An OEC candidate indicates that she understands the difference between a pneumothorax and a tension pneumothorax when she makes which of the following statements?
A) “A tension pneumothorax causes blood to accumulate around the lung; a pneumothorax involves the accumulation of air only around the lung.”
B) “A tension pneumothorax can cause cardiac output to decrease; a pneumothorax does not.”
C) “A pneumothorax describes a collapsed lung; a tension pneumothorax involves both a collapsed lung and blood loss.”
D) “A pneumothorax is caused by a closed chest injury; a tension pneumothorax is caused by an open chest injury.”

You are treating a 26-year-old man with a pneumothorax. The patient’s breathing has been inadequate, and you have been assisting his ventilations with a bag-valve mask. The patient’s condition seems to be worsening. Because you understand the pathology involved in a pneumothorax, you are most concerned that:
A) you are not maintaining an adequate seal around the face mask, and thus the patient is not getting enough oxygen.
B) the pressure from the bag valve mask is causing more air to enter the pleural space and is causing a tension pneumothorax.
C) the patient’s airway is not being maintained, so you should insert an oropharyngeal airway.
D) you may have missed an injury.
