BRADYCARDIA PRACTICE TEST (ACLS)A symptomatic bradycardia exists when what 3 criteria are present?
A. 1. The heart rate is slow. 2. The patient has symptoms. 3. The symptoms are due to
the slow heart rate.
B. 1. The heart rate is fast. 2. The patient has symptoms. 3. The symptoms are due to
the fast heart rate.
C. 1. The heart rate is slow. 2. The patient has no symptoms. 3. The lack of symptoms
are due to the slow heart rate.
D. None of the above - ANSWERS-A. 1. The heart rate is slow. 2. The patient has
symptoms. 3. The symptoms are due to the slow heart rate.
The primary decision point in the ACLS Bradycardia Algorithm is:
A. The patient's heart rate
B. The patient's blood pressure
C. The determination of adequate perfusion
D. The presence of chest pain - ANSWERS-C. The determination of adequate perfusion
The decision point is deciding if the patient has adequate or poor perfusion.
If the patient has adequate perfusion, observe and monitor.
If the patient has poor perfusion, proceed to treatment.
Identify the correct dosing regimen of atropine to treat symptomatic bradycardia:
A. Atropine 0.5 mg IV every 2 minutes to a maximum of 2 mg
B. Atropine 1 mg IV every 3-5 minutes to a maximum of 3 mg
C. Atropine 1 mg every 5 minutes to a maximum of 3 mg
D. Atropine 0.5 mg IV every 3-5 minutes to a maximum of 3 mg - ANSWERS-D.
Atropine 0.5 mg IV every 3-5 minutes to a maximum of 3 mg
The correct dose of atropine in bradycardia is 0.5 mg given every 3 to 5 minutes to a
maximum dose of 3 mg. Atropine should be used cautiously in the presence of cardiac
ischemia or MI as it may worsen ischemia and increase infarct size. Doses lower than
0.5 mg may result in a paradoxical slowing of the heart.
The initial treatment for bradycardia is:
A. Dopamine
B. Atropine
C. TCP
D. Epinephrine - ANSWERS-B. Atropine
If the patient has poor perfusion, you administer atropine. If atropine is ineffective,
prepare for TCP or consider dopamine or epinephrine infusion.
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:
