Medical School MD + DO Mastery

A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

OB/GYN CLERKSHIP - PRENATAL + FETAL ASSESSMENT

YEAR 3 | PAGE 30E - PREGNANCY STATUS -> GESTATIONAL AGE -> MATERNAL / FETAL RISK

WHY OB/GYN REQUIRES SEQUENCE, NOT LIST MEMORIZATION

The same symptom changes meaning with pregnancy status, gestational age, maternal stability and fetal status. Build every obstetric case in order: confirm the pregnancy context, identify threats to the pregnant patient, assess fetal well-being when relevant, then choose the next test or treatment that changes management.

A. THE OBSTETRIC FIRST-PASS FRAME

StepAsk yourselfWhy it matters
1. Pregnancy contextPregnant or potentially pregnant? What gestational age, dating confidence, parity and prior obstetric history?Gestational age changes the differential, test interpretation, medication choices, fetal viability questions and delivery thresholds.
2. Maternal stabilityHemorrhage, severe hypertension, sepsis, cardiopulmonary compromise, severe pain or altered mental status?Maternal stabilization comes first. A reassuring fetal assessment does not override an unstable pregnant patient.
3. Fetal statusWhen applicable: fetal movement, heart-rate pattern, growth, presentation and evidence of placental/uteroplacental disease?Maternal and fetal information must be integrated; the next step may be surveillance, imaging, delivery planning or escalation.
4. Trimester-specific differentialIs this first-trimester bleeding/pain, antepartum complication, labor problem or postpartum disease?OB questions often test whether you apply the correct differential at the correct pregnancy stage.
5. Test that changes managementWhich lab, ultrasound, monitoring or procedure will alter immediate treatment or timing of delivery?Avoid ordering every possible test. Sequence the minimum necessary evaluation around the decision at hand.
6. Shared plan + dispositionObserve, discharge with follow-up, admit, consult, deliver or operate? What are the patient's goals and safety constraints?Consent, preferences, access to follow-up and interprofessional escalation are part of safe obstetric care.

B. PRENATAL + FETAL-ASSESSMENT HIGH-YIELD CHECK

DomainReasoning anchor
Preconception / early pregnancyMedication/teratogen review, chronic disease optimization, folate/nutrition, blood type/Rh context, infection/immunization review and accurate dating.
Routine antepartum careTrend blood pressure, weight, fetal growth and symptoms; know what screening belongs to early pregnancy versus later gestation and use current guidance rather than memorizing outdated intervals.
Genetic / aneuploidy assessmentSeparate screening from diagnostic testing. Interpret the patient's gestational age, risk, goals and the consequences of a positive screen before selecting the next step.
Fetal growth / placentaFundal height or ultrasound discordance should trigger reasoning about dating, growth restriction, macrosomia, fluid abnormalities and placental disease.
Antepartum surveillanceAsk why surveillance is indicated and what an abnormal result would change. NST/BPP/Doppler concepts are management tools, not isolated facts.
Hypertension / diabetesRecognize the pregnancy-specific disease pattern, maternal end-organ risk and fetal/placental consequences; know when worsening maternal or fetal status changes timing of delivery.
