A 57-year-old woman has palpitations, chest discomfort, and tachycardia. The monitor shows a regular wide-complex QRS at a rate of 180 bpm. She becomes diaphoretic, and her bp is 80/60 mmHG. Which action next? Perform electrical cardioversion (pg.79) You arrive on scene with the code team. High quality CPR is in progress. An AED has previously advised "no shock indicated." A rhythm now finds asystole. After resuming high-quality compressions, which acton next? Establish IV or IO access (pg. 117) 00:23 01:29 A pt is in pulseless V-Tach. Two shocks and 1 dose of epi have been given. Which drug next? Amiodarone 300omg bolus Stroke pt (question 4/20) admin Aspirin A pt is in cardiac arrest. High quality compressions are given. The pt is intubated, and a IV has been started. The rhythm is asystole. What drug/dose do you give? Epinephrine 1 mg A monitored pt in the ICU developed a sudden onset of narrow-complex tachycardia at a rate of 220 bpm. The pts bp 128/58, CO2 38, O2 98%. There is vascular access in the left arm, and the pt has not been given any vasoactive drugs. A 12 lead confirms supra-ventricular tachycardia with no evidence of ischemia or infarction. The heart rate has not responded to vagal maneuvers. What next? Admin adenosine 6 mg IV push (pg. 79) pt in cardiac arrest. v fib has been refractory to second shock. Which dug administer first? Epi 1 mg A pt is in cardiac arrest. Ventricular fibrillation has been refractory to an initial shock. If no pathway for medication administration is in place, which method is preferred? (a) Central line (b) Endotracheal tube (c) External jugular vein (d) IV or IO IV or IO A patient has sinus bradycardia with a heart rate of 36 bpm. Atropine has been administered to a total of 3 mg. A pacemaker has failed to capture. The pt is confused, bp 88/56 mmHg. Which therapy next? Epi 2-10 mcg/min A pt with sinus brady and hr 42 bpm is diaphoretic and bp 80/60. What is the initial dose of atropine? 1 mg In which situation does bradycardia require tx? hypotension A pt is in refractory v-fib. CPR in progress. One dose of epi was given after 2nd shock. An anitarrhythmic drug was given after 3rd shock. Which med next? Epi 1 mg (pg. 117)
