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.

Four hours after mechanical ventilation is initiated for a patient with chronic obstructive pulmonary disease (COPD), the patient's arterial blood gas (ABG) results include a pH of 7.50, PaO2 of 80 mm Hg, PaCO2 of 29 mm Hg, and HCO3 of 23 mmol/L. The nurse will anticipate the need to do which of the following actions based upon these findings?
- A. Increase the FIO2.
- B. Decrease the respiratory rate.
- C. Increase the tidal volume (VT).
- D. Leave the ventilator at the current settings.
Correct Answer: B
Rationale: The patient's PaCO2 and pH indicate respiratory alkalosis caused by too high a respiratory rate. The PaO2 is appropriate for a patient with COPD, increasing the tidal volume would further lower the PaCO2, and the PaCO2 and pH indicate a need to make the ventilator changes.
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 with a left radial arterial line. Which of the following assessments indicates a need for the nurse to take action?
- A. The left hand is cooler than the right hand.
- B. The mean arterial pressure (MAP) is 75 mm Hg.
- C. The system is delivering only 3 mL of flush solution per hour.
- D. The flush bag and tubing were last changed 3 days previously.
Correct Answer: A
Rationale: The change in temperature of the left hand suggests that blood flow to the left hand is impaired. The flush system needs to be changed every 96 hours or per agency policy. A mean arterial pressure (MAP) of 75 mm Hg is normal. Flush systems for hemodynamic monitoring are set up to deliver 3-6 mL/hour of flush solution.
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 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.
