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.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
