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.

DETERIORATION + RAPID RESPONSE + CRITICAL CARE

YEAR 4 | PAGE 34B - RECOGNIZE -> RESUSCITATE -> REASSESS -> ESCALATE

CORE RULE A deteriorating patient changes the sequence. Stabilization and escalation take priority over completing a beautiful differential. Use a structured primary survey, treat immediate threats as they are found, re-assess after each intervention, and follow local rapid-response/resuscitation protocols.

D. THE FIRST FIVE MINUTES

StepActionWhat “good” looks like
1. Recognize + callNotice abnormal trend, mental-status change, work of breathing, hypotension, chest pain, oliguria, bleeding or staff concern. Get senior/rapid-response help early.Help is mobilized before the patient is peri-arrest.
2. ABCDE + monitoringAirway, breathing, circulation, disability, exposure; attach monitoring and obtain focused bedside data.Life threats and trajectory are identified systematically.
3. Treat threats nowCorrect immediately reversible problems within supervision/protocol: oxygenation/ventilation, hemorrhage, severe hypoglycemia, anaphylaxis, etc.Therapy is not delayed for nonessential diagnostics.
4. Focused diagnosticsSelect tests that change the next action: ECG, blood gas, labs, bedside ultrasound, urgent imaging/cultures when appropriate.Each test has a decision consequence.
5. Reassess + communicateRepeat the primary survey, interpret response, update working diagnosis, communicate using structured handoff.The team knows whether the patient is improving, unchanged or worsening.

E. SHOCK AS A YEAR 4 INTEGRATION PROBLEM

PatternClues to integrateImmediate priorities to understand
Hypovolemic / hemorrhagicVolume loss, bleeding, low preload, cool extremities, narrow pulse pressure depending on stage.Control source, restore circulating volume/blood per protocol, reassess perfusion and response.
Distributive / septicVasodilation, infection/inflammation context, warm or cool shock depending on phase, lactate/organ dysfunction.Early recognition, source evaluation/control, antimicrobials and hemodynamic support per local protocol.
CardiogenicPulmonary edema, ischemia/arrhythmia/structural disease, congestion, poor forward flow.ECG/echo-oriented reasoning, cautious fluid decisions, targeted hemodynamic support and specialist escalation.
ObstructiveTamponade, tension pneumothorax, massive PE or other mechanical block to filling/outflow.Recognize the obstructive cause and obtain urgent definitive relief/escalation.

F. RESPIRATORY FAILURE + VENTILATOR PRIMER

  • Separate oxygenation from ventilation: hypoxemia is not the same problem as hypercapnia or ventilatory fatigue.
  • Before intubation: understand indication, preoxygenation, predicted difficult airway, hemodynamic risk and rescue plan; observe/assist only within your level of training.
  • After intubation: know what FiO2, PEEP, tidal volume, respiratory rate and pressure alarms are changing; connect them to ABG/SpO2, mechanics and the patient’s disease.
  • Always reassess the whole patient: sudden deterioration on a ventilator can be airway/tube, pneumothorax, secretions, equipment, hemodynamics or disease progression.
