(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
, ACLS Drugs dosages & uses
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)
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)

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
