Exam 22: Acid-Base Balance

One of the ways the kidneys help raise the pH of the body is by excreting NaH₂PO₄ rather than Na₂HPO₄.

When acid is added to a buffered solution, the pH will actually rise.

A solution with a pH of 8

Which of the following body fluids has the lowest pH?

Hyperventilation syndrome can cause metabolic alkalosis.

A solution with a pH of 13 contains more hydroxide ions than a solution with a pH of 11.

Pure water, with a pH of 7, is neither acid nor base because it contains neither hydrogen ions nor hydroxide ions.

Blood leaving the lungs has a _____ than blood entering the lungs.

Blood in the pulmonary vein has a lower pH than the blood in the superior vena cava.

If a base were added to the buffer pair H₂CO₃-NaHCO₃, the concentration of NaHCO₃ would drop.

Which of the following body fluids has the highest pH?

A condition called respiratory acidosis can be caused by a carbonic acid excess. What can cause a carbonic acid excess?

Metabolic acidosis is compensated with the loss of enough NaHCO₃ to bring the ratio back up to 20 times more H₂CO₃.

A condition called metabolic acidosis can be caused by a bicarbonate deficit. What can cause a bicarbonate deficit?

Which of the following is caused by bicarbonate deficit?

Match each term with its corresponding description or definition. -Condition that is caused by a carbonic acid excess

If the buffer pair is to function properly, there must be 20 times more H₂CO₃ than there is NaHCO₃.

One of the things that the kidneys can do that the lungs cannot do is to excrete base.

What is a fixed acid? Give an example of a fixed acid and a nonfixed acid found in the body.

If the buffer pair is to function properly, there must be 20 times more NaHCO₃ than there is H₂CO₃.
