NCLEX Acute Respiratory Failure and
ARDS UPDATED ACTUAL Exam
Questions and CORRECT Answers
ANS: C
ABG analysis is most useful in this setting because ventilatory failure causes problems with
CO2 retention, and ABGs provide information about the PaCO2 and pH. The other tests also
may be done to help in assessing oxygenation or determining the cause of the patient's
ventilatory failure.
DIF: Cognitive Level: Application REF: 1752-1754
TOP: Nursing Process: Assessment MSC: NCLEX: Physiological Integrity - CORRECT
ANSWER- ✔✔To evaluate the effectiveness of prescribed therapies for a patient with
ventilatory failure, which diagnostic test will be most useful to the nurse?
a. Chest x-rays
b. Pulse oximetry
c. Arterial blood gas (ABG) analysis
d. Pulmonary artery pressure monitoring
ANS: A
Increasing oxygen flow rate usually will improve oxygen saturation in patients with
ventilation-perfusion mismatch, as occurs with pulmonary embolism. Because the problem is
with perfusion, actions that improve ventilation, such as deep-breathing and coughing, sitting
upright, and suctioning, are not likely to improve oxygenation.
DIF: Cognitive Level: Application REF: 1747-1749 | 1754
TOP: Nursing Process: Implementation MSC: NCLEX: Physiological Integrity - CORRECT
ANSWER- ✔✔While caring for a patient who has been admitted with a pulmonary
embolism, the nurse notes a change in the patient's oxygen saturation (SpO2) from 94% to
88%. The nurse will
a. increase the oxygen flow rate.
b. suction the patient's oropharynx.
c. assist the patient to cough and deep breathe.
d. help the patient to sit in a more upright position.
, ANS: B
The patient's lethargy, low respiratory rate, and SpO2 indicate the need for mechanical
ventilation with ventilator-controlled respiratory rate. Administration of high flow oxygen
will not be helpful because the patient's respiratory rate is so low. Insertion of a mini-
tracheostomy will facilitate removal of secretions, but it will not improve the patient's
respiratory rate or oxygenation. BiPAP requires that the patient initiate an adequate
respiratory rate to allow adequate gas exchange.
MSC: NCLEX: Physiological Integrity - CORRECT ANSWER- ✔✔A patient with
respiratory failure has a respiratory rate of 8 and an SpO2 of 89%. The patient is increasingly
lethargic. The nurse will anticipate assisting with
a. administration of 100% oxygen by non-rebreather mask.
b. endotracheal intubation and positive pressure ventilation.
c. insertion of a mini-tracheostomy with frequent suctioning.
d. initiation of bilevel positive pressure ventilation (BiPAP).
ANS: C
The patient's assessment indicates that assisted coughing is needed to help remove secretions,
which will improve oxygenation. A 2-hour rest period at this time may allow the oxygen
saturation to drop further. Humidification will not be helpful unless the secretions can be
mobilized. Positioning on the right side may cause a further decrease in oxygen saturation
because perfusion will be directed more toward the more poorly ventilated lung.

TOP: Nursing Process: Implementation MSC: NCLEX: Physiological Integrity - CORRECT
ANSWER- ✔✔The pulse oximetry for a patient with right lower lobe pneumonia indicates
an oxygen saturation of 90%. The patient has rhonchi, a weak cough effort, and complains of
fatigue. Which action is best for the nurse to take?
a. Position the patient on the right side.
b. Place a humidifier in the patient's room.
c. Assist the patient with staged coughing.
d. Schedule a 2-hour rest period for the patient.
