Answer to Question 1

ANS: A
To guide practitioners in providing quality care, the AARC has published Clinical Practice Guideline: Pulse Oximetry. Modified excerpts from the AARC guideline appear on p. 389.

Answer to Question 2

ANS: C
Proper sensor-electrolyte contact is essential, as is proper application to the skin surface. A loose-ly applied sensor may have air leaks or may become dislodged. In either case, the resulting meas-urements will approach those in room air:
PO2 = 159 mm Hg
PCO2 = 0 mm Hg
