Which statement by a patient with generalized anxiety disorder for whom lorazepam (Ativan) is prescribed as needed (prn) suggests the patient understands the purpose of the medication?

Correct Answer: A

Rationale: The correct answer is A because it demonstrates the patient's understanding that lorazepam is meant to help alleviate anxiety symptoms, making it easier to communicate with their therapist. This shows insight into the medication's purpose. Choice B indicates uncertainty about the duration of treatment, not the medication's purpose. Choice C reflects stigma and concerns about others knowing, not understanding the medication's purpose. Choice D focuses on using the medication to aid sleep, not addressing anxiety symptoms directly.

Correct Answer: C

Rationale: The 'gateway hypothesis' posits that use of certain substances, like cannabis, can lead to the use of more harmful substances, such as heroin. This progression is based on the idea that trying one drug can increase the likelihood of trying others. Choice C is correct because it directly aligns with this hypothesis by stating that individuals who are addicted to heroin often have a history of prior cannabis use. This supports the notion of cannabis serving as a gateway to heroin use. Choices A, B, and D are incorrect: A: This choice discusses the addictive nature of drugs, which is not directly related to the gateway hypothesis. B: This choice mentions a correlation between cannabis use and genetic predisposition to schizophrenia, which is not directly connected to the gateway hypothesis. D: This choice is unrelated to the concept of the gateway hypothesis and discusses a different scenario altogether.

Correct Answer: B

Rationale: The correct answer is B because the statement indicates a potential issue with medication adherence. The patient's lifestyle of constantly moving between Florida and New England may disrupt the medication regimen, leading to missed doses or inconsistent treatment. This lack of adherence can impact the effectiveness of the antipsychotic medication. Choice A is not correct as it indicates a concern about weight loss, which can be a common side effect of antipsychotic medications but does not necessarily indicate a need for further education. Choice C suggests a desire to start a family, which may require additional discussions but is not directly related to medication education. Choice D involves a promise of a reward for stopping the medication, which may indicate a misunderstanding but not necessarily a need for further education.

Correct Answer: D

Rationale: The correct answer is D: Acetylcholine deficiency. Alzheimer's disease is characterized by a progressive loss of acetylcholine-producing neurons. Acetylcholine is crucial for memory, learning, and cognitive functions. A) GABA and B) Dopamine excess are not associated with Alzheimer's. C) Serotonin deficiency is not a primary factor in Alzheimer's pathology. Acetylcholine deficiency best explains the cognitive decline in Alzheimer's patients.

Correct Answer: A

Rationale: Rationale: Choice A is incorrect because triptan injections are not meant for regular preventive use, but for acute treatment of migraine headaches when they occur. Taking the medication regularly for prevention goes against its intended use and can lead to overuse and potential side effects. Choices B, C, and D are correct as they align with the appropriate use of triptan injections for acute migraine treatment, accurate information about its effects, and monitoring the effectiveness of the treatment, respectively.
