With what diseases does dopamine increase?

Correct Answer: A

Rationale: The correct answer is A: Schizophrenia. Dopamine increase is associated with positive symptoms of schizophrenia such as hallucinations and delusions. In Parkinson's disease, there is a decrease in dopamine. Depression is linked to low levels of serotonin and norepinephrine, not dopamine. Anxiety is more related to imbalances in serotonin and GABA, not dopamine.

Correct Answer: A

Rationale: The correct answer is A because GABA is a neurotransmitter that functions as an inhibitory neurotransmitter in the central nervous system, reducing anxiety and excitation by inhibiting neuronal activity. GABA does not directly regulate mood (choice B), cognition and motivation (choice C), or learning and memory (choice D). GABA's primary role is in modulating neuronal activity to maintain balance and prevent overexcitation.

Correct Answer: A

Rationale: Primary prevention involves preventing disease or injury before it occurs by targeting risk factors and promoting health. This is the most effective and cost-efficient approach to improving public health. Other choices, B, C, and D, focus on interventions after the onset of disease or injury, which fall under secondary and tertiary prevention strategies. These options aim to reduce the impact of an existing condition rather than preventing it from happening in the first place. Thus, the correct choice is A as it aligns with the definition and goal of primary prevention.

Correct Answer: B

Rationale: The correct answer is B, regular exams and screening, because secondary prevention aims to detect and treat diseases in their early stages to prevent further progression. Regular exams and screening help identify potential health issues early on, allowing for prompt intervention. A, legislation to ban hazardous products, relates to primary prevention by preventing exposure to risk factors. C, cardiac rehab programs, and D, support groups, are examples of tertiary prevention aimed at managing and reducing the impact of existing health conditions.

Correct Answer: A

Rationale: The correct answer is A because alprazolam is a benzodiazepine that commonly causes drowsiness as a side effect due to its sedative properties. Respiratory depression is also a known side effect of benzodiazepines, especially when taken in high doses or with other depressants. Choice B is incorrect because benzodiazepines like alprazolam typically have a sedating effect rather than increasing energy and alertness. Choice C is incorrect as weight gain and increased appetite are not commonly associated with alprazolam use. Choice D is also incorrect because alprazolam does have side effects, such as drowsiness and respiratory depression.
