The nurse is preparing to assist with the insertion of a pulmonary artery catheter in a patient. Which of the following actions will the nurse implement?
- A. Check cardiac enzymes before insertion.
- B. Auscultate heart sounds during insertion.
- C. Place the patient on NPO status before the procedure.
- D. Attach cardiac monitoring leads before the procedure.
Correct Answer: D
Rationale: Dysrhythmias can occur as the catheter is floated through the right atrium and ventricle, and it is important for the nurse to monitor for these during insertion. Pulmonary artery catheter insertion does not require anaesthesia, and the patient will not need to be NPO. Changes in cardiac enzymes or heart sounds are not expected during pulmonary artery catheter insertion.

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.
When the ventilator alarm sounds, the nurse finds the patient lying in bed holding the endotracheal tube (ET). Which of the following actions should the nurse take first?
- A. Offer reassurance to the patient.
- B. Activate the hospital's rapid response team.
- C. Call the health care provider to reinsert the tube.
- D. Manually ventilate the patient with 100% oxygen.
Correct Answer: D
Rationale: The nurse should ensure maximal patient oxygenation by manually ventilating with a bag-valve-mask system. Offering reassurance to the patient, notifying the health care provider about the need to reinsert the tube, and activating the rapid response team also are appropriate after the nurse has stabilized the patient's oxygenation.
The nurse is assisting with insertion of a pulmonary artery (PA) catheter in a patient. Which of the following data identifies that the catheter is correctly placed?
- A. Monitor shows a typical PAOP tracing.
- B. PA waveform is observed on the monitor.
- C. Systemic arterial pressure tracing appears on the monitor.
- D. Catheter has been inserted to the 22-cm marking on the line.
Correct Answer: A
Rationale: One of the purposes of a PA line is to measure PAOP, so the catheter is floated through the pulmonary artery until the dilated balloon wedges in a distal branch of the pulmonary artery, and the PAOP readings are available. After insertion, the balloon is deflated and the PA waveform will be observed. Systemic arterial pressures are obtained using an arterial line. The length of catheter needed for insertion will vary with patient size.
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 take when the low-pressure alarm sounds for a patient who has an arterial line in the right radial artery?
- A. Check the right hand for pallor.
- B. Assess for cardiac dysrhythmias.
- C. Flush the arterial line with saline.
- D. Rezero the monitoring equipment.
Correct Answer: B
Rationale: The low-pressure alarm indicates a drop in the patient's blood pressure, which may be caused by cardiac dysrhythmias. There is no indication to rezero the equipment. Pallor of the right hand would be caused by occlusion of the radial artery by the arterial catheter, not by low pressure. There is no indication of a need for flushing the line.
