A 45-year-old man is in the clinic for a physical examination. During the abdominal assessment, the nurse percusses the abdomen and notices an area of dullness above the right costal margin of approximately 11 cm. How should the nurse proceed?

A. Normal finding: This is not a normal finding. Dullness in this area could indicate an enlarged liver (hepatomegaly), which requires further evaluation. B. Enlarged liver: Dullness above the right costal margin, especially around 11 cm, is often associated with hepatomegaly. The nurse should refer the patient to a physician for further investigation. C. Hepatomegaly: While the finding could suggest hepatomegaly, the diagnosis should be confirmed by a physician. The nurse should refer the patient for further evaluation. D. Alcohol intake: While it is relevant to ask about alcohol intake in the context of liver health, the immediate action is to refer the patient for further examination by a physician.
