When a respiratory therapist is assessing with the insertion of a nasal endotracheal tube, the following should be done: 1. Hyperoxygenation should be performed before the intubation is attempted 2. A curved blade should be attached to the laryngoscope handle to lift the epiglottis 3. The head and neck should be put into the sniffing position 4.

An order is received to begin postural drainage, percussion, and vibration on an 18-year-old female. The chest radiograph film shows the superior and inferior segments of the left lingula are opaque. Auscultation reveals crackles in this area.  The respiratory therapist would proceed to do all the following: 1. Tip the patient’s head down 15 degrees 2. Explain the importance of the treatment 3. Rotate the patient one-fourth turn up from supine 4. Percuss and vibrate in the left anterior chest area
