What is the rationale for these interventions?
A client in acute respiratory distress is brought to the emergency department. After endotracheal (ET) intubation and initiation of mechanical ventilation, the client is transferred to the intensive care unit. Before suctioning the ET tube, the nurse hyperventilates and hyperoxygenates the client.
A. They help prevent subcutaneous emphysema. B. They help prevent pneumothorax. C. They help prevent cardiac arrhythmias. D. They help prevent pulmonary edema.

The correct answer is option C
The nurse hyperventilate and hyperoxygenate the client’s lungs to help prevent cardiac arrhythmias. This is because low level of oxygen can cause cardiac arrhythmia as a result of low oxygen delivery to other parts of the body.
Subcutaneous emphysema is not associated with suctioning, it occurs when air gets into subcutaneous tissue from the pleural cavity.
Hyperventilation and hyperoxygenation cannot prevent pneumothorax. Pneumothorax is the presence of air in the thoracic cavity.
Pulmonary edema cannot be prevented by hyperventilation or hyperoxygenation as this is most likely caused by a problem in the heart.
The hyperventilating and hyperoxygenation a patient will prevent cardiac arrhythmias. This is done because the removal of oxygen lowers the pressure of arterial oxygen which can cause cardiac arrhythmia. Subcutaneous emphysema isn't a problem that is associated with suctioning but occurs when air from the pleural cavity gets into the subcutaneous tissue.
Pneumothorax is not prevented by hyperventilation or hyperoxygenation because it occurs when there is air in the pleural space. Again, hyperventilating and hyperoxygenation cannot prevent pulmonary edema because this condition is a cardiac dysfunction.
They help prevent cardiac arrhythmias.-rationale: et suctioning removes oxygen, lowering the partial pressure of arterial oxygen; this, in turn, may induce a cardiac arrhythmia. hyperventilating and hyperoxygenating the client before and during (or after) suctioning helps prevent this complication. subcutaneous emphysema occurs when air from the pleural cavity leaks into subcutaneous tissue; it isnt a complication associated with suctioning. hyperventilation and hyperoxygenation cant prevent a pneumothorax because this condition itself indicates air in the pleural space. pulmonary edema is associated with cardiac dysfunction, not et suctioning.client needs category: physiological integrityclient needs subcategory: reduction of risk potentialcognitive level: applicationreference: smeltzer, s.c., et al. brunner & suddarths textbook of medical-surgical nursing, 11th ed. philadelphia: lippincott williams & wilkins, 2008, p. 737.
