With what diseases does serotonin decrease?

Correct Answer: B

Rationale: The correct answer is B: Depression. Serotonin is a neurotransmitter that plays a crucial role in regulating mood. Decreased serotonin levels are commonly associated with depression. Anxiety (A) is more linked to imbalances in other neurotransmitters like norepinephrine and GABA. Schizophrenia (C) is thought to be related to dopamine dysregulation rather than serotonin. Parkinson's disease (D) is primarily associated with a decrease in dopamine levels in the brain.

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.

Correct Answer: A

Rationale: The correct answer is A: Clonazepam, diazepam, and alprazolam. These are common benzodiazepines used to treat anxiety disorders and other conditions. Clonazepam, diazepam, and alprazolam are all examples of benzodiazepines with known anxiolytic properties. Choice B, Fluoxetine, sertraline, and paroxetine, are selective serotonin reuptake inhibitors (SSRIs) used for treating depression and other mood disorders, not benzodiazepines. Choice C, Lithium, valproate, and carbamazepine, are mood stabilizers commonly used to treat bipolar disorder and epilepsy, not benzodiazepines. Choice D is incorrect because there are indeed common benzodiazepines available for clinical use.
