Induction of labour is indicated in all of the following except
**Core Concept**
Induction of labor is a medical intervention aimed at initiating contractions to facilitate vaginal delivery, typically in the presence of a favorable cervix. The decision to induce labor is guided by clinical guidelines and involves assessing the risks and benefits of proceeding with labor against the potential risks of continuing the pregnancy.
**Why the Correct Answer is Right**
The management of postdated pregnancy (beyond 42 weeks of gestation) is a common indication for labor induction. At this gestational age, the risks of continuing the pregnancy, such as fetal growth restriction and increased risk of stillbirth, outweigh the benefits of waiting for spontaneous labor. Induction of labor is often performed using oxytocin or misoprostol to stimulate uterine contractions.
**Why Each Wrong Option is Incorrect**
**Option A:** Although fetal distress is a potential indication for immediate delivery, it is not typically an indication for labor induction. Instead, delivery is usually expedited through cesarean section or instrumental vaginal delivery.
**Option B:** Multiple gestations (twins, triplets, etc.) are a relative contraindication to induction of labor due to the increased risk of complications, such as umbilical cord prolapse and fetal distress. However, this option is not the correct answer.
**Option C:** Fetal macrosomia (excessive fetal growth) is a relative contraindication to induction of labor due to the increased risk of complications during delivery. However, this option is not the correct answer.
**Clinical Pearl / High-Yield Fact**
A key aspect to remember when considering induction of labor is the Bishop score, which assesses the likelihood of successful induction based on cervical dilation, effacement, consistency, position, and fetal station. A higher Bishop score indicates a more favorable cervix and a greater likelihood of successful induction.
**Correct Answer:** D.
