[{'content': 'Nurse Ruth assessing a patient for tracheal displacement should know that the trachea will deviate toward the \nSelect and explain. \nA. Contralateral side in a simple pneumothorax, B. Affected side in a hemothorax, C. Affected side in a tension pneumothorax, D. Contralateral side in hemothorax', 'role': 'user'}, {'content': 'Answer: D \nExplanation: The\xa0trachea\xa0will shift according to the pressure gradients within the thoracic cavity. \nIn tension\xa0pneumothorax\xa0and\xa0hemothorax, accumulation of air or fluid causes a shift away from the injured side. \nIf there is no significant air or fluid accumulation, the\xa0trachea\xa0will not shift.\nTracheal deviation toward the contralateral side in simple\xa0pneumothorax\xa0is seen when the thoracic contents shift in response to the \nrelease of normal thoracic pressure gradients on the injured side.', 'role': 'assistant'}]
