all of the above are correct
Which of these chemicals is able to help in compensating for metabolic acidosis?
bicarbonate ion
Inadequate exhalation of carbon dioxide can cause
blood pH to decrease
Which condition may result in respiratory alkalosis?
cerebrovascular accident
Buffer systems
function to convert strong acids or bases into weak acids or bases

h2co3
A person who is hyperventilating may
have respiratory acidosis
All of these conditions could cause respiratory acidosis EXCEPT
hyperventilation
Respiratory Acidosis may be caused by
hypoventilation
An increase in the level of H+ ions in the ECF would cause
increased renal secretion of H+

prolonged vomiting of stomach contents
An acid is an ionic compound that
releases H+ when it dissociates
Emphysema may cause
respiratory acidosis

Which of the following is the most common cause of metabolic alkalosis?
vomiting
