Answer to Question 1

ANS: D
The most common sites for electrode placement are the abdomen, chest, and lower back.

Answer to Question 2

ANS: D
This is because accurate transcutaneous measures require adequate skin perfusion. Low cardiac output, shock, and dehydration all cause peripheral vasoconstriction and impair capillary flow, which lowers the PtcO2 level.
