The nurse is caring for a patient with heart failure requiring a ventricular assist device (VAD) implanted and is waiting for cardiac transplantation. Which of the following actions should the nurse include in the plan of care?
- A. Administer of immuno-suppressive medications.
- B. Monitor the surgical incision for signs of infection.
- C. Teach the patient the reason for continuous bed rest.
- D. Prepare the patient to have the VAD in place permanently.
Correct Answer: B
Rationale: The insertion site for the VAD provides a source for transmission of infection to the circulatory system and requires frequent monitoring. Patients with VADs are able to have some mobility and may not be on bed rest. The VAD is a bridge to transplantation, not a permanent device. Immuno-suppression is not necessary for nonbiological devices like the VAD.

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.
When a patient's pulmonary artery catheter becomes wedged and does not reflect pulmonary artery pressures, which of the following actions should the nurse take?
- A. Reposition the patient and check for a pulmonary artery tracing.
- B. Deflate the balloon and flush the catheter with saline.
- C. Notify a health care provider or specially trained nurse.
- D. Increase the volume in the balloon to open the catheter.
Correct Answer: C
Rationale: When the catheter is in the wedge position, blood flow past the catheter is obstructed, placing the patient at risk for pulmonary infarction. A health care provider or specially trained nurse should be called to reposition the catheter. The other actions will not correct the wedging of the PA catheter.
Which of the following information obtained by the nurse when caring for a patient receiving mechanical ventilation indicates the need for suctioning?
- A. The respiratory rate is 17 breaths/minute.
- B. The pulse oximeter shows a SpO2 of 93%.
- C. The lungs have occasional audible expiratory wheezes.
Correct Answer: A
Rationale: The increase in respiratory rate indicates that the patient may have decreased airway clearance and requires suctioning. Suctioning is done when patient assessment data indicate that it is needed, not on a scheduled basis. Occasional expiratory wheezes do not indicate poor airway clearance, and suctioning the patient may induce bronchospasm and increase wheezing. An SpO2 of 93% is acceptable and does not suggest that immediate suctioning is needed.
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 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.
