Which procedure involves listening to sounds within an organ using a stethoscope?

The procedure that involves listening to sounds within an organ using a stethoscope is auscultation. This technique is commonly used in medical practice to assess the condition of the heart, lungs, and other internal organs by listening to the sounds they produce. For instance, healthcare providers can detect abnormal lung sounds indicating conditions like pneumonia or bronchitis or evaluate heart sounds for irregularities.

Other techniques, such as percussion, involve tapping on the surface of the body to assess underlying structures, and palpation refers to using the hands to feel the body’s organs and tissues to gather information about their size, shape, firmness, and location. Inspection is the visual examination of a patient’s body for signs of disease. While all these methods are important in the physical assessment process, auscultation specifically focuses on the auditory evaluation, making it the correct answer in this context.
