Exam 37: Emergency Cardiovascular Life Support

A patient with supraventricular tachycardia (SVT) at a rate of 195/min is developing symptoms of shock and unconsciousness. At this time, what would you recommend?

After confirming respiratory arrest and securing the airway in a 1-year-old infant, at which of the following rates would you provide rescue breathing?

A patient with suspected spinal trauma is admitted to the emergency department and subsequently goes into respiratory arrest. Which of the following would be the appropriate action to initially secure an open airway in this patient?

During ACLS for a 4-year-old child in ventricular fibrillation, a shockable rhythm persists after five cycles of CPR. At this time, what would you recommend?

Most sudden deaths of cardiac origin are due to which of the following?

What is the best way to increase CPR survival rates in the field?

The automatic external defibrillator will indicate that a shock is needed if it detects which of the following rhythms? 1) Bradycardia 2) Atrial fibrillation 3) Ventricular fibrillation 4) Ventricular tachycardia

What is the proper rate of external chest compressions for infants?

What is the preferred method of securing a patent airway during CPR?

On inspection of an electrocardiographic rhythm strip, you note the following occurring in sustained "bursts" over 2 to 3 min: a rate of 195; regular rhythm; P waves and PR intervals not easily discernible; normal QRS complexes (a few are widened). What is most likely the problem?

What is the major complication associated with manual removal of foreign material from the airway?

What is the ideal route for the administration of most drugs used in emergency life-support situations?

A patient in the emergency department exhibits signs of acute upper airway obstruction and is concurrently having severe seizures that make it impossible to open the mouth. In this case, what would be the adjunct airway of choice?

What is the maximum energy level for defibrillation of children and infants?

For chest compressions to be effective, in what position must the patient be placed?

During CPR, a properly positioned endotracheal tube can do which of the following? 1) Isolate and protect the lower airway from aspiration. 2) Permit suctioning of the trachea and main stem bronchi. 3) Facilitate positive-pressure ventilation and oxygenation. 4) Provide a route for administration of selected drug agents.

During single-rescuer adult CPR, what is the proper ratio of compressions to ventilation?

Which of the following reasons explains why abdominal thrusts are not recommended for infants younger than 1 year?

After successive abdominal thrusts, the patient becomes unconscious and the airway still appears obstructed. What is the next appropriate action?

During properly performed external chest compression on an adult, how should the heel of the hand be positioned?
