YEAR 3 | PAGE 62D - 10 HIGH-DISCRIMINATION CASES + NBME / COMAT TRANSFER

FINAL REVIEW SHOULD FORCE SEQUENCING: RECOGNIZE INSTABILITY -> DEFINE THE SYNDROME / CHIEF COMPLAINT -> RANK DANGEROUS ALTERNATIVES -> CHOOSE THE NEXT TEST OR PROCEDURE -> TREAT -> REASSESS -> SOURCE CONTROL / DISPOSITION. G. 10 HIGH-DISCRIMINATION SHELF / COMAT CASES

#	Case pattern	Best exam reasoning
1	Post-op day 1 tachycardia + falling BP + increasing drain blood.	Treat as hemorrhagic instability: resuscitate and escalate to hemorrhage/source control; do not begin with a low-yield broad fever workup.
2	Post-op oliguria after major surgery; hypotension and rising creatinine.	Assess perfusion/volume, catheter patency and trajectory; fluid is a hypothesis to test, not an automatic reflex.
3	Diffuse abdominal pain + rigidity + free air.	Perforation/peritonitis: resuscitation + antibiotics + urgent source control outrank further diagnostic refinement.
4	Blunt trauma, hypotension, positive FAST.	Instability + localizable intra-abdominal bleeding: move toward definitive hemorrhage control rather than routine CT.
5	Small-bowel obstruction with fever, tachycardia, focal tenderness and metabolic concern.	Recognize strangulation/ischemia risk; uncomplicated-obstruction algorithms no longer apply.
6	Chest pain + diaphoresis + ischemic ECG changes.	Stabilize and activate the urgent ACS/reperfusion pathway; do not delay with lower-yield confirmatory testing.
7	Dyspnea + unilateral absent breath sounds + shock after trauma.	Treat a tension physiology clinically when present; confirmatory imaging must not delay decompression.
8	AMS + bradypnea after opioid exposure.	Ventilation/airway is the immediate threat; reverse clinically important opioid effect and reassess for recurrence.
9	Overdose + hypotension + wide QRS.	Think sodium-channel blockade: ECG drives urgency and targeted antidotal/supportive treatment.
10	Pain improved after ED treatment but serial evaluation still shows unresolved high-risk disease.	Disposition follows residual risk and trajectory, not symptom improvement alone; observation/admission may be the correct next step.

H. CURRENT OFFICIAL COVERAGE / READINESS ANCHORS

Assessment signal	Current official anchor	How to use it
COMAT Surgery	GI/Nutrition 18-24%; Perioperative Care 16-20%; Hepato/Biliary 14-20%; Trauma 14-18%. H&P;/Diagnosis, Diagnostic Technologies and Management are each 25-35%.	Protect the high-weight surgery domains but keep breast, hernia, endocrine and MSK/integument active.
COMAT Emergency Medicine	GI 11-14%; cardiovascular 11-14%; trauma 9-12%; neuro/mental 8-12%; GU/renal/breast 8-12%; respiratory 8-11%; tox/environment 5-8%.	Practice chief-complaint algorithms, rapid stabilization, diagnostic technologies, management and disposition.
NBME Clinical Science Mastery Series	Surgery and Emergency Medicine are included; each CSMS form has 50 MCQs. Standard-paced format: 75 minutes.	Use timed forms late in the rotation; classify misses by content + sequencing error, then remediate recurrent patterns.
COMAT Clinical format	Each COMAT Clinical subject exam contains 120 items in 2.5 hours and integrates OPP/OMM into the discipline blueprint.	DO learners should practice COMAT-style pacing and add OPP/OMM only when clinically appropriate - never at the expense of urgent stabilization.

H. CURRENT OFFICIAL COVERAGE / READINESS ANCHORS — SURGERY + EMERGENCY MEDICINE MASTERY GATE

You are ready to move on when you can identify instability before naming the disease, decide when imaging is appropriate versus dangerous delay, choose the correct intervention class and timing, recognize trauma/toxicology emergencies, reassess response, and defend disposition or source-control decisions on new mixed cases.
