When You Hyperventilate (Breathe Too Fast), Respiratory Alkalosis (Elevated Blood

question 33

Multiple Choice

When you hyperventilate (breathe too fast) , respiratory alkalosis (elevated blood pH) can occur, which can cause you to faint. A common but potentially dangerous method to reverse respiratory alkalosis is to hold a paper bag over your mouth and take normal breaths, thereby rebreathing the exhaled air. How might this method reverse respiratory alkalosis?

• A)Inhaling oxygen exhaled into the bag will cause oxygen to diffuse back into the blood and react with water to form carbonic acid, and blood pH will decrease.
• B)Inhaling oxygen exhaled into the bag will cause oxygen to diffuse back into the blood and react with water to form carbonic acid, and blood pH will increase.
• C)Inhaling carbon dioxide exhaled into the bag will cause carbon dioxide to diffuse back into the blood and react with water to form carbonic acid, and blood pH will increase.
• D)Inhaling carbon dioxide exhaled into the bag will cause carbon dioxide to diffuse back into the blood and react with water to form carbonic acid, and blood pH will decrease.
