limits. Late inspiratory crackles are heard on auscultation over the left lower
lung posteriorly. When the clinician listens over that area and instructs the
patient to say "ee," it sounds like "A." Which of the following would most
likely be found on percussion of his lungs?
a. Flatness
b. Hyperresonance
c. Stridor
d. Tympany

A 14-year-old high school student comes to the clinic for a 3-month history of
periodic dyspnea when playing basketball. It resolves shortly after resting. He
has not had fever, chills, cough, sputum production, or chest pain. He has no

would be most suggestive of asthma?
a. Mediastinal crunch
b. Pleural rub
c. Rhonchi
d. Wheezes
e. Stridor - ANSWER-d. Wheezes
A 24-year-old veteran returns from his second tour of duty in the Middle East.
