You are incorrect - This patient's acoustic events at the apex include a first heart sound, a holosystolic murmur, a single second heart sound and a mid diastolic murmur.
Your choice: Holosystolic murmur + S3 + S4
This is a graphic example of an S1, a holosystolic murmur, a single S2, S3 and S4. Let us listen to and observe these events together. Note that the events in diastole are discreet sounds and that no diastolic murmur occurs.
