North American Registry of Midwives (NARM) Practice Exam

What percentage of newborns are reported to have murmurs?

1. 30%

2. 50%

3. 60%

4. 70%

The correct answer is: 60%

The correct answer indicates that approximately 60% of newborns are reported to have murmurs, which is a significant percentage reflecting the normal physiological phenomenon observed in this population. Newborn murmurs are often related to transient conditions resulting from the adaptation of the circulatory system to life outside the womb. The closure of fetal shunts and the transition from placental to pulmonary circulation can lead to innocent murmurs. These murmurs are typically benign and resolve as the newborn matures. Understanding this prevalence is crucial for midwives and healthcare providers. It highlights the need for proper assessment and reassurance, given that most murmurs in newborns do not indicate underlying pathology. Observing this higher incidence helps inform appropriate monitoring and follow-up during routine examinations, ensuring that any concerns can be promptly identified and addressed without unnecessary alarm to parents.
