Bruce is an 80 year-old man transferred from a nursing home with
fever, chills, dysuria, and increasing confusion. An ABG has been
drawn. What is his interpretation?
pH 7.30
CO2 30
HCO3 14
PO2 77
SaO2 89% -
correct answer ✅Bruce has partially compensated metabolic
acidosis with mild hypoxemia.
pH is low = acidosis
CO2 is low = alkalosis
HCO3 is low = acidosis
pO2 is 77 = mild hypoxemia.

What is Bruce's body doing to compensate for his acid-base
imbalance?
a) Shifting the oxygen hemoglobin curve to the left to increase
oxygen supply and increase carbonic acid production
b) Increasing H+ to maintain acidity to promote cell recovery
c) Decreasing his respiratory rate to retain CO2 to reduce the
amount of carbonic acid therefore increasing the pH
d) Increasing his respiratory rate to eliminate CO2 to reduce the
amount of carbonic acid and therefore increasing the pH -
correct answer ✅Increasing his respiratory rate to eliminate CO2
to reduce the amount of carbonic acid and therefore increasing the
pH

Which of the following interventions would you expect to improve
Bruce's pO2? Select all that apply.
Question options:
a) Administer Tylenol
b) Administer warm fluids
c) Request a social worker consult
d) Administer supplemental oxygen
Administer a unit of PRBCs -
correct answer ✅Give O2 = increases O2 supply
Give blood = increased O2 supply
Give Tylenol = decreased O2 demand
Dara is a 23 year-old who has been admitted to the ED with
intractable vomiting. What's her ABG interpretation?
Ph 7.50, CO2 36, HCO3 27, pO2 92, SaO2 97% -
correct answer ✅Dara has uncompensated metabolic alkalosis
with no hypoxemia.
pH is high = alkalosis
PCO2 is low normal = normal

Answers (Grade A+)
HCO3 is high = alkalosis
p02- normal
SaO2- normal = no hypoxemia
Dara is a 23 year-old who has been admitted to the ED with
intractable vomiting. Dara has uncompensated metabolic alkalosis
with no hypoxemia.
Which of the following is the most likely cause of Dara's ABG
results?
Question options:
a) Muscle breakdown from excessive vomiting
b) Loss of stomach acid through vomiting
c) Dara is pregnant
d) Excessive use of anti-emetics -
correct answer ✅Loss of stomach acid through vomiting
Dara is losing large amounts of acids through vomiting of gastric
secretions, leading to a metabolic alkalosis. Hydrogen chloride is
lost from the body, so the bicarbonate that is added to the
extracellular fluid is not neutralized by the subsequent secretion of
