What guideline should a nurse provide regarding alcohol consumption in pregnancy?

The guideline that advises to avoid all alcohol during pregnancy is based on extensive research indicating that there is no known safe level of alcohol consumption during this time. Alcohol can cross the placenta and affect fetal development, potentially leading to a range of disorders categorized as fetal alcohol spectrum disorders (FASDs), which can cause lifelong physical, behavioral, and cognitive impairments.

The recommendation to avoid all alcohol is supported by numerous health organizations, including the Centers for Disease Control and Prevention (CDC) and the American College of Obstetricians and Gynecologists (ACOG), emphasizing the importance of safeguarding fetal health. Since the effects of alcohol on the developing fetus can occur at any stage of pregnancy, the safest approach is complete abstinence.

Given that the other options suggest varying degrees of alcohol consumption, they do not align with the current understanding of the risks associated with alcohol during pregnancy. Hence, the guideline of total avoidance is crucial for protecting fetal health.
