    Homeostasis: TEAS Practice Question with Answer & Explanation

    An original TEAS 7-style science practice question, written for nursing-school applicants — with a full breakdown of every answer choice.

    Question

    Sweating in response to increased body temperature is an example of what mechanism?

    • A.Positive feedback
    • B.Negative feedback
      Correct
    • C.Genetic drift
    • D.Active immunity

    Correct answer: B. Sweating opposes the temperature increase and returns the body toward its set point, demonstrating negative feedback.

    Why B is correct

    Sweating opposes the temperature increase and returns the body toward its set point, demonstrating negative feedback.

    How to solve this TEAS question

    Identify what the question is testing, eliminate choices that conflict with the relevant rule or evidence, and then select the option that directly answers the prompt.

    Review the alternatives

    The other choices do not satisfy the scientific fact, mathematical operation, language rule, or reading evidence tested by this question. Always compare each option with the exact wording of the prompt before deciding.

    Quick study tip: Negative feedback reverses the original change.
