Choice C rationale: Diphenhydramine is not involved in preventing axonal conduction.

Correct Answer is B
Explanation
Choice A rationale: Physical dependence is a state where the body has adapted to the presence of the opioid, and abrupt cessation may lead to withdrawal symptoms. However, the patient's statement indicates tolerance more than physical dependence.
Choice B rationale: The patient is at risk for tolerance, which is the need for an increased dose of a substance to achieve the same effect. This is common in chronic opioid therapy.
Choice C rationale: Abstinence syndrome is another term for withdrawal syndrome, and this is more associated with sudden cessation of opioids.
