Final answer:
Normal findings for percussion of the abdomen on an adult client are bowel sounds.
Step-by-step explanation:
When performing percussion of the abdomen on an adult client, the nurse would expect to find normal bowel sounds, which are considered a normal finding. These sounds can range from high-pitched tinkling to low-pitched gurgling. They are produced by the movement of gas and fluid through the intestines. Absent sounds (option A) would indicate an abnormal finding, such as a bowel obstruction. Absolute dullness (option B) is associated with organ enlargement or a solid mass. Musical and drum-like sounds (option C) may indicate the presence of air in the intestines, which is not normal. Pain (option D) could be a sign of underlying pathology and would not be considered a normal finding.
