ACLS Drugs dosages & uses Study Guide 2024.For poor perfusion with Bradycardia Treat with which first line treatment? - AnswerAtropine 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? - AnswerTranscutaneous pacing Dopamine 5-20mcg/kg/minute infusion OR Epinephrine 2-10mcg/min infusion What is the first line drug for acute stable bradycardia and how do you administer it? - AnswerAtropine given as 1mg IV q 3-5minutes (up to 3mg IV) Hoe does Atropine work? - AnswerReverses the cholinergic-mediated decreases in the heart rate and AV node conduction Which two AV block types will not respond to Atropine? - AnswerMobitz 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? - AnswerTCP 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? - AnswerIt can further lower the HR What can be used if bradycardia is unresponsive to Atropine? - AnswerB-adrenergic infusions (dopamine or epinephrine) What must you consider before giving B-adrenergic infusions in bradycardia? - AnswerThe pt's BP/intravascular volume status for hypovolemia What can be given for bradycardia when vasoconstriction is not desired? - AnswerDobutamine (b-adrenergic agonist) Epinephrine should be given at what dose/rate for Bradycardia? - Answer2-10mcg/min Dopamine should be given at what dose/rate for Bradycardia? - Answer5-20mcg/kg/min 1 / 2
How does Transcutaneous Pacing (TCP) work and when should it be used? - AnswerIt delivers pacing impulses to the heart through skin via cutaneous electrodes.for unstable bradycardia (hypotension, AMS, shock, ischemic chest pain) For light sedation within the RN scope of practice give which 3 things should be given before TCP if the pt's condition allows for it? - Answer-Parenteral narcotic -Parenteral benzodiazepine -Chronotropic infusion How much of a safety margin (energy above the dose at which consistent capture is observed) should you allow when using the transcutaneous pacemaker? - Answer2 mA The HR that takes on clinical significance and is more likely to contribute to arrhythmia in tachycardia is what rate? - Answer150/min or greater What are the 7 rhythms associated with unstable tachycardia? - Answer1. Sinus Tachycardia
- Atrial fibrillation
- Atrial Flutter
- Superventricular Tachycardia (SVT)
- Monomorphic Ventricular Tachycardia (giant shark teeth-looking)
- Polymorphic Ventricular Tachycardia (Mutiple random shark teeth-looking)
- Wide-complex tachycardia of uncertain type
- AnswerAdenosine 6mg IV
- / 2
What is the first line treatment for unstable tachycardia? - AnswerImmediate Synchronized Cardioversion if the QRS complex is ----seconds or greater, consider expert consultation. - Answer0.12 seconds If the width of the ORs complex is 0.12 or less treat with what two things? - AnswerVagal maneuvers and Adenosine What is the therapy for a narrow QRS with regular rhythm (4)? - Answer-Vagal maneuver -give Adenosine -give a B-blocker/calcium channel blocker -consider expert consultation If SVT does not respond to Vagal maneuvers give _____ in a large vein over 1 second.
what do you do with the pt immediately after giving Adenosine 6mg IV? - Answerelevate the arm immediately
