A client who received an IV antibiotic mistakenly believed she was receiving opioid analgesia and reported a few minutes later that the medication had relieved her pain. Which of the following is the most likely reason for the client's response?
Correct answer
C
Rationale
Believing the antibiotic was an opioid likely caused a placebo effect (C), where expectation of relief reduces perceived pain. Lying (A), antibiotic effect (B), or coincidence (D) are less likely.
