Final answer:
To find the jugular notch, you can feel for a shallow, U-shaped border at the top of the manubrium. The sternal angle can be located at the angle where the manubrium meets the body of the sternum. When palpating the chest during an exam, use your fingertips to systematically feel for abnormalities.
Step-by-step explanation:
To find the jugular notch, you can feel for a shallow, U-shaped border at the top of the wider, superior portion of the sternum called the manubrium. This notch is also known as the suprasternal notch and is located at the anterior base of the neck, between the medial ends of the clavicles.
To locate the sternal angle, you can palpate or feel for a slight angle or ridge along the sternum where the manubrium meets the body of the sternum. This angle, also known as the angle of Louis, is typically found at the level of the second rib.
When palpating the chest during an exam, you can use your fingertips to systematically feel for any abnormalities, such as lumps, masses, or swelling. Starting at the top of the chest, you can move your fingers in a gentle circular motion, gradually moving downwards and covering the entire chest area.
