Which of the following is this fracture?

On inspection of a patient's ECG strip, you note no identifiable P waves; rapid irregular undulations of the isoelectric line; and an irregular ventricular rhythm. In addition, the precordial cardiac rate is greater than the peripheral pulse rate. The most likely problem is:

A. 2nd degree (Wenckebach) heart block B. ventricular fibrillation C. atrial fibrillation D. ventricular tachycardia

If a person survives the initial trauma from a shotgun wound at close range:

A) nervous system damage is likely due to the internal dispersal of the pellets. B) contaminants that were driven into the wound can cause a severe infection. C) he or she typically dies within 24 hours secondary to liver or renal failure. D) it is likely that only soft tissue was injured and major organs were spared
