  1. Question 1

    Q1. A surgeon implanting a pacemaker in a patient must carefully manage the risk of electrical shock. What is a primary cause of electrical shock during pacemaker implantation?

    • A) Current leakage due to faulty insulation
    • B) Current diversion through the heart's conduction system
    • C) Voltage fluctuations during implantation
    • D) Current flow due to poor surgical technique

    Answer: Current diversion through the heart's conduction system

    Explanation: Electrical shock during pacemaker implantation can occur due to current diversion through the heart's conduction system.
