Answer to Question 1

ANS: B
Pulse oximeters use spectrophotometry to determine the amount of hemoglobin in a blood sam-ple. They use optical plethysmography to estimate the heart rate by measuring cyclic changes in light transmission through the sample site during each cardiac cycle.

Answer to Question 2

ANS: B
The presence of bilirubin in quantities greater than 20 mg/dL of whole blood can alter measure-ments because it absorbs near-infrared (IR) and IR light. Absorbance of light by bilirubin lowers the actual O2Hb measured.
