Answer to Question 1

ANS: A
The lungs normally compensate quickly for metabolic acid-base defects because ventilation can change the PaCO2 within seconds. The kidneys require more time to retain or excrete significant amounts of HCO3, and thus compensate for respiratory defects at a much slower pace.

Answer to Question 2

ANS: C
The kidneys compensate by retaining HCO3, returning the plasma HCO3/dissolved CO2 ratio to almost 20:1. The conversion of PCO2 to mEq is done by multiplying by 0.03.
Thus 60  0.03 = 1.8. 36 to 1.8 is equal to a 20 to 1 ratio, thus the pH should be 7.40.
