Your long-term care patient has chronic pain and at this point in time, the patient needs increasing dosages to adequately control this pain. What is this patient most likely affected by?
Correct Answer: D
Rationale: The correct answer is D: Drug tolerance. When a patient needs increasing dosages to achieve the same pain relief, it indicates the development of drug tolerance. This means the body has adapted to the drug, requiring higher doses to produce the same effect. Choice A, drug addiction, is incorrect because drug addiction involves a psychological and physical dependence on the drug, which is not described in the scenario. Choice B, drug interactions, is incorrect as it refers to the effects when multiple drugs interact with each other, not the situation described. Choice C, drug side effects, is also incorrect as it pertains to the unintended effects of a drug, not the need for higher doses to control pain.
