ACLS Drugs Dosages & Uses ( Updated 2024 ) Complete Questions & Answers (Solved) 100% Correct
- 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
- 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 conduction
- 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) sup- port 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 vasoconstriction is not desired?-
Answer: Dobutamine (b-adrenergic agonist)
- Epinephrine should be given at what dose/rate for Bradycardia?
Answer: -2-10mcg/min 1 / 2
- 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)
- 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 pace- maker?
Answer: 2 mA
- 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:
- 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
- What is the first line treatment for unstable tachycardia?
Answer: Immediate Synchronized Cardioversion
- if the QRS complex is ------------- seconds or greater, consider expert consultation.-
Answer: 0.12 seconds
- If the width of the ORs complex is 0.12 or less treat with what two things?-
Answer: Vagal maneuvers and Adenosine
