Questions and Answers
You are on the scene w/ a 28-year-old female patient complaining of chest pain. A 12-lead
shows normal sinus rhythm with a pulse of 88 bpm. What structure of the cardiac conduction
system is responsible for this rhythm and rate? - answer✔✔SA Node
*"Primary pacemaker"- intrinsic rate of 60-100bpm.
In the human heart, the right ventricle pumps what? - answer✔✔Deoxygenated blood to
pulmonary circulation
Why must you question a patient about ED drug use prior to administration of nitroglycerin? -
answer✔✔Administration of nitroglycerin can cause dangerous hypotension if there has been

answer✔✔sodium, positive
What heart rhythm often leads to ventricular fibrillation? - answer✔✔Ventricular tachycardia
You are responding to an unresponsive child at a school playground. You arrive to find a 10-
year-old male unresponsive, pulseless, and apneic. Teachers on scene say the child was hit with a
softball in his chest and fell to the ground. What is the most likely cause for the patient's sudden
cardiac arrest? - answer✔✔Commotio Cordis
*Direct blow to the chest during the heart's repolarization period causes the patient to go into v-
fib. Early defibrillation is best treatment.
