Wide-complex ventricular rhythm or tall, pointed T waves -CORRECTANSWER 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?
Atropine 0.5 mg every 4 to 5 minutes -CORRECTANSWER 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?
Administration of an epinephrine infusion -CORRECTANSWER A patient experiencing
an unstable bradyarrhythmia does not respond to atropine or transcutaneous pacing.
Which intervention would the healthcare provider use next?
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." -
CORRECTANSWER 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?
Vagal maneuvers -CORRECTANSWER A patient's ECG reveals a narrow QRS
complex with a regular rhythm, indicating a narrow-complex supraventricular
tachyarrhythmia. The patient is hemodynamically stable. Which intervention would be
initiated first?
Synchronized cardioversion -CORRECTANSWER 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?
Absence of discrete P waves and presence of irregularly irregular QRS complexes -
CORRECTANSWER 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?
