Additional heart sounds such as S3 and S4 should be reported to the health care provider to assess for which problems?

• A. Anemia
• B. Cardiac problems
• C. Respiratory infection
• D. Kidney disease

Answer: (B)

S3 and S4 reveal changes in how the heart fills and how compliant the ventricles are, pointing to cardiac problems. An S3 occurs after S2 when rapid ventricular filling happens; in adults it often signals volume overload or heart failure due to reduced pumping efficiency. An S4 happens just before S1 when the atria contract to push blood into a stiff, noncompliant ventricle; it’s commonly tied to long-standing hypertension, left ventricular hypertrophy, or ischemic heart disease. Because these sounds suggest heart-related conditions rather than issues like anemia, infection, or kidney disease, they should be reported for evaluation of potential cardiac problems. Further workup may include an echocardiogram, ECG, BNP, and assessment of blood pressure and fluid status to identify and manage the underlying cardiac issue.
