A nurse in the emergency department is caring for a client who was injured in a motor-vehicle crash. The client reports dyspnea and severe pain. The nurse notes that the client's chest moves inward during inspiration and bulges out during expiration. The nurse should identify this finding as which of the following?
Pneumothorax
Atelectasis
Flail chest
Hemothorax
The Correct Answer is C
Choice A Reason: This is incorrect because a pneumothorax is a condition in which air enters the pleural space and causes the lung to collapse. It does not cause the chest wall to move inward and outward paradoxically.
Choice B Reason: This is incorrect because atelectasis is a condition in which alveoli collapse and cause reduced gas exchange. It does not cause the chest wall to move inward and outward paradoxically.
Choice C Reason: This is correct because flail chest is a condition in which multiple ribs are fractured and cause a segment of the chest wall to detach from the rest of the thoracic cage. It causes the chest wall to move inward and outward paradoxically, as well as dyspnea and pain.
Choice D Reason: This is incorrect because a hemothorax is a condition in which blood enters the pleural space and causes the lung to collapse. It does not cause the chest wall to move inward and outward paradoxically.

Correct Answer is B
Explanation
Choice A Reason: This is incorrect because preparing for mechanical ventilation is not the priority nursing intervention, as it is an invasive and potentially harmful procedure that should be reserved for clients who have severe respiratory failure and cannot maintain adequate oxygenation with noninvasive methods.
Choice B Reason: This is correct because administering oxygen via face mask is the priority nursing intervention, as it is a noninvasive and effective way to improve oxygenation and reduce hypoxemia in a client who has low PaO2 and SaO2. Oxygen therapy can also decrease the workload of the heart and lungs and prevent further complications.
Choice C Reason: This is incorrect because preparing to administer a sedative is not the priority nursing intervention, as it may worsen the client's respiratory status and mask the signs and symptoms of hypoxemia. Sedatives should be used with caution and only after oxygenation has been optimized.
Choice D Reason: This is incorrect because assessing for indications of pulmonary embolism is not the priority nursing intervention, as it is a diagnostic rather than a therapeutic action. Pulmonary embolism is a possible cause of the client's condition, but it does not address the immediate problem of hypoxemia.
Correct Answer is D
Explanation
Choice A Reason: This choice is incorrect because warm, flushed skin is not a sign of respiratory acidosis. Warm, flushed skin may indicate fever, infection, inflammation, or allergic reaction, but it does not reflect the acid-base imbalance in the blood.
Choice B Reason: This choice is incorrect because hyperactive deep tendon reflexes are not a sign of respiratory acidosis. Hyperactive deep tendon reflexes may indicate hypocalcemia, hyperthyroidism, or spinal cord injury, but they do not reflect the carbon dioxide level in the blood.
Choice C Reason: This choice is incorrect because bounding peripheral pulses are not a sign of respiratory acidosis. Bounding peripheral pulses may indicate increased cardiac output, anxiety, or hyperthyroidism, but they do not reflect the pH level in the blood.
Choice D Reason: This choice is correct because widened QRS complexes are a sign of respiratory acidosis. QRS complexes are the segments on an electrocardiogram (ECG) that represent the depolarization of the ventricles. A normal QRS complex duration is 0.06 to 0.10 seconds, and a widened QRS complex duration is more than 0.12 seconds. A widened QRS complex may indicate hyperkalemia, which is a common complication of kidney failure and respiratory acidosis. Hyperkalemia is a condition in which the serum potassium level is higher than normal (more than 5 mEq/L). It may cause cardiac arrhythmias, muscle weakness, or paralysis.
