Answer 1

ANS. A. Yes, we can hear bruit sound if a vessel occluded completely by atherosclerosis.

Explanation - Bruit sound is associated with abnormal turbulent flow in a vessel. In atherosclerosis, the narrowing of arteries takes place due to plaque formation. plaque is made of cholesterol, fat, calcium, etc. when around 80% of the narrowing of arteries occurs then bruit is auscultated in both systole and early diastole. In case of complete occlusion, two things can happen - the disappearance of bruit or diminution of bruit. in the latter one, diminution happens but still, there is a chance where we can hear a bruit sound.

ANS. B. Yes, we can hear murmur sounds in a healthy person.

Explanation - murmuring sound in the heart is caused by the turbulent flow of blood in the heart. it can also occur in a normal heart or if some disease is present. mostly the turbulent flow is normal. children between the age of 3 to 7 have a harmless murmur which is also known as an innocent murmur. it can also be heard at the time when a person has done his/her exercise.

Hence all the examples stated above refer to healthy people.
