While family members are visiting, a patient has a cardiac arrest and is being resuscitated. Which of the following actions by the nurse is best?
- A. Ask family members if they wish to remain in the room during the resuscitation.
- B. Explain to family members that watching the resuscitation will be very stressful.
- C. Assign a staff member to wait with family members just outside the patient room.
- D. Escort family members quickly out of the patient room and then remain with them.
Correct Answer: A
Rationale: Research indicates that family members want the option of remaining in the room during procedures such as CPR and that this decreases anxiety and facilitates grieving. The other options may be appropriate if the family decides not to remain with the patient.

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 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.
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.
Which of the following actions should the nurse implement to verify the correct placement of an endotracheal tube (ET) after insertion?
- A. Auscultate for the presence of bilateral breath sounds.
- B. Obtain a portable chest radiograph to check tube placement.
- C. Observe the chest for symmetrical movement with ventilation.
- D. Use an end-tidal CO2 monitor to check for placement in the trachea.
Correct Answer: D
Rationale: End-tidal CO2 monitors are currently recommended for rapid verification of ET placement. Auscultation for bilateral breath sounds and checking chest expansion also are used, but they are not as accurate as end-tidal CO2 monitoring. A chest x-ray confirms the placement but is done after the tube is secured.
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.
