Answer to Question 1

ANS: A
Pulse oximetry is based on the principles of spectrophotometry and photoplethysmograph y.

Answer to Question 2

ANS: A
Bilirubin levels of greater than 20 mg/dL of whole blood will alter measurements, because biliru-bin absorbs near-IR and IR light. Absorbance of light by bilirubin lowers the actual O2Hb meas-ured.
