The nurse is working in a phase iii trial. what would be the objectives of the trial?

Phase III trials are awesome. I love everything about phase III trials, except for the fact that I have no clue what they are. I hope this helps!!

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
