A 56-year-old man presents with an acute onset chest pressure, shortness of breath,
and diaphoresis. He has a history of hypertension and type 2 diabetes. His airway is
patent and his breathing is adequate. Your FIRST treatment should be: - CORRECT
ANSWER✔✔administer supplemental oxygen
A 39-year-old man is asystole has been unresponsive to high-quality CPR and two
doses of epinephrine. The patient is intubated and an IO catheter is in place. You
should focus on: - CORRECT ANSWER✔✔searching for reversible causes.
A 48-year-old man with a history of hypertension presents with a severe headache,
tinnitus and blurred vision. He is conscious and alert and denies any other symptoms.
His BP is 204/120 mm Hg, his pulse rate is 100 beats/min, and his oxygen saturation is
96%. The closest appropriate facility is 20 minutes away. You should: - CORRECT
ANSWER✔✔monitor his cardiac rhythm and transport
A 50-year-old man is experiencing an acute myocardial infarction. He has no prior
history of cardiac problems, takes no medications, and has no drug allergies. His
oxygen saturation is 96%. He should FIRST receive: - CORRECT ANSWER✔✔aspirin
A 59-year-old female presents with severe substernal chest pain. She is anxious and
diaphoretic. What should you do? - CORRECT ANSWER✔✔Administer aspirin
A 60-year-old man with crush chest pain has 3 mm of ST elevation in leads V1 through
V4. What should you suspect? - CORRECT ANSWER✔✔Left anterior descending
artery occlusion
A 67-year-old woman presents with severe dyspnea, coarse crackles to all lung fields,
and anxiety. She has a history of several myocardial infarctions and hypertension.
Which of the following interventions will have the MOST immediate and positive effect?
- CORRECT ANSWER✔✔Positive end-expiratory pressure ventilation
, A 70-year-old male presents with pain in his legs while walking. Within a few minutes of
sitting down, however, his symptoms resolve. What should you suspect? - CORRECT
ANSWER✔✔Peripheral arterial disease
A 70-year-old woman remains in asystole following 10 minutes of well coordinated CPR,
successful intubation, IV therapy, and three doses of epinephrine. There are no obvious
underlying causes that would explain her cardiac arrest. At this point, it would be
appropriate to: - CORRECT ANSWER✔✔seriously consider ceasing resuscitative
efforts

ANSWER✔✔are uprights in leads V1 through V6
A delta wave is identified on a cardiac rhythm strip as a(n): - CORRECT
ANSWER✔✔slurring of the upstroke of the first part of the QRS complex
A middle-aged man in a ventricular fibrillation has been refractory to several biphasic
defibrillations, well-coordinated CPR, adequately performed ventilations, and two doses
of epinephrine. What should you do next? - CORRECT ANSWER✔✔Administer 300 mg
of amiodarone via rapid IV push
A patient's 12-lead ECG shows qR complexes in leads I and aVL and rS complexes in
leads II, III, and aVF. This indicates: - CORRECT ANSWER✔✔Left anterior fascicular
block
A positive QRS deflection in lead I means the vector is heading toward the: - CORRECT
ANSWER✔✔left arm
A right-sided ECG is indicated for patients who present with: - CORRECT
ANSWER✔✔ECG evidence of an inferior infarction
After delivering a shock to a patient in pulseless ventricular tachycardia, you should: -
CORRECT ANSWER✔✔resume CPR
Cardiac arrhythmias following an acute myocardial infarction: - CORRECT
ANSWER✔✔Tend to originate from ischemic areas around the infarction
On the 12-lead ECG, extreme right axis deviation is characterized by: - CORRECT
ANSWER✔✔a negative QRS in lead I and negative QRS in lead aVF
A circumflex branch of the left coronary artery supplies the ________ wall of the left
ventricle - CORRECT ANSWER✔✔lateral
