QuestionSBA
QuestionChoice
This is incorrect. Hyperventilation typically results in respiratory alkalosis due to blowing off excess CO2. To compensate, the kidney will reduce the reabsorption of bicarbonate so that there is a lower plasma bicarbonate to buffer the H+ ions, bringing the pH back down. Bicarbonate is primarily reabsorbed at the proximal convoluted tubule.

e
There will be no effect on bicarbonate reabsorption
QuestionChoice
This is incorrect. Whilst bicarbonate is primarily reabsorbed through the proximal convoluted tubule, in this case, bicarbonate reabsorption will decrease. Hyperventilation typically results in respiratory alkalosis due to blowing off excess CO2. To compensate, the kidney will reduce the reabsorption of bicarbonate so that there is a lower plasma bicarbonate to buffer the H+ ions, bringing the pH back down.

d
Bicarbonate reabsorption, primarily through the distal convoluted tubule, will increase
QuestionChoice
This is incorrect. Whilst bicarbonate reabsorption will decrease to bring the pH down, bicarbonate is primarily reabsorbed at the proximal convoluted tubule, not the distal convoluted tubule.

A patient suffering from an anxiety attack begins hyperventilating.

Given the likely acid-base disturbance caused by this hyperventilation, how will the kidney respond with respect to bicarbonate reabsorption in the nephron?
