contract from random locations below the AV Node

16. You arrive on the scene with the code team. High-quality CPR is in progress. An
AED has previously advised “no shock indicated.” A rhythm check now finds
asystole. After resuming high-quality compressions, your next action is to: ?

Call for a pulse check.
All of the above

symptomatic bradycardia is: ?
Is the bradycardia reversible?
Does the patient respond to medications?
Are the symptoms caused by bradycardia or some other illness?
Is the patient a DNR?
the age of the patient
18. While treating a patient in VF arrest after 2 minutes (5 cycles) of CPR and 1
shock, you consider using vasopressin. Which of the following guidelines for use of
vasopressin is true? ?
give vasopressin 40 U every 3 to 5 minutes
give vasopressin for better vasoconstriction and -adrenergic stimulation
than provided by epinephrine
give vasopressin as an alternative to epinephrine in shock-refractory
VF
give vasopressin as the first-line pressor agent for clinical shock caused by
hypovolemia
give vasopressin 40 ml once
19. You prepare to cardiovert an unstable 48-year-old tachycardia woman with
the monitor/defibrillator in "synchronization" mode. She suddenly becomes
unresponsive and pulseless right when the rhythm changes to an irregular,
chaotic, VF-like pattern. You charge to 200 J and press SHOCK button, but the
defibrillator fails to deliver the shock. Why? ?
the defibrillator/monitor battery failed
sthe "sync" switch failed
you cannot shock VF in "sync" mode
a monitor lead has lost contact, producing the "pseudo-VF" rhythm
20. A 35-year-old woman has palpitations, light-headedness, and a stable
tachycardia. The monitor shows a regular narrow-complex QRS at a rate of
180/min. Vagal maneuvers have not been effective in terminating the rhythm.

The electrical shock is delivered as soon as the
operator pushes the SHOCK button to discharge the

the cardiac cycle.
The electrical shock is delivered with a peak of the R
