Answer-Top 5 MCQs on Obstetrics

1. Answer: 

C) Oxytocin


  • Oxytocin is the hormone responsible for stimulating uterine contractions during labor.

  • Produced by the hypothalamus and released by the posterior pituitary gland, oxytocin plays a crucial role in initiating and regulating the rhythmic contractions of the uterus. 

  • These contractions are essential for the progression of labor and the eventual birth of the baby. 

  • Oxytocin also plays a significant role in promoting bonding between the mother and her baby, as it is released during breastfeeding and skin-to-skin contact.

2. Answer: 

C) 40 weeks


  • A full-term pregnancy typically lasts around 40 weeks, calculated from the first day of the last menstrual period (LMP). 

  • However, it's important to note that a normal pregnancy duration can range from 37 to 42 weeks. 

  • Babies born between 37 and 42 weeks are considered full-term and have the best chances of healthy development. 

  • Babies born before 37 weeks are considered preterm, while those born after 42 weeks are considered post-term.

3. Answer: 

B) Breech presentation


  • Breech presentation occurs when the baby's buttocks or feet are positioned to enter the birth canal first, instead of the head. 

  • This presentation is considered less favorable for vaginal delivery due to the increased risk of complications, such as cord prolapse or head entrapment. 

  • Different types of breech presentations include complete breech (both knees and hips flexed), frank breech (hips flexed with knees extended), and footling breech (one or both feet presenting first).

  • Vaginal delivery for breech presentation requires careful assessment and skilled obstetric care.

4. Answer: 

B) Second stage


  • The second stage of labor begins after complete cervical dilation and is characterized by the actual birth of the baby. 

  • During this stage, the mother experiences strong urges to push as the baby's head descends through the birth canal and crowns. 

  • This stage can last from a few minutes to a couple of hours. Adequate maternal effort, positioning, and effective coaching are crucial to facilitate a safe and successful delivery. 

  • Following the birth of the baby, the third stage involves the delivery of the placenta.

5. Answer: 

C) To evaluate the baby's physical condition and overall well-being


  • The Apgar score is a quick assessment tool used to evaluate the newborn's physical condition immediately after birth. It assesses five vital signs: heart rate, respiratory effort, muscle tone, reflexes, and skin color. 

  • Each parameter is scored on a scale from 0 to 2, and the scores are summed to provide an overall Apgar score. 

  • This score helps healthcare providers quickly identify any potential issues that might require immediate intervention.
  • The Apgar score is usually taken at 1 and 5 minutes after birth. It's important to note that a low Apgar score at 1 minute doesn't necessarily predict long-term outcomes; it's the trend over the first few minutes that is more important in determining the baby's well-being.
