An S3 heart sound is auscultated in a client in her third trimester of pregnancy. What intervention should the nurse take?

An S3 heart sound can be a normal finding during pregnancy due to increased blood volume and changes in cardiac output. It is known as a physiological S3 and is considered a benign finding in the absence of other concerning symptoms or signs. In this case, there is no immediate need for intervention or concern regarding the S3 heart sound. It is not necessary to prepare the client for an echocardiogram or limit the client's fluids based solely on the presence of an S3 heart sound in the absence of other significant symptoms or complications. ​​​​​​​
