In a coin test, a coin held against the chest is tapped by another coin on the side where the puncture is suspected.
The liver span is a measurement performed during physical examination to determine the size of the liver and identify possible hepatomegaly.. It is the distance between the lower border of the liver in the mid-clavicular line obtained by palpation, and the upper border of the liver in the mid-clavicular line detected by percussion (the upper border of the liver lies behind the ribs and can not ...
