Which is an abnormal finding in a neonate?
**Core Concept**
In neonatology, it's essential to recognize abnormal physical findings that may indicate underlying conditions. This question tests knowledge of normal and abnormal physical examination findings in neonates.
**Why the Correct Answer is Right**
The correct answer is likely related to a physical examination finding that is not typical for a healthy neonate. For example, the presence of a murmur may indicate a congenital heart defect, such as a ventricular septal defect (VSD). A VSD is characterized by an abnormal opening in the ventricular septum, allowing blood to flow from the left to the right ventricle. This can lead to increased flow through the pulmonary artery and subsequent pulmonary hypertension.
**Why Each Wrong Option is Incorrect**
**Option A:** This option may be a normal finding in neonates, such as a patent ductus arteriosus (PDA) that typically closes spontaneously within the first few days of life.
**Option B:** This option may be a normal finding in neonates, such as a soft systolic ejection murmur heard over the left upper sternal border due to the flow of blood through the pulmonary valve.
**Option C:** This option may be an abnormal finding in neonates, but it's not as specific or sensitive as the correct answer. For example, a wide pulse pressure may be seen in conditions such as coarctation of the aorta.
**Clinical Pearl / High-Yield Fact**
In neonates, it's essential to remember that a soft systolic ejection murmur is a common finding and usually not a cause for concern. However, a harsh or holosystolic murmur may indicate a more significant underlying condition, such as a VSD.
**Correct Answer:** C.
