Defibrillation uses brief discharges of electricity to stop dysrhythmias.

• A. Gastritis
• B. Enteritis
• C. Cholecystectomy
• D. Defibrillation

Answer: (D)

Defibrillation is the term for delivering brief electrical shocks to the heart to stop dangerous dysrhythmias and allow the heart’s rhythm to reset. The description in the statement matches this concept exactly. The other terms refer to parts of the digestive system or procedures unrelated to the heart’s electrical activity: gastritis is inflammation of the stomach, enteritis is inflammation of the intestines, and cholecystectomy is surgical removal of the gallbladder. So the best match for a procedure that uses brief electrical discharges to stop dysrhythmias is defibrillation.
