ICU management of hypertensive crisis with acute target-organ damage. Establish an arterial line, lower MAP gradually — not abruptly — and tailor agent and target to the syndrome: aortic dissection, ICH, ischemic stroke, ACS, pulmonary edema, or eclampsia.

Initial ED / inpatient management of adult AMI. For suspected STEMI, activate the cath lab immediately — time is muscle. Give aspirin, load a P2Y₁₂ inhibitor, anticoagulate, and start guideline-directed medical therapy while pursuing reperfusion.

Severity-based repletion of potassium, magnesium, phosphate, and calcium in the critically ill adult, with a high-level framework for sodium disorders. Confirm renal function and access before dosing, replace magnesium alongside refractory hypokalemia, and recheck on schedule

ICU management of HRS in cirrhosis. Confirm the diagnosis by excluding other causes and trialing albumin, then treat with a vasoconstrictor plus albumin while aggressively finding and reversing the precipitant. Engage hepatology, nephrology, and transplant early.

ICU management of adult HHS — fluids first, potassium before insulin, and a slow, controlled correction of osmolality and glucose. Replace a large free-water deficit gradually, treat the precipitant, and watch mental status closely.

ICU management of acute adrenal insufficiency. On clinical suspicion, give stress-dose hydrocortisone immediately, resuscitate with isotonic fluids, and correct hypoglycemia and hyperkalemia — draw cortisol and ACTH but never delay treatment for results.

ICU management of severe, decompensated hypothyroidism. Treat empirically on clinical suspicion — do not wait for confirmatory thyroid studies.

Hyperglycemia management in the critically ill adult. Use subcutaneous correctional insulin for the stable patient and an IV infusion for instability or rapidly fluctuating glucose. Target 140–180 mg/dL, check potassium before insulin, and overlap basal before stopping the drip.

ICU management of adult septic shock. Execute the Hour-1 bundle on recognition — lactate, cultures, antibiotics, fluids, and early vasopressors — then resuscitate to perfusion targets and control the source. Adapt every dose to your institutional protocol and the patient in front of you.

ICU management of suspected or confirmed adult upper GI bleeding — resuscitate first, protect the airway, give a PPI, and cover for varices when cirrhosis is suspected. Restrictive transfusion, early endoscopy, and a clear rebleeding plan drive outcomes.

ICU management of severe, life-threatening thyrotoxicosis. Treat empirically on clinical suspicion — do not wait for confirmatory thyroid studies. Sequence matters: β-blockade and a thionamide first, then iodine, with glucocorticoids early. Adapt every dose to your institutional protocol and the patient in front of you.

Initiate sepsis bundle within 1 hour: measure lactate, obtain blood cultures, administer broad-spectrum antibiotics, give 30 mL/kg IV fluids, and start vasopressors
