Which of the following findings indicate normal heart sounds?

Normal heart sounds are characterized by the typical "lub-dub" sounds produced during the cardiac cycle. The first heart sound (S1) occurs with the closure of the atrioventricular valves, and the second heart sound (S2) occurs with the closure of the semilunar valves. When assessing for normal heart sounds, the absence of additional abnormal sounds is essential.

Murmurs, rubs, and gallops represent abnormal heart sounds. Murmurs are extra or unusual sounds that result from turbulent blood flow, indicating potential heart valve issues or other cardiovascular problems. Rubs are associated with pericarditis and often indicate inflammation of the pericardial sac. Gallops refer to the presence of additional heart sounds, such as S3 or S4, which can indicate various cardiac conditions like heart failure or myocardial ischemia.

Thus, identifying normal heart sounds means recognizing the standardized sounds of S1 and S2 without the presence of these abnormal findings. The reference to "Normal Heart Sounds" confirms that these sounds are standard and expected in a healthy heart assessment.
