The nurse suspects an older adult client has congestive heart failure. Which of the following did the nurse most likely assess in the client?

A. S4 heart sound: An S4 heart sound is often associated with hypertensive heart disease or left ventricular hypertrophy, rather than congestive heart failure alone. B. Harsh holosystolic murmur at the apex: This type of murmur is more indicative of mitral regurgitation rather than congestive heart failure. C. S3 heart sound: An S3 heart sound is commonly associated with congestive heart failure, especially when there is volume overload and decreased left ventricular function. D. Carotid bruits: Carotid bruits are associated with vascular issues rather than congestive heart failure.
