A patient has taken a narcotic analgesic for chronic pain for several

patient has been taking more than the prescribed dosage. The patient
has normal vital signs, is awake and alert, and reports mild pain. What
does the provider suspect is responsible for the patient's response?
A. This patient exhibits a negative placebo effect with a
reduced response to the drug.

B. This patient has developed tachyphylaxis because of
repeated exposure to the drug.

which has increased the minimal effective concentration
(MEC) needed for analgesic effect.
