You wish to determine the nature of the fluid accumulating in the left pleural cavity, since that will dictate the appropriate treatment. What structures will your 19 g needle penetrate as you pass from skin to fluid at the midaxillary line below the ninth rib? E Answer saved Marked out of 1.00 Select one: O a.
