Begin in the RLQ and percuss lightly to determine the prevailing amount of tympany and dullness. Percuss in at least 3 areas per quadrant. Do not percuss over the midline due to the location of the aorta underneath. Tympanic = air Dull = density; distended bladder, adipose tissue, or a mass Flat = muscle. can you write short but meaning full and no bullet point. Examle tympanic what area, dull what area , and flat what area. Ex: tympanic RUQ, dull in remaining quads
