Here are 20 multiple-choice questions based on the provided slides about "Versions in Labour": 1. What is the primary definition of "Versions in Labour"? A) Surgical procedures to remove the fetus. B) Obstetric manoeuvres performed to change the fetal position or presentation during labour. C) Medical induction of labour. D) Techniques to monitor fetal heart rate. Correct: B 2. The main aim of performing versions in labour is to: A) Reduce maternal pain during delivery. B) Facilitate safe vaginal delivery when malpresentation occurs. C) Shorten the duration of labour. D) Prevent the need for any medical intervention. Correct: B 3. Which type of version involves turning the fetus from a breech or transverse lie to a cephalic presentation by abdominal manipulation? A) Internal Podalic Version (IPV) B) Combined Version C) External Cephalic Version (ECV) D) Manual Rotation Correct: C 4. Internal Podalic Version (IPV) is characterized by: A) Abdominal manipulation only. B) Introducing a hand into the uterus to turn a fetus to breech for extraction. C) Using both internal and external manoeuvres. D) Administering medication to change fetal position. Correct: B 5. A patient at 37 weeks gestation presents with a breech lie. Which version procedure is primarily indicated? A) Internal Podalic Version (IPV) B) External Cephalic Version (ECV) C) Combined Version D) Forceps delivery Correct: B 6. Which of the following is a contraindication for External Cephalic Version (ECV)? A) Breech lie at 36 weeks B) Multiparity C) Placenta previa D) Adequate amniotic fluid Correct: C 7. The procedure for External Cephalic Version (ECV) primarily involves: A) Inserting a hand into the uterus to grasp the fetal feet. B) Abdominal manipulation to rotate the fetus to a cephalic position. C) Using vacuum extraction to guide the fetal head. D) Administering oxytocin to stimulate contractions. Correct: B 8. Internal Podalic Version (IPV) is indicated in which of the following scenarios? A) Breech lie at 38 weeks B) Second twin in transverse lie C) Fetal compromise with a cephalic presentation D) Major placenta previa Correct: B 9. A patient with a scarred uterus (e.g., from a previous Cesarean section) is being considered for a version. Which type of version is specifically contraindicated in this case? A) External Cephalic Version (ECV) B) Internal Podalic Version (IPV) C) Combined Version D) Both B and C Correct: B 10. Which of the following is a potential risk or complication associated with versions in labour? A) Hypertension B) Uterine rupture C) Gestational diabetes D) Pre-eclampsia Correct: B 11.

In which situation should a version generally NOT be attempted? A) Unengaged presenting part B) Multiparity C) Severe fetal compromise D) Breech lie at term Correct: C 13. Before attempting a version, what is a crucial step in clinical decision-making? A) Immediate induction of labour B) Preparing for an elective Cesarean section C) Obtaining informed consent D) Administering general anesthesia Correct: C 14. External Cephalic Version (ECV) is generally contraindicated in multiple pregnancies, with one specific exception. What is that exception? A) Triplets B) Quadruplets C) Second twin D) Any multiple pregnancy is an absolute contraindication Correct: C 15. The procedure for Internal Podalic Version (IPV) involves grasping which part of the fetus for extraction? A) Head B) Shoulders C) Feet D) Buttocks Correct: C 16. A "Combined Version" refers to the use of: A) Two different types of anesthesia. B) Both internal and external manoeuvres to correct presentation.
