Clarify Question
What is the key concept addressed by the question?
· This question is asking you to extrapolate the effects of an injury to the chest.
What type of thinking is required?
· Apply level:
o You are being asked to take what you already know and apply it to predict the consequences of an injury.
Gather Content
What do you already know about the respiratory passages? What other information is related to the question?
· Air travels from the nose and/or mouth down the pharynx and larynx, and into the trachea. The trachea splits into the left and the right bronchus, which carry air separately into the lungs.
· Broken ribs can result in the puncture of a lung if the ribs are pushed inward during trauma.
Choose Answer
Given what you now know, what information is most likely to produce the correct answer?
· If Tim’s right chest wall has been compromised by the accident, collapse of his right lung could occur. Unless the trauma went through to the left side of the chest, his left lung would be unaffected. Over-inflation of the lungs would not occur.
Reflect on Process
Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
· Apply level:
o Answering this question correctly depended on your ability to use the anatomy of the lungs in a new situation. If you got an incorrect answer, did you remember that the function of one lung is not dependent on the function of the other lung, or that an injury to one lung can result in the collapse of that lung? Did you have trouble extending the anatomy of the lungs to determine the correct answer?
