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.

A. Substance abuse disorder is defined as physical dependence on a drug. B. Repeated use of certain drugs can cause molecular changes in the brain. C. Treatment for substance abuse disorder must be voluntary to be successful. D. Medications should not be used to treat substance abuse disorder.

Correct Answer is B

Explanation

Choice A rationale: Physical dependence is one aspect of substance use disorder, but it does not encompass the entire definition.
Choice B rationale: Repeated use of certain drugs can lead to molecular changes in the brain, contributing to addiction.
Choice C rationale: Treatment for substance abuse disorder can be effective even if not entirely voluntary, as involuntary treatment may be court-mandated or involve other external factors.
Choice D rationale: Medications, such as methadone and buprenorphine, are commonly used in the treatment of substance use disorder, challenging the idea that medications should not be used.
