The nurse is providing care to a patient who exercises in excess, leading to acidosis. Which patient statement does the nurse evaluate as accurate related to the cause of the acidosis?

7.40
What actions in the body should the nurse anticipate as compensatory mechanisms to regulate pH when providing care to a patient whose oH is less than 7.35?
Chemical buffering system releases bicarbonate
Respiratory system blows off excess carbon dioxide
Kidneys will excrete bicarbonate
Chemical buffering system releases carbonic acid
Respiratory system blows off excess carbon dioxide
Kidneys will excrete bicarbonate
Chemical buffering system releases carbonic acid
The nurse is teaching a patient about the general purpose of bicarbonate in the blood. Which patient response evaluated by the nurse indicates correct understanding?
"It is a weak base that plays a critical role in acid-base balance"
Which statement should the nurse student include in a presentation regarding the mechanism which rids the body of excess hydrogen ions?
kidneys excrete hydrogen ions in the urine
Which response should the nurse expect for a patient whose arterial pH level is 8.0?
the body system will shut down
