This heart sounds quiz will test your ability on how well you know the location of heart sounds and the causes of extra heart sounds. As a nurse or nursing student, you are required to know the basic heart sounds S1 (lub) and S2 (dub) and their location, along with extra heart sounds, such as S3, S4, and heart murmurs.
In nursing school (especially health assessment), you will be tested on the pathophysiology, location, and anatomy of the heart blood flow in how it relates to the heart valves. It is important to remember the anatomical location of where each heart valve is found and which sounds it represents (either S1 or S2). In addition, it is vital you know how to properly auscultate for various heart sounds, especially S3, S4 and heart murmurs.
Before you take the quiz, don’t forget to watch the video lecture and skills assessment on heart sounds.
