ALS/ACLS - Red Cross Final Exam
Questions with Correct Answers for
Specific Exam Mail
The resuscitation team suspects that hyperkalemia is the
cause of cardiac arrest in a patient brought to the
emergency department. Which finding on a 12-lead ECG
would confirm this suspicion?
Ans: Wide-complex ventricular rhythm or tall, pointed T
waves
A patient with dyspnea and a change in mental status
arrives at the emergency department. The healthcare
team completes the necessary assessments and begins to
care for the patient, including initiating cardiac
monitoring, pulse oximetry, supplemental oxygen and
vascular access. The team reviews the patient's ECG
rhythm strip, as shown in the following figure. Which agent
would the team most likely administer?
Ans: Atropine 0.5 mg every 4 to 5 minutes
Pretest - Stuvia US
,2
A patient experiencing an unstable bradyarrhythmia
does not respond to atropine or transcutaneous pacing.
Which intervention would the healthcare provider use
next?
Ans: Administration of an epinephrine infusion
A patient's ECG reveals a tachyarrhythmia. The patient is
hemodynamically stable and has a heart rate ranging
from 120 to 135 beats per minute. Based on the findings of
the secondary assessment, which statement(s) by the
patient would the team interpret as a possible
contributing cause?
Ans: 1. "I've had a terrible cold with a horrible cough and
fever the past week."
2. "I've been so anxious lately because I just lost my job."
3. "I've been vomiting for the past 2 days from a
gastrointestinal bug."
A patient's ECG reveals a narrow QRS complex with a
regular rhythm, indicating a narrow-complex
supraventricular tachyarrhythmia. The patient is
Pretest - Stuvia US
, 3
hemodynamically stable. Which intervention would be
initiated first?
Ans: Vagal maneuvers
A patient in the telemetry unit is stable. Cardiac
monitoring indicates the patient has ventricular
tachycardia with a pulse. Further assessment reveals that
the corrected QT interval is greater than 0.46 seconds.
Which treatment would be appropriate at this time?
Ans: Synchronized cardioversion
An ECG strip of a patient in the emergency department
reveals the following rhythm. Which feature would the
healthcare provider interpret as indicating atrial
fibrillation?
Ans: Absence of discrete P waves and presence of
irregularly irregular QRS complexes
A patient is brought into the emergency department. The
patient does not have a pulse. The cardiac monitor shows
Pretest - Stuvia US
