Norepinephrine infusion via central line, targeting mean arterial pressure at least 65 mmHg.

ECG Leads for Lateral Wall MI

Leads I, aVL, V5, V6 (supplied by the Left Circumflex - LCx artery).

Anaphylaxis First-Line Agent

Intramuscular epinephrine (1:1,000) administered into the anterolateral mid-thigh.

Gold Standard Biomarker for Acute MI

Cardiac Troponin I or T (rises within 3-4 hours, peaks at 24h, remains elevated 7-14 days).

CURB-65 Criteria

Confusion, Urea > 7 mmol/L, Respiratory rate >= 30, Blood pressure < 90/60, Age >= 65.

ECG Hallmark of Hyperkalemia

Tall, symmetrical peaked T waves, prolonged PR interval, widening QRS, progressing to sine wave.

CHA2DS2-VASc Score

Clinical risk tool calculating thromboembolic stroke risk in non-valvular atrial fibrillation.

Treatment Steps for Severe Hyperkalemia

1. IV Calcium gluconate (cardioprotection)
2. IV Regular insulin + 50% Dextrose (intracellular shift)
3. Salbutamol nebulization
4. Hemodialysis/resin.

Metformin eGFR Contraindication

Contraindicated when eGFR falls below 30 mL/min/1.73 m² due to lactic acidosis risk.

First-Line Oral Agent for Type 2 Diabetes

Metformin (Biguanide): decreases hepatic gluconeogenesis; contraindicated in severe eGFR

< 30

Potassium Chloride IV Warning

Prohibited as direct IV push; must be diluted in solution and infused at a controlled rate.

Diagnostic Criteria for Diabetes Mellitus

Fasting Plasma Glucose

\geq 126 mg/dL

(7.0 mmol/L) OR

H b A 1 c \geq 6.5%

OR 2h OGTT

\geq 200 mg/dL

Status Epilepticus First-Line

Intravenous lorazepam or intramuscular midazolam administered promptly upon presentation.

Emergency Thrombolysis Window in Ischemic Stroke

IV Alteplase (r-tPA) administered within 4.5 hours of symptom onset (after excluding hemorrhage via non-contrast CT).

Tension Pneumothorax Management

Immediate needle thoracostomy decompression, followed promptly by tube thoracostomy.

Most Common Organism in Community-Acquired Pneumonia

*Streptococcus pneumoniae* (Pneumococcus).

Amiodarone Monitoring Parameters

Baseline and serial thyroid function, liver function, and pulmonary function testing.

Hospital-Acquired Pneumonia (HAP) Common Organisms

*Pseudomonas aeruginosa and Methicillin-Resistant Staphylococcus aureus* (MRSA).

Glasgow Coma Scale Range

Scored from 3 (deep unresponsive coma) to 15 (fully alert and oriented patient).

Primary Spontaneous Pneumothorax Presentation

Sudden pleuritic chest pain and dyspnea in tall, slender young males; decreased breath sounds and hyperresonance.

Hypoglycemia Rule of 15

Administer 15 grams fast-acting carbohydrates and re-evaluate capillary glucose in 15 minutes.

Tension Pneumothorax Emergency Treatment

Immediate needle decompression (2nd intercostal space midclavicular line or 4th/5th anterior axillary line), followed by chest tube.

Digoxin Toxicity Classical ECG Sign

Sagging ST-segment depression resembling a scoop, with PR interval prolongation.

Diagnostic Triad of Meningitis

Fever, altered mental status, and nuchal rigidity (neck stiffness).

Warfarin Reversal Agents

Vitamin K (phytomenadione) and four-factor prothrombin complex concentrate.

CSF Findings in Bacterial Meningitis

Marked neutrophil pleocytosis, low glucose (

< 40%

serum), high protein (

> 100 mg/dL

), elevated opening pressure.

Heparin Reversal Agent

Protamine sulfate, neutralizing unfractionated heparin at 1 mg per 100 units.

WHO Surgical Safety Checklist Phases

1. Sign In (before anesthesia)
2. Time Out (before skin incision)
3. Sign Out (before patient leaves operating room).

Cardiac Troponin Specificity

Highly sensitive and specific serum biomarker detecting myocardial cellular necrosis.

Definition of Sentinel Event

An unexpected occurrence involving death or serious physical/psychological injury requiring immediate investigation.

Acute Pancreatitis Diagnosis Criteria

Requires 2 of 3: epigastric pain, serum lipase or amylase > 3x upper limit, or imaging findings.

Colorectal Cancer Screening Recommendation

Colonoscopy every 10 years starting at age 45-50 for average-risk asymptomatic adults.

Diabetic Ketoacidosis Triad

Hyperglycemia, high anion gap metabolic acidosis, and confirmed serum or urine ketones.

Sensitivity of a Screening Test

Ability to correctly identify those with the disease:

\frac{TP}{TP + FN}

(low false negatives).

Cushing Triad of Elevated ICP

Progressive hypertension with widening pulse pressure, bradycardia, and irregular respirations.

Specificity of a Diagnostic Test

Ability to correctly identify those without the disease:

\frac{TN}{TN + FP}

(low false positives).

Adult CPR Compression Rate

100 to 120 chest compressions per minute at a depth of 5 to 6 cm (2 to 2.4 inches).

Vaccine Cold-Chain Temperature Standard

Strict storage between **

+ 2^{\circ} C

and

+ 8^{\circ} C

**.

Beck Triad of Cardiac Tamponade

Hypotension, distended jugular veins, and muffled or distant heart sounds.

Anaphylaxis Epinephrine Dose in Adults

0.3 to 0.5 mg of 1:1000 IM into the vastus lateralis.

Opioid Overdose Antidote

Naloxone, administered via intravenous, intramuscular, subcutaneous, or intranasal routes.

Brudzinski and Kernig Signs

Brudzinski: neck flexion causes involuntary hip/knee flexion; Kernig: resistance to passive knee extension at
