Acid-Base Balance

  1. 1. A patient has been vomiting for days. He lost a lot of gastric juice. The doctor ordered an ABG. The results are likely to show

  2. Respiratory acidosis
    Metabolic acidosis
    Respiratory alkalosis
    Metabolic alkalosis

  3. pH = 7.50 HCO3- = 50 pCO2 = 40. The patient is in

  4. Respiratory acidosis
    Metabolic acidosis
    Respiratory alkalosis
    Metabolic alkalosis

  5. A patient in respiratory acidosis may have the following ABG result

  6. paO2 = 80
    pCO2 = 10
    pCO2 = 52
    HCO3- = 10

  7. A patient in respiratory alakalosis may have the following ABG result

  8. paO2 = 80
    pCO2 = 10
    pCO2 = 52
    HCO3- = 10

  9. The following is most likely the result for a patient in compensated respiratory alkalosis

  10. pH = 7.30 pCO2 = 40 HCO3- = 23
    pH = 7.30 pCO2 = 60 HCO3- = 37
    pH = 7.50 pCO2 = 20 HCO3- = 12
    pH = 7.50 pCO2 = 20 HCO3- = 24

  11. The following arterial blood pH is acidotic

  12. pH = 7.35
    pH = 7.45
    pH = 7.29
    pH = 7. 49

  13. The following arterial blood pH is normal

  14. pH = 7.35
    pH = 7.55
    pH = 7.30
    pH = 7.20

  15. A patient with diarrhea loses a lot of bicarbonate. The blood pH is expected to be

  16. Low
    High
    Normal
    None of the above

  17. A patient with emesis loses a lot of acid. The blood pH is expected to be

  18. Low
    High
    Normal
    None of the above

  19. A patient who is hyperventilating is likely to be in

  20. Respiratory acidosis
    Respiratory alkalosis
    Metabolic acidosis
    Metabolic alkalosis
