A full-thickness skin graft may be taken from the inner thigh or labial fold to re-create which anatomic area?

You are responding at emergency status to a vehicle collision in your ambulance. As you approach an intersection with a red light in your direction, you approach cautiously, come to a complete stop at the intersection, ensure all other drivers can see you, and slowly ease your way through the intersection. These actions describe your abilities to:

A) predict the travel path of other drivers who have the right-of-way. B) ensure your right to proceed through a red light due to the established emergency. C) follow state laws regarding emergency vehicle operations. D) proceed with due regard for the safety of all drivers on the road.

Why is defibrillation in the first few minutes of cardiac arrest so critical?

A) If cardiac arrest is not treated within the first few minutes, ventricular fibrillation will convert to asystole, a non-shockable heart rhythm. B) Research has shown that a heart in cardiac arrest will continue to pump blood for a few minutes before cardiac output drops to zero. C) In the first few minutes of cardiac arrest, the blood pressure is still normal, but will drop quickly, making successful defibrillation less likely. D) In the first few minutes of cardiac arrest the heart is still warm, but begins to cool rapidly making it less receptive to a defibrillatory shock.
