Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?

This ACLS Quiz focuses on the bradycardia algorithm of the ACLS Protocol. Answer all 30 questions and then your practice test will be graded.

 
1.

What is generally considered the most important and clinically significant degree of block?

type I (Mobitz I)
type II (Mobitz II)
third-degree AV block
first-degree AV block
2.

Which drugs are involved in the Bradycardia Algorithm?

atropine, epinephrine, dopamine
atropine, norepinephrine, dopamine
atropine, lidocaine, adenosine
atropine, epinephrine, lidocaine
3.

Bradyarrhythmia is defined as:

any rhythm disorder with a heart rate less than 40 beats per minute
any rhythm disorder with a heart rate less than 60 beats per minute
any symptomatic rhythm disorder with a heart rate less than 50 beats per minute
any rhythm disorder with a heart rate less than 50 beats per minute
4.

Symptomatic bradycardia exists when_________.

the heart rate is slow
the patient has symptoms
the symptoms are due to a slow heart rate
all of the above are needed for symptomatic bradycardia to exist.
5.

Symptoms of bradycardia include acutely altered mental status, signs of shock, and ischemic chest discomfort.

True
False
6.

Signs of symptomatic bradycardia include hypotension and acute heart failure

True
False
7.

The primary decision point in the bradycardia algorithm is the determination of:

heart rate
adequate perfusion
blood pressure
rhythm
8.

After it is determined that the patient does not have adequate perfusion your first step is to:

prepare for transcutaneous pacing
observe and monitor the patient
give atropine while awaiting transcutaneous pacer
use defibrillator set at 200 J
9.

What is the first-line agent for the treatment of symptomatic bradycardia?

atropine
lidocaine
epinephrine
vasopressin
10.

Which rhythm is most likely to be associated with symptomatic bradycardia?

PEA
sinus rhythm
ventricular fibrillation
Mobitz II
11.

The correct dose of dopamine given in the bradycardia algorithm is:

 
5-20 mcg/kg/min infusion
2-8 mcg/kg/min infusion
5-10 mcg/kg/min infusion
1-5 mcg/kg/min infusion
12.

The key clinical question when determining steps to take for the patient with symptomatic bradycardia is:

Is the bradycardia reversible?
Does the patient respond to medications?
Are the symptoms caused by bradycardia or some other illness?
Is the patient a DNR?
13.

The treatment sequence for bradycardia with poor perfusion is:

start IV drip of dopamine or epinephrine, if ineffective begin transcutaneous pacing, and if this is not effective, give atropine
begin cpr, give epinephrine, give atropine, defibrillate, repeat epinephrine if needed.
give epinephrine, if ineffective give atropine, if atropine is ineffective start transcutaneous pacing
prepare for transcutaneous pacing, give atropine while preparing TCP, use epinephrine or dopamine while awaiting pacemaker or if pacing is ineffective.
14.

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
all of the above
15.

If transcutaneous pacing is ineffective for symptomatic bradycardia, the next step would be to prepare for:

 
 

 

 
 
begin CPR
prepare for transvenous pacing & begin an infusion of dopamine or epinephrine
prepare for pacemaker placement
give repeat doses of atropine
16.

Atropine doses of less than 0.5 mg may paradoxically result in further slowing of the heart rate.

True
False
17.

For bradycardia unresponsive to atropine, what other drug should be considered?

vasopressin
epinephrine
magnesium sulfate
all of the above
18.

If atropine fails, the treatment of choice for symptomatic bradycardia with signs of poor perfusion is ____________.

 
 
pacemaker placement
transcutaneous pacing
CPR
none of the above
19.

The correct dose of epinephrine given in the bradycardia algorithm is:

1-5 mcg/min infusion
2-8 mcg/min infusion
2-10 mcg/min infusion
5-10 mcg/min infusion
20.

The correct dose of atropine given in the bradycardia algorithm is:

1 mg atropine, may repeat up to a total dose of 3 mg
0.5 mg atropine, may repeat up to a total dose of 2 mg
0.5 mg atropine, may repeat up to a total dose of 3 mg
1 mg atropine, may repeat up to a total dose of 4 mg
21.

For transcutaneous pacing, the current milliamperes (mA) output should be:

 
set at 30 mA
set 2 mA above capture dose
set 4 mA above capture dose
set no higher than capture dose
22.

For transcutaneous pacing, the demand rate should be set at:

no higher than 60/min
started at 60-80/min with adjustment based on clinical response
started at 80/min with adjustment based on clinical response
started at 100/min and reduced to minimum for clinical response
23.

After initiating external pacing, you should assess the carotid pulse to confirm mechanical capture.

True
False
24.

Preparation for transcutaneous pacing (standby pacing) should be made for which of the following?

unstable sinus bradycardia
third degree AV block
Mobitz type II second-degree AV block
all of the above
25.

If transcutaneous pacing and drugs fail, what would be your next intervention?

defibrillation
synchronized cardioversion
transvenous pacing
CPR
26.

The following rhythm is a complete block. Which definition of complete block is correct.

One or more (but not all) of the atrial impulses fail to conduct to the ventricles due to impaired conduction.
The impulse conducting from atria to ventricles through the AV node is delayed and travels slower than normal PR interval is lengthened beyond 0.20 seconds
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.
There is no impulse generated from the SA node in the atrium but the ventricles contract from random locations below the AV Node.
27.

Identify the following rhythm.

second degree block
sinus bradycardia
complete block
sinus rhythm
28.

Transcutaneous pacing is contraindicated in the patient with ________________.

severe hypothermia
hypokalemia
chest pain
all of the above
29.

Identify the following rhythm.

second degree av block type 1
second degree av block type 2
first degree av block
30.

Identify the following rhythm.

second degree av block type 1
second degree av block type 2
first degree av block
