Update; Questions & Answers
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?
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
ST
rhythm strip, as shown in the following figure. Which agent would the team most
likely administer?
Atropine 0.5 mg every 4 to 5 minutes
O
A patient experiencing an unstable bradyarrhythmia does not respond to atropine or
IC
transcutaneous pacing. Which intervention would the healthcare provider use next?
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?
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 hemodynamically
stable. Which intervention would be initiated first?
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?
Synchronized cardioversion
ST
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?
Absence of discrete P waves and presence of irregularly irregular QRS complexes
O
A patient is brought into the emergency department. The patient does not have a
pulse. The cardiac monitor shows the following rhythm. The team interprets this as
IC
which condition?
Ventricular tachycardia
A patient with acute renal failure experiences cardiac arrest. Just before the cardiac
arrest, the patient's ECG showed peaked T waves. What might be causing the
patient's cardiac arrest?
Hyperkalemia
A member of the resuscitation team is preparing to defibrillate a patient in cardiac
arrest using a biphasic defibrillator. The team member would set the energy dose
according to the manufacturer's recommendations, which is usually:
120 to 200 joules
