The nurse is caring for a client in the cardiac unit who has a systolic murmur. Which assessment finding would the nurse expect when auscultating this client’s heart sounds?

  1. The murmur can be heard between S3 and S4.
  2. The murmur can be heard between S4 and S1.
  3. The murmur can be heard between S2 and S1.
  4. The murmur can be heard between S1 and S2.
Number 4 is correct.
Rationale: A systolic murmur occurs between the S1 and S2 heart sounds. A diastolic murmur will be heard between S2 and S1. Options 1 and 2 are incorrect for hearing a systolic murmur. A murmur can occur during any phase of the cardiac cycle.
