Answer to Question 1

ANS: D
Oximetry is the measurement of blood hemoglobin saturations using spectrophotometry.

Answer to Question 2

ANS: B
Because the sensor is heated, clinicians must take care to avoid thermal injury to the patient's skin. This is accomplished by (1) careful monitoring of sensor temperature (the safe upper limit is approximately 42 C) and (2) regularly rotating the sensor site.
