Answer to Question 1

ANS: B
Intense daylight and fluorescent, incandescent, xenon, and infrared light sources have caused errors in pulse oximetric readings. Anemia and deeply pigmented skin can affect the accuracy of pulse oximetry; however, the effect of anemia is not clinically significant until the hemoglobin level is markedly reduced.

Answer to Question 2

ANS: C
Normal resting O2 consumption is approximately 250 ml/min and O2 consumption increases with activity, stress, and temperature.
