QUESTION 1
A 65-year-old male presents with heart rate of 38 bpm, blood pressure 85/50 mmHg, and confusion. What is
the most appropriate initial intervention?
A. Administer dopamine 5 mcg/kg/min IV infusion
B. Administer atropine 0.5 mg IV push
C. Prepare for transcutaneous pacing
D. Administer epinephrine 1 mg IV push
Rationale: Symptomatic bradycardia with hemodynamic compromise should be treated with atropine 0.5 mg
IV push every 3-5 minutes (maximum 3 mg). Atropine blocks vagal tone and increases heart rate.
Transcutaneous pacing is used if atropine is ineffective.
QUESTION 2
A 70-year-old female presents with bradycardia at 42 bpm and is asymptomatic with a blood pressure of
130/80 mmHg. What is the most appropriate intervention?
A. Administer atropine 0.5 mg IV push
B. Monitor the patient and observe
C. Prepare for transcutaneous pacing
D. Administer dopamine 5 mcg/kg/min IV infusion
Rationale: Asymptomatic bradycardia does not require immediate treatment. The patient should be
monitored and observed. Treatment is only indicated for symptomatic bradycardia with hemodynamic
compromise.
QUESTION 3
A 55-year-old male presents with heart rate of 32 bpm, chest pain, and hypotension. He has received atropine
0.5 mg IV push without improvement. What is the next appropriate intervention?
A. Administer another dose of atropine 1 mg IV push
B. Prepare for transcutaneous pacing
,2
C. Administer dopamine 5 mcg/kg/min IV infusion
D. Administer epinephrine 2-10 mcg/min IV infusion
Rationale: When symptomatic bradycardia is unresponsive to atropine, transcutaneous pacing is the next
appropriate intervention. Transcutaneous pacing provides temporary pacing until a transvenous pacemaker
can be placed.
QUESTION 4
What is the maximum dose of atropine for symptomatic bradycardia?
A. 1 mg
B. 2 mg
C. 3 mg
D. 4 mg
Rationale: The maximum dose of atropine for symptomatic bradycardia is 3 mg (0.04 mg/kg). Atropine is
given as 0.5 mg IV push every 3-5 minutes. Higher doses are not recommended and may cause toxicity.
QUESTION 5
A 68-year-old male presents with heart rate of 150 bpm, narrow-complex tachycardia, and hypotension. What
is the most appropriate intervention?
A. Administer adenosine 6 mg IV push
B. Perform synchronized cardioversion at 120-200 J
C. Administer amiodarone 150 mg IV over 10 minutes
D. Administer diltiazem 20 mg IV push
Rationale: Unstable narrow-complex tachycardia requires immediate synchronized cardioversion. The energy
dose for biphasic cardioversion is 120-200 J. Adenosine is used for stable SVT, not unstable patients.
QUESTION 6
A 52-year-old female presents with heart rate of 160 bpm, narrow-complex tachycardia, and is stable with a
blood pressure of 110/70 mmHg. What is the most appropriate intervention?
A. Perform synchronized cardioversion at 100 J
B. Administer adenosine 6 mg IV push
C. Administer amiodarone 150 mg IV over 10 minutes
D. Administer diltiazem 20 mg IV push
, 3
Rationale: Stable narrow-complex tachycardia (SVT) is treated with adenosine 6 mg IV push. If ineffective, a
12 mg IV push can be given. Adenosine is the first-line treatment for stable SVT.
QUESTION 7
A 60-year-old male presents with heart rate of 180 bpm, wide-complex tachycardia, and hypotension. What is
the most appropriate intervention?
A. Administer amiodarone 150 mg IV over 10 minutes
B. Perform synchronized cardioversion at 100-120 J
C. Administer adenosine 6 mg IV push
D. Administer lidocaine 1-1.5 mg/kg IV push
Rationale: Unstable wide-complex tachycardia requires immediate synchronized cardioversion. The energy
dose for biphasic cardioversion is 100-120 J. If the patient becomes pulseless, proceed with defibrillation.
QUESTION 8
A 58-year-old female presents with heart rate of 170 bpm, wide-complex tachycardia, and is stable with a
blood pressure of 110/70 mmHg. What is the most appropriate intervention?
A. Perform synchronized cardioversion at 100 J
B. Administer amiodarone 150 mg IV over 10 minutes
C. Administer adenosine 6 mg IV push
D. Administer lidocaine 1-1.5 mg/kg IV push
Rationale: Stable monomorphic VT (wide-complex tachycardia) is treated with amiodarone 150 mg IV over
10 minutes. Synchronized cardioversion is reserved for unstable patients. Adenosine is not effective for wide-
complex tachycardia.
QUESTION 9
A 62-year-old male presents with heart rate of 44 bpm, dizziness, and mild hypotension. Atropine 0.5 mg IV
push is given. The heart rate increases to 55 bpm, but the patient remains dizzy. What should be done next?
A. Administer another dose of atropine 0.5 mg IV push
B. Prepare for transcutaneous pacing
C. Administer dopamine 5 mcg/kg/min IV infusion
D. Administer epinephrine 2-10 mcg/min IV infusion
Rationale: When symptomatic bradycardia persists or is unresponsive to atropine, transcutaneous pacing is
the next appropriate intervention. Atropine may have partially increased heart rate but symptoms persist.
