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.

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 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.
When assisting with oral intubation of a patient who is receiving mechanical ventilation, place the following actions in the correct order.
- A. Preoxygenate with a bag-valve-mask system for 3-5 minutes.
- B. Place the patient in a supine position.
- C. Perform a chest x-ray to verify tube placement.
- D. Inflate the cuff on the endotracheal tube.
- E. Use an end-tidal CO2 sensor to check tube placement.
Correct Answer: B,E,C,D,A
Rationale: The patient is placed in a supine position and preoxygenated with a bag-valve-mask system for 3-5 minutes before intubation. Following the intubation, the cuff on the endotracheal tube is inflated to occlude and protect the airway. Tube placement is assessed first with an end-tidal CO2 sensor, and then with a chest x-ray.
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.
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.
