Answer to Question 1

ANS: B
A pH of 7.24 indicates acidosis because it is below 7.35. The PaCO2 of 55 mm Hg is a respirato-ry acidosis because it is greater than 45 mm Hg. The arterial blood gas is partially compensated because the HCO3 of 27 mEq/L is greater than 26 mEq/L and the pH is less than 7.35.

Answer to Question 2

ANS: D
The electrolyte and the sensor's membrane should be checked regularly and changed weekly or whenever a signal drift during calibration is noticed.
