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.

SCHOOL-EXAM + PROBLEM-SOLVING MASTERY

YEAR 2 | PAGE 25G - DIAGNOSTICS, ANTIMICROBIAL LOGIC + PREVENTION

C. WHAT SCHOOL EXAMS COMMONLY REQUIRE

ResourceDescriptionLink
Syndrome localizationPneumonia, meningitis/encephalitis, UTI, endocarditis, skin/soft-tissue, GI infection, STI and fever without a clear source.
Host + exposureAge, pregnancy, immune status, devices, hospital exposure, travel, animals/food/water, sexual exposure and vaccination history.
Specimen + diagnosticsBlood/urine/CSF/sputum/wound samples; Gram stain/culture; NAAT/PCR; antigen/serology; imaging; test timing before antibiotics when safe.
Empiric -> definitiveCover dangerous likely pathogens first, then narrow to culture/susceptibility or molecular result; account for site penetration and allergies.
Resistance + stewardshipBeta-lactamases, altered targets, efflux/permeability and biofilm; antibiogram logic; source control; de-escalation and duration principles.
HIV + opportunistic infectionHIV testing/viral load/CD4 logic; common OIs by immune status; ART classes/interactions; prophylaxis and immune-reconstitution concepts.
Vaccines + infection controlStandard precautions plus contact/droplet/airborne isolation; vaccine-preventable disease; exposure/post-exposure concepts and reporting.
Sepsis + public healthRecognize unstable infection, source control and cultures without delaying urgent care; know outbreak, exposure and prevention reasoning.

D. 7-DAY SCHOOL-EXAM REVIEW CYCLE

ResourceDescriptionLink
Days 1-2Respiratory/CNS/urinary/cardiac syndromes. Build pathogen lists from site + host + exposure, then choose the first diagnostic test.
Days 3-4Antibiotics + resistance. Match syndrome to empiric coverage; practice narrowing from cultures, susceptibility and patient factors.
Day 5HIV/OIs, TB, fungi, viruses, STIs and C. difficile. Use immune status, transmission and prevention to separate look-alikes.
Day 6Vaccines/isolation/stewardship + mixed timed block. Force yourself to state why each wrong option fails by site, test or spectrum.
Day 7Re-test every miss on new cases; rewrite only the recurring organism-drug-test associations that remain unstable.

SITE/SYNDROME - localization | HOST/EXPOSURE - risk factor | PATHOGEN - organism class | TEST - specimen/assay/timing | SPECTRUM - coverage | RESISTANCE - mechanism | TOXICITY/INTERACTION - drug safety | HIV/OI - immune-status | ISOLATION/PREVENTION - transmission | URGENCY - empiric therapy/source control

D. 7-DAY SCHOOL-EXAM REVIEW CYCLE — SCHOOL-EXAM MASTERY GATE

Proceed when you can move from syndrome + host -> likely pathogen -> test -> empiric coverage -> narrowed therapy -> isolation/prevention, and explain why competing organisms or drugs fail. VIDEO-FIRST | SCHOOL-EXAM + BOARD-EXAM MASTERY
