Mean arterial pressure (MAP) is equal to correct answers [(2x DBP) + SBP] divided by 3. (Hypertensive
Crisis Scenario)
2. Preload is volume measured by correct answers CVP (right atrial pressure), Afterload is pressure
measured by SVR (systemic vascular resistance).
Afterload is low correct answers only in distributive shock.
Volume increases correct answers preload, diuretics (Lasix) decrease preload.
NTG and Nipride correct answers decrease afterload.
Vasopressors correct answers increase afterload.
3. Vasopressor extravasation - correct answers Phentolamine (Regitine).
5. Treatment of Ventricular Tachycardia - correct answers If pulse, but unstable - synchronize
cardioversion on R wave (Peds wattage 05-1 j/kg). If stable - Adenosine for monomorphic, then choice of
Amiodarone, Sotalol, or Procainamide. If pulseless VT- BLS and defibrillation at 120-200 joules (Peds start
at 2-4 j/kg).
6. Cardiac arrest - correct answers Get ETCO2 > 10 in quality BLS. Point of care ultrasound (POCUS) to
assess H & T's
7. Symptomatic bradycardia - correct answers Try atropine 0.5 mg, then try transcutaneous pacing - set
rate at 60-80 & turn up milliamps until capture (Do not assess carotid pulse). Next, Dopamine or
Epinephrine infusion.
8. No Atropine needed for correct answers transplanted heart, treat with Isoproterenol (Isuprel) instead.
9. Wolff-Parkinson-White (WPW) correct answers is an accessory pathway disorder - Delta wave = short
PR interval, wide QRS on upstroke of QRS, WPW risk - tachycardia.
10. R on T phenomenon (PVC) occurs when correct answers an electrical impulse (R) is to too close to
the resting phase of the ventricle (T), leading to ventricular tachycardia or ventricular fibrillation.
11. Prolonged QTi can be from medication (Erythromycin, Haldol, TCA's, etc.) or
hypomagnesemia/hypocalcemia. (Not all-inclusive list) correct answers
Assess EKG for T wave inversion for ischemia, ST segment elevation for injury (STEMI). correct answers
13. ST segment elevation in leads II, III, AVF - correct answers Inferior MI (right coronary artery);
V1-V4 - correct answers Anterior MI (LAD artery);
