OBGYN COMAT High-Yield Review – 120 Questions – Preeclampsia, Ectopic Pregnancy, Infections, Contraception Q&A 2026

This document is a high-yield OBGYN COMAT review containing approximately 120 concise clinical questions and answers focused on essential obstetrics and gynecology concepts. It covers core topics such as abnormal uterine bleeding, contraception, pregnancy complications, sexually transmitted infections, and gynecologic conditions. Early sections (pages 1–3) emphasize foundational topics like endometrial ablation, secondary amenorrhea evaluation, adnexal mass management, and stress urinary incontinence, while later sections expand into high-yield exam topics including preeclampsia prevention, ectopic pregnancy management, PROM complications, and infectious disease treatment protocols. The document is structured for rapid review and exam preparation, integrating key diagnostic steps, first-line treatments, and clinical decision-making algorithms. It highlights important concepts such as screening timelines (e.g., gestational diabetes at 24–28 weeks), management of vaginal infections (e.g., Candida, bacterial vaginosis, trichomoniasis), and obstetric emergencies like placental abruption and chorioamnionitis. Additionally, it reinforces pharmacologic management including methotrexate for ectopic pregnancy, magnesium sulfate for seizure prevention in eclampsia, and antibiotic regimens for STIs in pregnancy. The concise Q&A format supports active recall and retention, making it ideal for last-minute revision. This resource is highly relevant for courses such as Obstetrics and Gynecology Clerkship, Women’s Health, Reproductive Medicine, and Clinical Medicine. It is ideal for osteopathic medical students preparing for the NBOME OBGYN COMAT exam, as well as students preparing for COMLEX Level 2-CE and USMLE Step 2 CK. It is also suitable for physician assistant (PA) students, nursing students, and international medical graduates seeking a focused and efficient review of OBGYN topics. The content aligns closely with widely used board preparation textbooks such as First Aid for the USMLE Step 2 CK, Case Files Obstetrics and Gynecology, and Blueprints Obstetrics & Gynecology, making it a valuable supplementary resource for reinforcing high-yield knowledge and improving exam performance.
