The nurses caring for a child are concerned about the child's frequent requests for pain medication. During a team conference, a new nurse suggests they consider administering a placebo instead of the usual pain medication to see how the child responds. The team educates the nurse on why this is not appropriate and bases the decision on what knowledge?
- A. This practice is unjustified and unethical.
- B. This practice is effective in determining whether a child's pain is real.
- C. The absence of a response to a placebo means the child's pain has an organic basis.
- D. A positive response to a placebo will not occur if the child's pain has an organic basis.
Correct Answer: A
Rationale: The correct answer is A. The use of placebos without the patient's consent is unethical and goes against the principles of beneficence and autonomy. Choice B is incorrect because using placebos does not provide reliable information about the presence or severity of the pain; it only indicates the response to the placebo itself. Choice C is wrong as the absence of a response to a placebo does not definitively mean that the child's pain has an organic basis; there could be various reasons for the lack of response. Choice D is also incorrect as individuals may have a positive response to a placebo even if their pain has a significant organic cause. Therefore, the most appropriate response is A, emphasizing the ethical concerns surrounding the use of placebos without informed consent.
