In the human heart, the right ventricle pumps what? -
Deoxygenated blood to pulmonary circulation
Why must you question a patient about ED drug use prior to administration of

cause for the patient's sudden cardiac arrest? -
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.
When performing chest compressions, what should you allow time for between each
compression? -
Recoil
You are called to an unknown "patient down" at a private residence. As you get inside
and into the back bedroom, you can see that there is a woman face down and
