The healthcare team completes the necessary
assessments and begins to care for the patient,
including initiating cardiac monitoring, pulse
oximetry, supplemental oxygen and vascular ac-
cess. The team reviews the patient's ECG rhythm
strip, as shown in the following figure. Which
agent would the team most likely administer?

brought to the emergency department. Which
finding on a 12-lead ECG would confirm this sus-

5. A patient's ECG reveals a narrow QRS complex Vagal maneuvers

first if it does not delay other interventions?
6. A patient in the telemetry unit is stable. Cardiac Synchronized cardioversion
monitoring indicates the patient has ventricular
tachycardia with a pulse. Further assessment re-
veals that the corrected QT interval is greater
than 0.46 seconds. Which treatment would be
appropriate at this time?

9. A patient with acute renal failure experiences Hyperkalemia
cardiac arrest. Just before the cardiac arrest, the
patient's ECG showed peaked T waves. What
might be causing the patient's cardiac arrest?
10. A member of the resuscitation team is preparing 120 to 200 joules
to defibrillate a patient in cardiac arrest using a
biphasic defibrillator. The team member would
set the energy dose according to the manufac-
turer's recommendations, which is usually:
