ACLS Drugs dosages & uses text bank with com plete questions and correct answ ers 2024/2025 What is the first line drug for acute stable bradycardia and how do you administer it? - ANSWER -Atropine given as 1mg IV q 3 -5minutes (up to 3mg IV) Hoe does Atropine work? - ANSWER -Reverses the cholinergic -mediated decreases in the heart rate and AV node cond uction How much of a safety margin (energy above the dose at which co nsistent capture is observed) should you allow when using the transcutaneous pacemaker? - ANSWER -2 mA For poor perfusion with Bradycardia Treat with which first line treatment? - ANSWER -Atropine 1mg IV (repeat to a total of 3mg IV) For poor perfusion with Bradycardia Treat, if the first line of treatment is ineffective, what should be provided and what med should be given? - ANSWER -
Transcutaneous pacing Dopamine 5 -20mcg/kg/minute infusion OR Epinephrine 2 -10mcg/min infusion The HR that takes on clinical significance and is more likely to contribute to arrhythmia in tachycardia is what rate? - ANSWER -150/min or greater What are the 7 rhythms associated with unstable tachycardia? - ANSWER -1. Sinus Tachycardia 2. Atrial fibrillation 3. Atrial Flutter 4. Superventricular Tachycardia (SVT) 5. Monomorphic Ventricular Tachycardia (giant shark teeth -looking) 6. Polymorphic Ventricu lar Tachycardia (Mutiple random shark teeth -looking) 7. Wide -complex tachycardia of uncertain type What is the first line treatment for unstable tachycardia? - ANSWER -Immediate Synchronized Cardioversion if the QRS complex is ----seconds or greater, cons ider expert consultation. - ANSWER -0.12 seconds Which two AV block types will not respond to Atropine? - ANSWER -Mobitz type II second -degree AV block and third -degree AV block What is the preferred treatment for Mobitz type II second -degree AV block and third -degree AV block? - ANSWER -TCP or B -adrenergic (dopamine, epinephrine) support until transcutaneous pacing can be achieved If only 0.5mg of IV Atropine is given what consequence could it have? - ANSWER -
It can further lower the HR What can be used if bradycardia is unresponsive to Atropine? - ANSWER -B-
adrenergic infusions (dopamine or epinephrine) What must you consider before giving B -adrenergic infusions in bradycardia? - ANSWER -The pt's BP/intravascular volume status for hypovolemia What can be given for bradycardia when vasoconstrictio n is not desired? - ANSWER -Dobutamine (b -adrenergic agonist) Epinephrine should be given at what dose/rate for Bradycardia? - ANSWER -2-
10mcg/min Dopamine should be given at what dose/rate for Bradycardia? - ANSWER -5-
20mcg/kg/min How does Transcutaneous Pacing (TCP) work and when should it be used? - ANSWER -It delivers pacing impulses to the heart through skin via cutaneous electrodes. for unstable bradycardia (hypotension, AMS, shock, ischemic chest pain)
