Nokea
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.

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.
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 an older-adult patient who has stabilized after being in the intensive care unit (ICU) for a week and is preparing for transfer to the step-down unit when the nurse notices that the patient has new onset confusion. Which of the following actions should the nurse implement?
- A. Inform the receiving nurse and then transfer the patient.
- B. Notify the health care provider and postpone the transfer.
- C. Administer PRN lorazepam and cancel the transfer.
- D. Obtain an order for restraints as needed and transfer the patient.
Correct Answer: A
Rationale: The patient's history and symptoms most likely indicate delirium associated with the sleep deprivation with sensory overload in the ICU environment. Informing the receiving nurse and transferring the patient is appropriate. Postponing the transfer is likely to prolong the delirium. Benzodiazepines and restraints contribute to delirium and agitation.
Which of the following information obtained by the nurse when caring for a patient receiving mechanical ventilation indicates the need for suctioning?
- A. The respiratory rate is 17 breaths/minute.
- B. The pulse oximeter shows a SpO2 of 93%.
- C. The lungs have occasional audible expiratory wheezes.
Correct Answer: A
Rationale: The increase in respiratory rate indicates that the patient may have decreased airway clearance and requires suctioning. Suctioning is done when patient assessment data indicate that it is needed, not on a scheduled basis. Occasional expiratory wheezes do not indicate poor airway clearance, and suctioning the patient may induce bronchospasm and increase wheezing. An SpO2 of 93% is acceptable and does not suggest that immediate suctioning is needed.
