Inpatient Obstetric Nurse (NCC) Practice Exam

An elevated alpha-fetoprotein (AFP) level is significant in prenatal care as it often indicates potential fetal neural tube defects, such as spina bifida or anencephaly, as well as abdominal wall defects like omphalocele or gastroschisis. AFP is a protein produced by the fetal liver, and its levels are typically measured in maternal blood around the second trimester.

When AFP levels are higher than the expected range for gestational age, healthcare providers may suspect these conditions and may recommend further diagnostic testing, such as an ultrasound or amniocentesis, to assess for specific defects or confirm a diagnosis. Monitoring AFP levels is an essential part of screening for congenital anomalies during pregnancy, enabling timely interventions and support for families if needed.

While normal fetal development would correlate with typical AFP levels, an elevated result is a clear indicator to investigate potential underlying issues. Elevated AFP is not directly associated with an increased risk of preterm labor or maternal liver dysfunction, making the second option the most relevant and accurate interpretation of elevated AFP levels.
