A symptomatic bradycardia exists when what 3 criteria are present?
Question 1/10
1. The heart rate is slow. 2. The patient has symptoms. 3. The symptoms are due to the slow heart rate.
1. The heart rate is fast. 2. The patient has symptoms. 3. The symptoms are due to the fast heart rate.
1. The heart rate is slow. 2. The patient has no symptoms. 3. The lack of symptoms are due to the slow heart rate.
None of the above
The primary decision point in the ACLS Bradycardia Algorithm is:
Question 2/10
The patient's heart rate
The patient's blood pressure
The determination of adequate perfusion
The presence of chest pain
Identify the correct dosing regimen of atropine to treat symptomatic bradycardia:
Question 3/10
Atropine 0.5 mg IV every 2 minutes to a maximum of 2 mg
Atropine 1 mg IV every 3-5 minutes to a maximum of 3 mg
Atropine 1 mg every 5 minutes to a maximum of 3 mg
Atropine 0.5 mg IV every 3-5 minutes to a maximum of 3 mg
What is not a precaution for TCP?
Question 4/10
TCP is contraindicated in severe hypothermia and is not recommended for asystole
Conscious patients require analgesia for discomfort unless delay for sedation will cause/contribute to deterioration
Avoid AV nodal blocking agents
Do not assess the carotid pulse to confirm mechanical capture; electrical stimulation causes muscular jerking that may mimic the carotid pulse
Identify the correct sequence of steps to performs TCP (transcutaneous pacing):
Question 5/10
1. Turn the pacer on. 2. Place pacing electrodes on the chest. 3. Set the demand rate to 50 beats/min. 4. Set the current milliamperes output 2 mA above the dose at which consistent capture is observed.
1. Place pacing electrodes on the chest. 2. Turn the pacer on. 3. Set the current milliamperes output 2 mA above the dose at which consistent capture is observed. 4. Set the demand rate to 50 beats/min.
1. Turn the pacer on. 2. Place pacing electrodes on the chest. 3. Set the demand rate to 60 beats/min. 4. Set the current milliamperes output 5 mA above the dose at which consistent capture is observed.
1. Turn the pacer on. 2. Place pacing electrodes on the chest. 3. Set the demand rate to 60 beats/min. This rate can be adjusted up or down once pacing is established. 4. Set the current milliamperes output 2 mA above the dose at which consistent capture is observed.
What drugs are appropriate forms of treatment according to the Adult Bradycardia with a Pulse Algorithm?
Question 6/10
Atropine
Dopamine
Epinephrine
All of the above
The initial treatment for bradycardia is:
Question 7/10
Dopamine
Atropine
TCP
Epinephrine
A patient has a third degree heart block. He is complaining of chest pain and he is hypotensive and diaphoretic. He also has pulmonary congestion. He has a large-bore intravenous in his left antecubital fossa. He has been given atropine 0.5 mg intravenously x3 with only a transient increase in heart rate and no improvement of symptoms. The next intervention should be:
Question 8/10
Start a dopamine infusion at 2-10 mcg/kg/minute
Start an epinephrine infusion at 2-10 mcg/minute
Attempt TCP (transcutaneous pacing)
Any of these are acceptable interventions when atropine is ineffective
Signs and symptoms of bradycardia may include:
Question 9/10
Syncope or near syncope
Decreased level of consciousness
Hypotension
All of these
The type of AV block most likely to cause cardiovascular collapse is:
Question 10/10
Sinus bradycardia
First-degree AV block
Second-degree AV block
Third-degree AV block
