#1
Front (Question)

Henderson-Hasselbalch Equation:

Back (Answer)

pH = pKa + log (Conj base/Weak acid) pH = 6.1 + log (Bicarbonate/Carbonic Acid)

7.35 - 7.45

#3
Front (Question)

Reference Value of pCO2

Back (Answer)

35-45 mmHg

#4
Front (Question)

Reference Value of HCO3

Back (Answer)

21-28 mEq/L

#5
Front (Question)

Reference Value of pO2

Back (Answer)

81-100 mmHg

#6

#10
Front (Question)

Compensation for Metabolic Alkalosis

Back (Answer)

Hypoventilation Decreased breathing rate

Back (Answer)

Respiratory Acidosis

#12
Front (Question)

Compensation for Respiratory Acidosis

Back (Answer)

Kidneys retain HCO3 because of increased pCO2
