rapid breathing or slow and shallow respirations. this patient would most likely and should be put on an non-rebreather mask or nrb attached to 100% high flow oxygen at 15 l/min. don't use a nasal cannula, as the amount of oxygen it provides is limited with a rate of 6 l/min.
