Give this one a try later!In preparing a patient in the ICU for oral ET intubation, what should the nurse do that is most important for successful intubation?

• Place the patient supine with the head extended and the neck flexed.
• Tell the patient that the tongue must be extruded while the tube is inserted.
• Position the patient supine with the head hanging over the edge of the bed to align

the mouth and trachea.

• Inform the patient that while it will not be possible to talk during insertion of the

tube, speech will be possible after it is correctly placed. 1 / 3

• Assist-control ventilation (ACV)
• Pressure support ventilation (PSV)
• Pressure-controlled inverse ratio ventilation (PC-IRV)
• Synchronized intermittent mandatory ventilation (SIMV)

• Referred to as ventilatory failure
• Main problem is inadequate O2 transfer
• Risk of inadequate O2 saturation of hemoglobin exists
• Body is unable to compensate for acidemia of increased partial pressure of carbon

dioxide in arterial blood (PaCO2)

• Most often caused by ventilation-perfusion (V/Q) mismatch and shunt
• Exists when partial pressure of oxygen in arterial blood (PaO2) is less than 60 mm

Hg, even when O2 is given at 60% or more Which descriptions are characteristic of hypoxemic respiratory failure (select all that apply)?
