Nokea
The nurse notes that a patient's endotracheal tube (ET), which was at the 21-cm mark, is now at the 24-cm mark and the patient appears anxious and restless. Which of the following actions should the nurse take first?
- A. Listen to the patient's lungs.
- B. Offer reassurance to the patient.
- C. Bag the patient at an FIO2 of 100%.
- D. Notify the patient's health care provider.
Correct Answer: A
Rationale: The nurse should first determine whether the ET tube has been displaced into the right mainstem bronchus by listening for unilateral breath sounds. If so, assistance will be needed to reposition the tube immediately. The other actions also are appropriate, but detection and correction of tube malposition are the most critical actions.

The charge nurse is mentoring a new RN staff member providing care to a patient receiving mechanical ventilation. Which of the following actions by the new RN indicates the need for more education?
- A. The RN increases the FIO2 up to 100%.
- B. The RN secures a bite block in place using adhesive tape.
- C. The RN positions the patient with the head of bed at 10 degrees.
- D. The RN asks for assistance to turn the patient to the prone position.
Correct Answer: C
Rationale: The head of the patient's bed should be positioned at 30-45 degrees to prevent ventilator-acquired pneumonia. The other actions by the new RN are appropriate.
Which of the following actions should the nurse implement to verify the correct placement of an endotracheal tube (ET) after insertion?
- A. Auscultate for the presence of bilateral breath sounds.
- B. Obtain a portable chest radiograph to check tube placement.
- C. Observe the chest for symmetrical movement with ventilation.
- D. Use an end-tidal CO2 monitor to check for placement in the trachea.
Correct Answer: D
Rationale: End-tidal CO2 monitors are currently recommended for rapid verification of ET placement. Auscultation for bilateral breath sounds and checking chest expansion also are used, but they are not as accurate as end-tidal CO2 monitoring. A chest x-ray confirms the placement but is done after the tube is secured.
The nurse is caring for a patient with a head injury intubated and placed on a mechanical ventilator. When monitoring the patient, which of the following findings should the nurse report to the health care provider?
- A. Oxygen saturation of 94%.
- B. Respirations of 18 breaths/minute.
- C. Green nasogastric tube drainage.
- D. Increased jugular venous distention.
Correct Answer: D
Rationale: Increases in JVD in a patient with head injury may indicate an increase in intra-cranial pressure (ICP) and that the PEEP setting is too high for this patient. A respiratory rate of 18, saturation of 94%, and green nasogastric tube drainage are normal.
The nurse is caring for a patient who has acute pancreatitis and the mixed venous oxygen saturation (SvO2) is decreasing. Which of the following parameters should the nurse assess to determine the possible cause of the decreased SvO2?
- A. Weight
- B. Amylase
- C. Temperature
- D. Urinary output
Correct Answer: C
Rationale: Elevated temperature increases metabolic demands and oxygen use by tissues, resulting in a drop in oxygen saturation of mixed venous blood. Information about the patient's weight, urinary output, and amylase will not help in determining the cause of the patient's drop in SvO2.
The nurse is caring for a patient who is in cardiogenic shock requiring an intra-aortic balloon pump (IABP). Which of the following assessment findings indicates that the goals of treatment with the IABP are being met?
- A. Heart rate of 110 beats/minute
- B. Urine output of 20 mL/hour
- C. Cardiac output (CO) of 5 L/minute
- D. Stroke volume (SV) of 40 mL/beat
Correct Answer: C
Rationale: A CO of 5 L/minute is normal (range is 4-8 L/minute) and indicates that the IABP has been successful in treating the shock. The low SV signifies continued cardiogenic shock. The tachycardia and low urine output also suggest continued cardiogenic shock.
