Inpatient Obstetric Nurse Practice Exam 2025 – Complete Prep Guide

The percentage of newborns reported to have a major anomaly falls within the range of 1-2%. This figure is derived from extensive epidemiological studies that have tracked congenital anomalies over time. Major anomalies, also known as major congenital disorders, are significant structural or functional abnormalities that are present at birth and can affect various systems in the body.

Research indicates that the prevalence of major congenital defects in live births is typically around 2-3%, with some studies suggesting slightly lower figures in certain populations. Therefore, the range of 1-2% is a widely accepted estimate in clinical practice and epidemiological reporting, reflecting the proportion of newborns affected by serious and detectable anomalies that often necessitate medical intervention or surgical repair.

The higher percentages suggested in some of the other options are not supported by the current understanding of population-level data regarding major congenital anomalies. This emphasizes the importance of accurate statistical data in the field of obstetrics and pediatrics as well as the need for continuous monitoring and research to better understand the implications of these birth defects on public health.
