Extract:
Question 1 of 5
The nurse is reviewing the arterial blood gas (ABG) result for a client currently on a 100% non-rebreather mask. The nurse is able to interpret which of the following results as hypoxemic respiratory failure?
Correct Answer: A
Rationale: PaO2 of 44 mmHg and O2 saturation of 76% despite 100% oxygen indicate hypoxemic respiratory failure, characterized by severe hypoxemia.
Question 2 of 5
When caring for a client with a chest tube, the nurse would avoid the practice
Correct Answer: B
Rationale: Stripping the chest tube can increase intrathoracic pressure, risking tension pneumothorax, and is an outdated practice.
Question 3 of 5
The nurse is caring for a client who is 3 hours post-operative following a right lobectomy for lung cancer. The client has shallow respirations at a rate of 14/minute with guarding of the operative site. The breath sounds are diminished throughout the left lung field. The nurse assigns the highest priority to which intervention to prevent acute respiratory failure?
Correct Answer: D
Rationale: Adequate pain relief is critical to promote deep breathing and prevent shallow respirations, reducing the risk of atelectasis and respiratory failure.
Question 4 of 5
The nurse is to begin a nitroglycerin infusion for a client diagnosed with an anterior wall myocardial infarction. Which assessment finding should the nurse report to the provider immediately?
Correct Answer: D
Rationale: A blood pressure of 90/50 mmHg is significantly low and could indicate hypotension, a known side effect of nitroglycerin infusion. This can compromise perfusion to vital organs and may require adjustment or discontinuation of the infusion, making it the most urgent finding to report.
Question 5 of 5
A client with a medical diagnosis of acute respiratory distress syndrome (ARDS) is being placed in the prone position. The nurse explains to family members that, 'This will help improve ventilation by:
Correct Answer: A
Rationale: Prone positioning improves ventilation in ARDS by allowing better airflow to less-damaged posterior lung regions, enhancing oxygenation.
