A young adult is brought to the emergency department after taking a handful of drugs. The client is unresponsive, so an endotracheal tube (ETT) is inserted. How should the nurse determine if the ETT is correctly placed? Select all that apply.

Assess for symmetrical chest movement.

Obtain a portable chest x-ray to verify ETT location.

Monitor ETT markings between 22 and 26 cm at teeth line.

Check for capillary refill of 3 seconds or less.

Auscultate for presence of bilateral breath sounds.
