  1. Question 1

    Q1. In a scenario where a person uses a TENS (Transcutaneous Electrical Nerve Stimulation) device to alleviate pain, what is the intended outcome of the device?

    • A) The device generates an electric field that blocks pain signals to the brain.
    • B) The device generates an electric field that enhances neuronal excitability and pain perception.
    • C) The device generates an electric field that modulates the release of neurotransmitters involved in pain modulation.
    • D) The device generates an electric field that increases the strength of the pain signal.

    Answer: The device generates an electric field that blocks pain signals to the brain.

    Explanation: The device is intended to block pain signals to the brain by generating an electric field that interferes with pain transmission.
