Answer to Question 1

ANS: D
Based on these factors, transcutaneous monitoring is a reasonable choice when there is a need for continuous, noninvasive analysis of gas exchange in hemodynamically stable infants or children. In these patients, the PaO2 can be calibrated against the PtcO2, thus decreasing the need for re-peated arterial samples. Because pulse oximetry cannot provide accurate estimates of excessive blood oxygen, the transcutaneous monitor also is useful for monitoring hyperoxia in neonates.

Answer to Question 2

ANS: B
To guide practitioners in providing quality care, the AARC has published Clinical Practice Guideline: Transcutaneous Blood Gas Monitoring for Neonatal and Pediatric Patients. Modified excerpts from the AARC guideline appear on p. 385.
