In the circulatory system, bicarbonate leaves the RBC and enters the plasma through an exchange mechanism with ___ to maintain electroneutrality.
Chloride
Carbonic acid concentration in blood plasma equals:
0.0307 mmol/L Hg times the pCO2 value in mmHg
The anticoagulant of choice for arterial blood gas measurements is ____ in the ___ state.
Lithium heparin ; dry
Hypoventilation can compensate for:
Nonrespiratory alkalosis
When arterial blood from a normal patient is exposed to room air:
pCO2 increases; pO2 decreases
Oxygen content in blood reflects:
pO2 value, O2Hb, O2 dissolved in blood plasma, The patient's total hemoglobin value (all of the above)
The presence of dyshemoglobins will cause a calculated % So2 result to be falsely____and a pulse oximeter % SpO2 value to be falsely___.
elevated, elevated
The kidneys compensate for respiratory alkalosis by ____ of bicarbonate and ___ excretion of NaH2PO4:
Excretion, decreased
The hemoglobin oxygen binding capacity for a blood sample that is 100% saturated with O2 and has a total hemoglobin value of 12 g/dL is approximately:
17 mL O2/ dL
The normal ratio of carbonic acid to bicarbonate in arterial blood is:
1:20
At a pH of 7.10, the H+ concentration is equal to:

A patient's arterial blood gas results are as follows pH 7.37, pCO2 75, HCO3 37. These values are consistent with:
Compensated respiratory acidosis
A patient's arterial blood gas results are as follows: pH 7.48, pCO2 54, HCO3 38. These values are consistent with:
