Answer to Question 1

ANS: D
ABGs should be measured 20 to 30 min after initiation of mechanical ventilation.

Answer to Question 2

ANS: C
An extra endotracheal tube or tracheostomy tube of the correct size should be placed at the pa-tient's bedside, and the equipment needed to replace the airway must be available and easily ac-cessible. A clean, functioning manual resuscitator with O2 supply and suction equipment, includ-ing an appropriate supply of suction catheters, sterile water or saline solution, and sterile gloves also must be placed near the bedside.
