There's your complete Module 4 exam guide, pulled directly from Williams Obstetrics. Here's how it's organized to help you study efficiently tonight:
What's Covered:
-
Analgesia & Anesthesia — Systemic opioids (meperidine dosing, naloxone reversal), epidural drugs (bupivacaine vs. chloroprocaine), and the critical exam fact that epidural does NOT increase C-section rate — it only prolongs the second stage by 25 minutes.
-
Vaginal Delivery — The 3 P's (Powers, Passenger, Passage), 7 cardinal movements, and episiotomy.
-
Breech Presentation — Incidence by GA, 3 types, 3 risks (cord prolapse, head trapping, trauma), ECV, and when to do cesarean vs. vaginal.
-
Operative Vaginal Delivery — Full ACOG forceps classification (outlet/low/mid), prerequisites for application, vacuum (Malmström 1954), vacuum vs. forceps comparison, and the critical sequential-use warning (7.4× ICH risk).
-
Cesarean Delivery — History, incidence trends, incision types, indications, maternal complications, antibiotic prophylaxis dosing (2 g vs. 3 g cefazolin by weight), and pelvic floor data.
-
Prior Cesarean/VBAC — Low transverse = TOLAC eligible; classic = mandatory repeat C-section (1–12% rupture risk); induction protocols by gestational age and scar type.
The High-Yield Summary Table and Quick Mnemonics at the end are the fastest review if you're short on time. Good luck on your exam!
