Which of the following findings would indicate an aortic stenosis murmur?

Aortic stenosis typically presents with a characteristic systolic ejection murmur. This murmur is best heard at the right second intercostal space and often radiates to the carotid arteries in the neck due to the anatomical path and the direction of blood flow. The radiation to the neck is a notable feature that helps differentiate this specific murmur from others that might occur in the heart.

Understanding the nature of this murmur involves recognizing that aortic stenosis leads to turbulent blood flow as it passes through the narrowed aortic valve during systole. The radiation of the sound to the neck occurs because the carotid arteries are located in close proximity to the aorta and the path of blood flow. This is a hallmark sign that clinicians look for during auscultation to confirm the presence of aortic stenosis.

Other findings listed, such as a systolic murmur radiating to the axilla or diastolic murmurs, do not align with typical characteristics of aortic stenosis. Murmurs that radiate to the axilla are more indicative of mitral regurgitation, while diastolic murmurs pertain to conditions like aortic regurgitation or mitral stenosis and do not represent the typical sound associated with
