Clinical Management

A Step 2 CK–focused management lesson on sepsis and septic shock built around the Surviving Sepsis Campaign Hour-1 bundle: cultures before antibiotics, broad-spectrum antibiotics within an hour, 30 mL/kg crystalloid, and norepinephrine-first vasopressor escalation (vasopressin second, epinephrine third) to MAP ≥65, with source control, hydrocortisone for vasopressor-dependent refractory shock, and the classic distractors emphasized.

A Step 2 CK management lesson on diabetic ketoacidosis built around the ordered algorithm — fluids first, potassium before insulin, insulin drip continued with dextrose until the anion gap closes — with two \"next best step\" vignettes and the classic pitfalls (hypokalemia, stopping insulin too early, cerebral edema, euglycemic DKA).

A management-focused Step 2 CK review of anticoagulation: choosing the agent by indication (DOAC vs warfarin vs heparin), reversing life-threatening bleeds, managing suspected HIT, and deciding when peri-procedural and initiation bridging are — and are not — needed.

A Step 2 CK management lesson on fluid and electrolyte emergencies, framed around volume status, symptom severity, and safe correction rate — covering the hyperkalemia stabilize-shift-eliminate algorithm, hyponatremia treatment by volume status with hypertonic-saline rescue, and the correction-rate pitfalls (osmotic demyelination, cerebral edema) that drive the "next best step" answer.

A Step 2 CK-focused walkthrough of acute GI bleeding management: resuscitate before you investigate, risk-stratify, give the right pre-endoscopy pharmacology (IV PPI for ulcers; octreotide + ceftriaxone for varices), transfuse restrictively, and know exactly when to escalate to endoscopy, IR, or surgery.

A Step 2 CK management lesson on perioperative risk assessment for non-cardiac surgery: the ACC/AHA stepwise algorithm, RCRI scoring, the ≥4-MET functional-capacity rule that stops most workups, and evidence-based perioperative medication management (beta-blockers, DAPT/stent timing, anticoagulation bridging, SGLT2/metformin, steroids). Emphasis throughout is the \"next best step\" — optimize and proceed, and test only when it changes management.

A Step 2 CK–focused, algorithm-first guide to managing acute asthma and COPD exacerbations — first-line therapy, ordered escalation, and the oxygen, antibiotic, and ventilation decisions that distinguish the two. Emphasizes the "next best step in management" and impending-respiratory-failure red flags.

A management-focused Step 2 CK lesson separating hypertensive emergency (severe BP plus acute target-organ damage → ICU, IV titratable agents, controlled reduction of SBP by ≤25% in the first hour) from urgency (no organ damage → oral meds, gradual outpatient lowering over 24–72 h), with condition-specific first-line agents, organ-specific BP targets, and the classic \"next best step\" pitfalls.
