The nurse observes the anesthesiologist confirm the placement of the endotracheal tube (ET) using two different methods: a primary method and a secondary method. A secondary method of confirmation of ET placement includes:
A) Visualization of the ET through the vocal cords
B) Auscultation of breath sounds in five areas on the chest
C) Use of a CO2 detector
D) Bilateral chest expansion
Ans: C
Feedback: Because of the risk of unrecognized esophageal intubation or dislodgement of the ET, tracheal intubation must be confirmed by two different methods: a primary method and a secondary method. Primary methods of ET placement confirmation include visualization of the ET through the vocal cords, auscultation of breath sounds in five areas on the chest, or bilateral chest expansion. The only method of secondary ET confirmation involves the use of a CO2 detector.
