The nurse examines a client's abdomen. Which finding indicates an abnormal response when palpating the spleen?

A. A firm mass at the bottom of the left rib cage could indicate an enlarged spleen. Splenomegaly can result from various conditions such as infections, liver disease, or blood disorders. This finding is considered abnormal and warrants further evaluation. B. Rebound tenderness in the right upper quadrant is used to assess for peritoneal irritation, often associated with conditions such as appendicitis. This finding is not specific to the spleen but rather indicates potential issues in the right side of the abdomen, and is not directly related to palpation of the spleen. C. The spleen is normally not palpable in most people. If the tip of the spleen is palpable during deep palpation or when the client is asked to exhale forcefully, it may indicate mild splenomegaly. While this finding might suggest an abnormality, it is less alarming than a firm, consistently palpable mass. D. McBurney’s point is located in the right lower quadrant and is used to assess for appendicitis. Pain at McBurney’s point is related to appendiceal inflammation and is not specific to the spleen. This finding does not provide information about the spleen but rather about potential appendiceal pathology.
