The nurse is preparing to auscultate a patient's heart sounds. At which location will S1 be heard the loudest?
 
  1. left midclavicular line at the fifth intercostal space
  2. left sternal border at the fifth intercostal space
  3. right midclavicular line at the fifth intercostal space
  4. right sternal border at the third intercostal space

Question 2

When listening to heart sounds, the nurse hears an S3 sound after S2. What should the nurse suspect is occurring with this patient?
 
  1. ventricular volume overload
  2. increased resistance to ventricular filling
  3. inflammation of the pericardial sac
  4. stenotic mitral valve

Answer to Question 1

Correct Answer: 1
S1 is the sound produced by the atrioventricular (AV) valves closing and is heard the best at the left midclavicular line, fifth intercostal space. The sound is audible at the left sternal border, but would not be as loud. This sound would not normally be audible on the right midclavicular line at the fifth intercostal space, nor at the sternal border.

Answer to Question 2

Correct Answer: 1
A pathologic S3 is called a ventricular gallop and results from myocardial failure and ventricular volume overload. An S3 sound is not caused by increased resistance to ventricular filling, inflammation of the pericardial sac, or mitral valve stenosis.
