Which finding during percussion would suggest splenomegaly?

The correct finding indicating splenomegaly during percussion would be when there is a change from tympany to dullness over the left anterior axillary line to the left sternal border. This is because the spleen is typically a softer organ located on the left side of the abdomen, and when it enlarges, it can cause dullness to be felt upon percussion due to the increased tissue density associated with the enlarged spleen.

When performing percussion, a normal finding over the spleen area should typically be tympanic, as this area often contains air-filled structures. However, when the spleen enlarges, it displaces the air, resulting in dullness during percussion. Thus, the shift from tympany to dullness is a key indicator of splenomegaly.

The other findings in the options describe percussion changes that do not correlate with the expected findings associated with splenomegaly. For instance, changes from dullness to tympany would not typically signify splenic enlargement and rather indicate other underlying conditions such as excess gas in the intestines or variances in normal organ positioning. Understanding these distinctions is crucial for identifying clinical conditions accurately.
