Overview of Acid-base balance
Question | Answer |
---|---|
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 | “Anaerobic respiration is causing lactic acid to form, leading to acidosis.” |
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 venous pH values should the nurse report to the primary care practitioner as within normal limits? | - 7.35 - 7.40 |
The nurse does an arterial blood gas analysis (ABG) to monitor a patient’s pH. Which arterial pH should the nurse interpret as being normal? | 7.40 |
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. |
What actions in the body should the nurse anticipate as compensatory mechanisms to regulate pH when providing care to a patient whose pH is less than 7.35? | -Chemical buffering system releases bicarbonate. -Respiratory system blows off excess carbon dioxide. |
Which is the primary chemical buffer to correct an acid-base imbalance within a patient’s urine? | Phosphates |
