ESO EKG Sharp Latest Update 2024 -2025 300 120 Questions and 100% Verified Correct Answers Guaranteed A+ 1st degree block - CORRECT ANSWER: PR interval is >.20 but consistent 2nd degree block type 1 (Wenckebach) - CORRECT ANSWER: progressively longer PRI and after 3 it keeps P drops QRS, then repeats pattern. 2nd degree Type 2 - CORRECT ANSWER: Consistent P wave before QRS, but then random other P waves that doesn't coordinate with anything. 2nd degree type 2 - CORRECT ANSWER: PRI consistent but some QRS's not conducted. AMI can turn into CHB. 3rd degree - CORRECT ANSWER: Atrial and Ventrical both 3rd degree block - CORRECT ANSWER: Independent and extra P waves, and QRS complex. P & V is regular (irregular 2nd type 1). A Fib - CORRECT ANSWER: waving deflections on entire baseline Accelerated IVR - CORRECT ANSWER: 50-100. No P, QRS>.12. Looks like a chair. Accelerated Junctional Rhythm - CORRECT ANSWER: 60-100. P wave may be inverted and before/after/hidden in QRS. PRI=<.10 Amiodarone - CORRECT ANSWER: 1. Main Actions: Effects sodium, potassium, and calcium channels as well as having alpha and beta - adrenergic blocking properties. Indications: ventricular rate control in rapid atrial rhythms in patients with severe LV dysfunction, acts as an adjunct to cardioversion of wide complex tachycardia, and pharmacological cardioversion of atrial fibrillation 2. Standing Order: Ventricular Fibrillation/ Pulseless V -tach 3. Considerations: Will produce hypotension and/or bradycar dia when given too quickly. If side effects occur, fluids, pressors, chronotropic agents or temporary pacing may be useful ASA (aspirin) - CORRECT ANSWER: 1. Main Actions: Early administration of ASA has been associated with decreased mortality rates in several clinical trials. It produces a rapid antiplatelet effect with near total inhibition of thromboxane A2 production. It reduces coronary reocclusion and recurrent ischemic events after fibrinolytic therapy. 2. Standing Order: Chest pain 3. Considerations: Aspirin suppositories are safe and may be safely given to patients with severe GI disorders, vomiting, or nausea. Best to chew ASA Asystole Rhythm - CORRECT ANSWER: the absence of ventricular activity, "flat line". Confirmed in at least two different leads, check leads. CPR immediately for 2 min (100 -120). DO NOT DEFIB Atria Flutter - CORRECT ANSWER: 250-400 Atrial rate looks like sawtooth (can be one sawtooth per QRS). Usually normal V rate and QRS<.10 Atropine - CORRECT ANSWER: Anticholinergic. 1. Main Actions: Reverses cholinergic - mediated decreases in heart rate, and will increase the rate of the sinus node, so it is useful in the treatment of symptomatic bradycardia. 2. Standing Order: Bradycardia -
Unstable 3. Considerations: May cause tachycardia, angina. Use cautiously in presence of acute MI, myocardial ischemia. BBB - CORRECT ANSWER: normal with wide QRS Cardioconversion Joules range - CORRECT ANSWER: 75-120-150-200 Cardioversion monitor steps - CORRECT ANSWER: 1) set to defib 2) hit Sync On/Off soft key. 3) adjust joules to start at 75. 4) No analyze, go straight to Charge. 5) click "Shock" until shock delivered. Defib Joules Range - CORRECT ANSWER: 120-150-200 Diphenhydramine (Benadryl) - CORRECT ANSWER: 1. Main Actions: Antihistamine effect 2. Standing Order: Severe Anaphylaxis 3. Considerations: Half life prolonged with age, normally 4 -8hrs, decreases mental alertness and psychomotor performance, increases intraocular pressure, caution with hyperthyroidi sm, bronchial asthma, CV disease, hypertension. May cause sloughing of tissue at infusion site Dopamine - CORRECT ANSWER: 1. Main Actions: A catecholamine that stimulates alpha and beta adrenergic receptors. The effects are dose related. Doses of 0.5 -
3mcg/kg/min produce renal vasodilation Doses of 2 -10mcg/kg/min increase cardiac contractility Doses of 10 -20mcg/kg/min produce vasoconstriction. **Note: On PCU level of care, the max drip dose is 5 mcg/kg/min. Unless the patient requires ICU emergent transfer, then the dose may use up to 20 mcg/kg/min 2. Standing Order: Hypotension -
symptomatic Bradycardia - when Atropine ineffectiv e 3. Considerations: **Indicated for hypotension after fluid resuscitation. Dose is titrated to achieve hemodynamic effect. Increases MV02 without compensatory increases in coronary blood flow causing an imbalance between 02 supply and demand and may lead to myocardial ischemia. Increases HR and may induce/exacerbate tachyarrhythmias. Extravasation causes tissue necrosis and sloughing at site of infusion. Ephedrine (PACU only) - CORRECT ANSWER: 1. Main Actions: A sympathomimetic agent that causes vasoconstriction 2. Standing Order: Hypotension in the post -
anesthetic patient (PACU only) 3. Considerations: Can cause cardiovascular changes (excitation, tachycardia) and urinary retention. Epinephrine - CORRECT ANSWER: 1. Main Actions: An alpha -adrenergic drug producing potent vasoconstriction. It can increase coronary and cerebral perfusion pressure during CPR, but can also increase myocardial work and reduce subendocardial perfusion. 2. Standing Order: Asystole Unstabl e Bradycardia PEA V Fib/Pulseless V Tach Severe Anaphylaxis 3. Considerations: May induce or exacerbate ventricular ectopy especially when patient has electrolyte imbalance. Coronary ischemia may occur and is not related to dose, ischemic renal failure can occur with high doses. The drug of choice for severe anaphylaxis reactions because it blocks inflammatory mediator release from sensitized cells.
