Macrosomia is associated with birth asphyxia and trauma. Which statement describes this?

• A. Macrosomia is associated with birth asphyxia and trauma.
• B. Macrosomia is not associated with any complications.
• C. Macrosomia always results in preterm labor.
• D. Macrosomia is defined by a birth weight under 2500 g.

Answer: (A)

Macrosomia refers to a larger-than-average fetus, typically defined by a birth weight around 4000 g or more. This extra size makes delivery more challenging, especially through the birth canal, increasing the risk of shoulder dystocia and other birth injuries, and it can lead to temporary or prolonged oxygen deprivation for the baby during labor. Because of these mechanical and hypoxic risks, macrosomia is indeed associated with birth asphyxia and trauma, which is why the statement describing this association is the best choice.

Other options don’t fit because macrosomia does come with complications, it doesn’t necessarily imply preterm labor (many macrosomic babies are born at term or post-term), and it is defined by a high birth weight—not by a weight under 2500 g.
