Which of the following answer choices is most correct regarding the underlying rhythm and coinciding appropriate treatment for this patient?

A. Pulseless electrical activity (PEA), synchronized cardioversion with biphasic 120 J
B. Pulseless ventricular tachycardia, synchronized cardioversion with monophasic 360 J
C. Ventricular fibrillation, unsynchronized cardioversion with biphasic 120 J
D. PEA, unsynchronized cardioversion with biphasic 200 J
E. Pulseless ventricular tachycardia, unsynchronized cardioversion with biphasic 120 J


Question 2#Print Question

A 70-year-old man with history of coronary artery disease has a witnessed cardiac arrest. He undergoes 10 minutes of resuscitation with return of spontaneous circulation (ROSC) but remains comatose.

Which of the following treatments for postresuscitation care is most likely to improve outcome for this patient?

A. 100% FiO2 for at least 24 hours
B. Permissive hypotension to avoid using vasopressors
C. Hypothermia between 32°C and 36°C for 24 hours
D. Glycemic control with goal range 120 to 180 mg/dL
E. Normocarbia with a PaCO2 between 35 and 45 mm Hg


Question 3#Print Question

A 23-year-old man presents to the ED after being a passenger in a high-speed motor vehicle accident. He was restrained and there was airbag deployment. Upon initial presentation to the ED, he was conversant, oriented, and following commands.

B. 15, 4
C. 13, 8
D. 10, 4


Question 4#Print Question

A 33-year-old morbidly obese man presents to the ED after being an unrestrained passenger in a high-speed motor vehicle accident. On evaluation, it is noted that he has distended neck veins, difficulty breathing, and hyperresonance to percussion on the right. Breath sounds are difficult to auscultate.

What is the MOST likely diagnosis and appropriate treatment for this patient?

A. Cardiac tamponade, pericardiocentesis
B. Cardiac tamponade, resuscitative thoracotomy
C. Tension pneumothorax (TPX), tube thoracostomy
D. TPX, needle decompression with 14G angiocath


Question 5#Print Question

A 4-year-old girl presents to the ED after being struck by a vehicle while riding her bike. She was awake and complaining of neck pain immediately after the accident but is somnolent with sonorous respirations on your examination in the ED. Her oxygen saturation is 89% and her heart rate (HR) is 50 beats/min. According to the Pediatric Acute Life Support guidelines,

what are the MOST appropriate initial steps in assessment and management for this patient?

A. First impression; cardiopulmonary resuscitation (CPR)
B. First impression; focused assessment with sonography for trauma (FAST) examination to evaluate for pericardial fluid
C. Evaluate-identify-intervene; STAT head CT
D. Evaluate-identify-intervene; intubation
