Question 1
A 62-year-old male is brought to the emergency department experiencing crushing
substernal chest pain. While connected to a 12-lead cardiac monitor, he suddenly
loses consciousness and becomes completely pulseless. The monitor reveals a
,chaotic, jagged electrical waveform with no identifiable P waves, QRS complexes,
or T waves. What is the immediate priority therapeutic intervention for this
cardiac arrest rhythm?
A. Deliver a synchronized cardioversion shock at 100 Joules.
B. Initiate a high-volume continuous intravenous infusion of Amiodarone.
C. Perform immediate endotracheal intubation and check pupillary reflexes.
D. Initiate immediate high-quality CPR and deliver an unsynchronized
defibrillation shock as soon as the equipment arrives.
CORRECT ANSWER: D
RATIONALE: The presentation of a chaotic, jagged waveform with zero
recognizable complexes in an unresponsive, pulseless patient describes
Ventricular Fibrillation (VF), a shockable cardiac arrest rhythm. According to
standard AHA ACLS guidelines, the primary, non-negotiable treatment priority is
to initiate chest compressions to maintain coronary perfusion and defibrillate
(deliver an unsynchronized shock) immediately to restore a functional
myocardial pacemaker rhythm. Synchronized cardioversion is contraindicated
because there are no R waves to synchronize the shock to.
Question 2
The emergency resuscitation team is managing an adult patient in pulseless cardiac
arrest. The cardiac monitor displays a regular, organized ventricular rhythm with a
rate of 70 beats per minute, but the team confirms the patient lacks a palpable
carotid pulse.
,Based on the clinical findings and the total mechanical breakdown illustrated
above, what is the required pharmacological intervention during the next cycle of
CPR?
A. Administer a rapid intravenous bolus of Adenosine 6 mg via a central line.
B. Deliver an unsynchronized defibrillation shock at 360 Joules.
C. Administer Epinephrine 1 mg intravenously or intraosseously every 3 to 5
minutes.
D. Initiate transcutaneous cardiac pacing at a target rate of 80 bpm.
CORRECT ANSWER: C
RATIONALE: The combination of an organized electrical rhythm on the
monitor screen paired with an absolute lack of a palpable pulse defines Pulseless
Electrical Activity (PEA). As visualized in the chart, electrical activity does not
translate into mechanical cardiac output. PEA is a non-shockable rhythm;
therefore, defibrillation is useless. The core management consists of continuous
high-quality CPR, looking for and reversing underlying causes (H's and T's), and
administering Epinephrine 1 mg IV/IO every 3 to 5 minutes to promote alpha-1
mediated vasoconstriction and maximize coronary perfusion pressure.
Question 3
A 45-year-old female presents to the emergency department complaining of an
acute onset of palpitations, shortness of breath, and a racing heart rate. The monitor
displays a regular, narrow-complex tachycardia at a rate of 185 beats per minute.
, Her blood pressure is stable at 118/74 mmHg, and she denies chest pain or altered
mental status. Which initial intervention is recommended for this stable
supraventricular tachycardia?
A. Deliver an immediate unsynchronized defibrillation shock at 200 Joules.
B. Instruct the patient to perform a vagal maneuver, such as blowing into a 10
mL syringe while semi-recumbent.
C. Administer an intravenous push dose of Atropine sulfate 1 mg rapidly.
D. Initiate an urgent synchronized cardioversion protocol.
CORRECT ANSWER: B
RATIONALE: For a regular, narrow-complex Supraventricular Tachycardia
(SVT) in a hemodynamically stable patient (normal blood pressure, clear
consciousness, no ischemic signs), the first-line intervention is to attempt vagal
maneuvers (such as the modified Valsalva maneuver). This increases
parasympathetic tone to slow AV node conduction. If vagal maneuvers fail to
convert the rhythm, the next step is the rapid administration of Adenosine (6 mg
IV push, followed by 12 mg if needed). Synchronized cardioversion is reserved for
unstable tachycardias.
Question 4
A 74-year-old female is tracking an acute inferior wall myocardial infarction.
While monitoring her vitals, her heart rate drops to 38 beats per minute, and her
blood pressure falls to 84/50 mmHg. She is dizzy, diaphoretic, and confused. The
monitor reveals a regular bradycardic rhythm with a prolonged, constant PR
interval preceding every QRS complex. Which medication is designated as the
first-line choice for symptomatic bradycardia?
A. Epinephrine 1 mg rapid IV push
B. Amiodarone 300 mg bolus
C. Atropine sulfate 1 mg intravenously, repeated every 3 to 5 minutes up to a
maximum dose of 3 mg.
D. Lidocaine 1.5 mg/kg slow loading infusion
CORRECT ANSWER: C
RATIONALE: This patient is experiencing hemodynamically symptomatic
bradycardia, as evidenced by hypotension and altered mental status. According to
the current AHA ACLS guidelines, Atropine sulfate 1 mg IV is the first-line drug
