You are evaluating a 48-year-old man with crushing substernal chest pain. The patient is
pale, diaphoretic, cool to the touch, and slow to respond to your questions. The blood
pressure is 58/32 mm Hg, the heart rate is 190/min, the respiratory rate is 18
breaths/min, and the pulse oximeter is unable to obtain a reading because there is no radial
pulse. The lead II ECG displays a regular wide-complex tachycardia. What
intervention should you perform next?
A. Procedural sedation
B. 12-lead ECG
C. Amiodarone administration
D. Synchronized cardioversion - ANSWER-D. Synchronized cardioversion

arrest period for patients who achieve return of spontaneous circulation ROSC?

B. Responding to verbal commands
C. Patient age greater than 60 years
D. Desire to provide coronary reperfusion (eg, PCI) - ANSWER-B. Responding to verbal
commands
,What is the potential danger of using ties that pass circumferentially around the patient's
neck when securing an advanced airway?

D. Does not adequately secure the airway device - ANSWER-C. Obstruction of venous return
from the brain
