Answer to Question 1

Correct Answer: 1
When PEEP is applied, intrathoracic pressure increases further; this can significantly decrease venous return, ventricular filling, stroke volume, and cardiac output. Manifestations of decreased cardiac output include hypotension. Increasing PEEP levels can cause declining blood pressure. Hypotension is not commonly caused by the adjustment of other modes on the ventilator.

Answer to Question 2

Correct Answer: 1, 3, 4, 5
The patient with a nasal endotracheal tube can develop a tracheoesophageal fistula and/or pressure necrosis of the nares from the pressure exerted against the tissues by the tube, as well as sinusitis if sinus drainage is blocked. The tube can be displaced or obstructed. Wound infection can occur with a tracheostomy.
