order from first to last)
A. Chest X-Ray
B. ETCO2 20-40 mmHg
C. Listen to left/right/abdomen
D. Chest symmetry
Answer: B, D, C, A
Rationale: ET tube placement is confirmed in this order: First, ETCO2
reading of 20-40 mmHg (most reliable indicator of tracheal placement),
then chest symmetry (observing equal chest rise), then auscultation of
left/right/abdomen (listening for breath sounds bilaterally and absence
over abdomen), and finally Chest X-Ray (to confirm tip position above
the carina).

breaths

breaths per minute

set tidal volume.

vent mode.
A. The vent does everything for the patient
B. The vent delivers a set amount of breaths per minute
, C. The patient attempts to breathe and the vent assists with their

ventilator assists with their breaths. The ventilator delivers a set
number of mandatory breaths synchronized with the patient's
spontaneous efforts.
