Which of the following findings is considered a normal physical examination finding in a pregnant patient?

An increased second heart sound split with inspiration is a normal finding in a pregnant patient due to the increased blood volume and changes in hemodynamics that occur during pregnancy. As the diaphragm elevates and the thoracic cavity volume decreases, there can be physiological changes in the heart sounds. This phenomenon is attributed to the increased blood flow across the heart valves and the physiological adaptations in cardiac output that accompany pregnancy, leading to this normal variation.

In contrast, a diastolic murmur, while it might be present, can sometimes indicate more complex cardiovascular changes and may not always be regarded as a benign finding in the context of pregnancy. Facial edema can also be a sign of potential problems, as it may indicate preeclampsia, a serious pregnancy complication. Hyperreflexia can indicate conditions such as central nervous system involvement, which could also signify serious neurological issues. Thus, the increased splitting of the second heart sound is the most consistently normal finding among pregnant individuals.
