The nurse notes a loud, drum like sound during percussion of the stomach and documents as

Appeared in: KGMU 2024

Explanation

Tympany is the correct medical term for the sound described.
This sound is characterized as loud, high-pitched, and drum-like.
It is the expected finding when percussing over an air-filled organ like the stomach or intestines, as the air vibrates freely.
The presence of tympany over the stomach is a normal finding in a physical assessment.

Option B: Dullness is a thud-like sound, not drum-like. It indicates a solid organ or fluid, not an air-filled space like the stomach.
Option C: Resonance is a low-pitched, hollow sound, which is different from the high-pitched, drum-like sound of tympany. It is also associated with a different body system.
Option D: Flatness is a soft, high-pitched sound, indicating very dense tissue with no air present. The stomach is not a dense, solid structure.

Clinical Relevance

Nursing practice connection: Knowing Percussion Sounds in Abdominal Assessment helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Percussion is a fundamental nursing assessment skill used to determine the size, location, and density of underlying organs and to detect the presence of air, fluid, or solid masses.
An unexpected finding, such as dullness over an area where tympany is expected (like the intestines), can indicate a problem such as a tumor, mass, or constipation, requiring further investigation.
What if? If a nurse percusses the abdomen of a patient with a suspected bowel obstruction and hears widespread tympany and hyperresonance, it would suggest a large amount of trapped gas, supporting the diagnosis and indicating the severity of the distention.

How to Approach the Question

First, identify the key elements in the question: the action (percussion), the location (stomach), and the sound description (loud, drum-like).
Recall the different types of percussion sounds and their associated qualities.
Match the description 'loud, drum-like' to the correct medical term. This quality is the classic definition of tympany.
Correlate this sound with the anatomical location. The stomach is a hollow, air-filled organ, which is where tympanic sounds are expected.
Evaluate the other options to confirm they are incorrect. Dullness is for solid organs, resonance for lungs, and flatness for bone/muscle, none of which match the stomach.
