At a minimum threshold, how many milliamps of current through the body produces a condition where most people would suffer ventricular fibrillation and could only be resuscitated with a ventricular defibrillator?
AI Explanation
The correct answer is D) 75 mA for 5 seconds.
This is the correct answer because the minimum threshold of current through the body that can produce ventricular fibrillation, a condition that requires a ventricular defibrillator for resuscitation, is generally considered to be around 75 mA for a duration of 5 seconds. Exposure to this level of current can disrupt the normal electrical activity of the heart, leading to the life-threatening condition of ventricular fibrillation.
The other answer choices are incorrect because they do not accurately represent the threshold for ventricular fibrillation. Option A (3 to 7 mA) is too low, while options B (10 to 16 mA) and C (30 mA) are also below the accepted threshold for this condition.
