Quizplus · Accepted Answer

The presence of phosphatidyl glycerol is of particular concern prior to inducing labor in this diabetic woman because it indicates adequate fetal lung maturity. In the Liley graph, zone 2 indicates fetal lung immaturity, which increases the risk of respiratory distress syndrome (RDS) in the newborn. Therefore, confirming fetal lung maturity is crucial before inducing labor. Lecithin, sphingomyelin, and acetylcholinesterase are other phospholipids and enzymes that are used to assess fetal lung maturity, but phosphatidyl glycerol is the most specific and sensitive indicator.
