Answer to Question 1
ANS: A
Moisture can interfere with securing the endotracheal (ET) tube, especially if tape is used. The nurse should assess the placement of the tube and then clean and dry the skin. The oral cavity should be suctioned as often as needed. Raising the head of the bed will not decrease secretions (and may cause pooling of secretions in the child's mouth) and may lead to skin problems if the child slides down in bed frequently.
Answer to Question 2
ANS: A
When a mechanically ventilated patient suddenly desaturates (oxygen saturation drops), the nurse responds using the DOPE mnemonic (displaced tube, obstructed tube, pneumothorax, equipment problem). The most common cause is a displaced tube, so the nurse should assess this first.
