What happens to hydrogen ions and bicarbonate in acidosis? Correct
Answer-Hydrogen ions increase because of the increase in CO2 (CO2 is
an acid) or decrease in bicarb.
What happens to hydrogens ions and HCO3 in alkalosis? Correct
Answer-reduction of hydrogen ions as evidenced by a decrease in the
pCO2 or increase in the HCO3.
How will the body compensate in respiratory acidosis? Correct Answer--
the cell buffering will occur primarily through hemoglobin and proteins
which leads to the production of HCO3 within the kidneys.
, - If the CO2 remains persistently elevated, then there is an increased
excretion of titratable acid and ammonium by the kidneys leading to the
development of HCO3.
How will the body compensate in respiratory alkalosis? Correct
Answer-- cellular buffering occurs in which bicarbonate is combined to
hydrogen ions (excrete).
- Ultimately, there is a decrease in the overall plasma bicarb. The
kidneys over time will increase bicarbonate excretion as well as various
other components to help decrease overall plasma bicarbonate.
How will the body compensate for metabolic acidosis? Correct Answer--
compensation is attempted by decreasing the pCO2.
- How is this accomplished?
- The patient will become tachypneic to blow off extra CO2. The patient
attempts to do this by increasing their tidal volume or rate of breathing.
How will the body compensate for metabolic alkalosis? Correct
Answer-- compensation is attempted by increasing the pCO2.
- There is a decrease alveolar ventilation. The patient may take shallow
or less breaths to hold onto more CO2.
What's the goal of acid-base compensation? Correct Answer-- to return
pH as close to physiologically as normal
Cause of respiratory acidosis Correct Answer-· CNS Depression
