ACLS – Bradycardia Study Questions What is the drug of first choice for symptomatic bradycardia? - ✔✔Atropine 0.5 mg IV - may repeat every 3-5 minutes to a total dose of 3mg Which ECG rhythm ... is commonly associated with bradycardia? - ✔✔Which ECG rhythm is commonly associated with bradycardia? What is generally considered the most important and clinically significant degree of block? - ✔✔Complete block is generally the most important and clinically significant degree of block." It is also the most likely block to cause cardiovascular collapse. Which drugs are involved in the Bradycardia Algorithm? - ✔✔Epinephrine and dopamine are both used as an alternative to TCP and are infusions. Atropine is an IV push medication that is used to increase heart rate. Bradyarrhythmia is defined as: - ✔✔any rhythm disorder with a heart rate less than 60 beats per minute Symptomatic bradycardia exists when_________. - ✔✔the heart rate is slow , the patient has symptoms , the symptoms are due to a slow heart rate Symptoms of bradycardia can include chest discomfort or pain, shortness of breath, decreased level of consciousness, weakness, fatigue, lightheadedness, dizziness, and presyncope or syncope. True or False - ✔✔True Signs of symptomatic bradycardia include hypotension, orthostatic hypotension, diaphoresis, pulmonary congestion, runs of PVC's or VT. True or False - ✔✔True The primary decision point in the bradycardia algorithm is the determination of: - ✔✔adequate perfusion After it is determined that the patient does not have adequate perfusion your first step is to: - ✔✔give atropine 0.5 mg IV - may repeat every 3-5 minutes to a total dose of 3mg while awaiting transcutaneous pacer If atropine is ineffective r/t bradycardia what is the second sequence treatment - ✔✔transcutaneous pacing or dopamine 2 to 20 mcg/kg per minute/epinephrine 2 to 10 mcg/min The correct dose of atropine given in the bradycardia algorithm is: - ✔✔0.5 mg atropine, may repeat up to a total dose of 3 mg The correct dose of epinephrine given in the bradycardia algorithm is: - ✔✔2-10 mcg/min The correct dose of dopamine given in the bradycardia algorithm is: - ✔✔2-20 mcg/kg/min infusion The key clinical question when determining steps to take for the patient with symptomatic bradycardia is: - ✔✔Are the symptoms caused by bradycardia or some other illness? The treatment sequence for bradycardia with poor perfusion is: - ✔✔prepare for transcutaneous pacing, consider atropine while preparing TCP, use epinephrine or dopamine while awaiting pacemaker or if pacing is ineffective. Transcutaneous pacing should be started immediately if: - ✔✔there is no response to atropine , atropine is unlikely to be effective or if IV access cannot be quickly established , the patient is severely symptomatic If transcutaneous pacing is ineffective for symptomatic bradycardia, the next step would be to prepare for: - ✔✔prepare for transvenous pacing Atropine doses of less than 0.5mg may paradoxically result in further slowing of the heart rate. True or False - ✔✔True For bradycardia unresponsive to atropine, what other drug should be considered? - ✔✔epinephrine The treatment of choice for symptomatic bradycardia with signs of poor perfusion is ____________. - ✔✔transcutaneous pacing Which definition of complete block is correct. - ✔✔The impulse generated in the SA node in the atrium does not propagate to the ventricles and there is no apparent relationship between P waves and QRS complexes. Transcutaneous pacing is contraindicated in the patient with ________________. - ✔✔severe hypothermia For transcutaneous pacing, the current milliamperes (mA) output should be: - ✔✔set 2 mA above capture dose For transcutaneous pacing, the demand rate should be set at: - ✔✔started at 60/min with adjustment based on clinical response Transcutaneous pacing is not recommended for which of the following? - ✔✔asystole Preparation for transcutaneous pacing should be made for which of the following? - ✔✔unstable sinus bradycardia , unstable sinus bradycardia , Mobitz type II second-degree AV block Mobitz type II second-degree AV block - ✔✔2-10 micrograms/min If transcutaneous pacing and drugs fail, what would be your next intervention? - ✔✔transvenous pacing [Show More]
