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 physiology involved in a pneumothorax, you are most concerned that:

a. you are not maintaining an adequate seal around the facemask, and thus the patient is not getting enough oxygen. b. the pressure from the BVM 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.
