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 nurse is caring for a patient with pulmonary hypertension. Which of the following parameters should the nurse monitor as an index of right ventricular afterload?
- A. Mean arterial pressure (MAP)
- B. Central venous pressure (CVP)
- C. Pulmonary vascular resistance (PVR)
- D. Pulmonary artery wedge pressure (PAWP)
Correct Answer: C
Rationale: Pulmonary vascular resistance and pulmonary artery pressure are indexes of right ventricular afterload. The other parameters do not directly assess for right ventricular afterload.
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.
The nurse is caring for a patient who has an arterial catheter in the radial artery to monitor blood pressure. Which of the following information obtained by the nurse is most important to report to the health care provider?
- A. The patient has a positive Allen test.
- B. The mean arterial pressure (MAP) is 86 mm Hg.
- C. There is redness at the catheter insertion site.
- D. The dicrotic notch is visible in the waveform.
Correct Answer: C
Rationale: Redness at the catheter insertion site indicates possible infection. The Allen test is performed before arterial line insertion, and a positive test indicates normal ulnar artery perfusion. An MAP of 86 is normal and the dicrotic notch is normally present on the arterial waveform.
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 nurse is caring for a patient following surgery whose central venous pressure (CVP) monitor indicates low pressures. Which of the following actions should the nurse anticipate implementing?
- A. Increase the IV fluid infusion rate.
- B. Administer IV diuretic medications.
- C. Elevate the head of the patient's bed to 45 degrees.
- D. Document the CVP and continue to monitor.
Correct Answer: A
Rationale: A low CVP indicates hypovolemia and a need for an increase in the infusion rate. Diuretic administration will contribute to hypovolemia and elevation of the head may decrease cerebral perfusion. Documentation and continued monitoring is an inadequate response to the low CVP.
