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 assessing a patient with a central venous catheter notes the catheter insertion site is red and tender with the patient's temperature 38.8°C (101.8°F). Which of the following actions should the nurse implement?
- A. Administer analgesics and antibiotics.
- B. Check the site frequently for any swelling.
- C. Discontinue the catheter and culture the tip.
- D. Change the flush system and monitor the site.
Correct Answer: C
Rationale: The information indicates that the patient has a local and systemic infection caused by the catheter and the catheter should be discontinued. Changing the flush system, administration of analgesics, and continued monitoring will not help prevent or treat the infection. Administration of antibiotics is appropriate, but the line should still be discontinued to avoid further complications such as endocarditis.
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.
To determine the effectiveness of medications that a patient has received to reduce left ventricular afterload, which of the following hemodynamic parameters should the nurse monitor?
- A. Central venous pressure (CVP)
- B. Systemic vascular resistance (SVR)
- C. Pulmonary vascular resistance (PVR)
- D. Pulmonary artery wedge pressure (PAWP)
Correct Answer: B
Rationale: Systemic vascular resistance reflects the resistance to ventricular ejection, or afterload. The other parameters will be monitored, but do not reflect afterload as directly.
The nurse is weaning a patient who has chronic obstructive pulmonary disease (COPD) from mechanical ventilation. Which of the following patient assessments indicates that the weaning protocol should be discontinued?
- A. The patient heart rate is 98 beats/minute.
- B. The patient's oxygen saturation is 93%.
- C. The patient respiratory rate is 32 breaths/minute.
- D. The patient's spontaneous tidal volume is 500 mL.
Correct Answer: C
Rationale: A respiratory rate of 32 breaths/minute indicates respiratory distress and suggests that the patient is not tolerating the weaning process, necessitating discontinuation of the weaning protocol. A heart rate of 98 beats/minute, oxygen saturation of 93%, and spontaneous tidal volume of 500 mL are within acceptable ranges for weaning.
The family members of a patient who has just been admitted to the intensive care unit (ICU) with multiple traumatic injuries have just arrived in the ICU waiting room. Which of the following actions should the nurse take first?
- A. Immediately take the family members to the patient's room.
- B. Discuss ICU visitation policies and encourage family visits.
- C. Describe the patient's injuries and the care that is being provided.
- D. Invite the family to participate in a multidisciplinary care conference.
Correct Answer: C
Rationale: Lack of information is a major source of anxiety for family members and should be addressed first. Family members should be prepared for the patient's appearance and the ICU environment before visiting the patient for the first time. ICU visiting should be individualized to each patient and family rather than being dictated by rigid visitation policies. Inviting the family to participate in a multidisciplinary conference is appropriate but should not be the initial action by the nurse.
