1. Question: Increases serum levels of other drugs that are substrates of

that enzyme.

Answer: Enzyme inhibitors

Explanation: Enzyme inhibitors, particularly those affecting the

cytochrome P450 system, reduce the metabolism of su bstrates they affect, subsequently raising their serum concentrations. This can lead to potentially dangerous toxic levels, making it critical for healthcare providers to monitor drug interactions and adjust dosages accordingly in patients on polypharmacy.

2. Question: Decreases serum levels of other drugs that are substrates of

that enzyme.

Answer: Enzyme inducers

Explanation: Enzyme inducers enhance the metabolic activity of certain

enzymes, resulting in faster clearance of substrate drugs and lower serum levels. This effect can lead to subtherapeutic drug concentrations, which may necessitate dosage adjustments to maintain efficacy. Recognizing induction effects is important for clinicians managing medications in patients with complex treatment regimens.

3. Question: Part of the brain that regulates powerful emotions such as fear,

rage, and sexual desires.

Answer: Amygdala

Explanation: The amygdala is a crucial component of the limbic system

and plays a central role in processing emotions, particularly negative emotions like fear and aggression. Its functioning is essential for the 2 / 4

formation of emotional memories and the autonomic responses tied to emotional stimuli, which have significant implications for anxiety and mood disorders.

4. Question: The relay station for sensory information.

Answer: Thalamus

Explanation: The thalamus acts as a critical relay center in the brain for

sensory information, channeling input to the appropriate cortical areas for further processing. It integrates and transmits information related to touch, pain, temperature, vision, and hearing, playing an essential role in sensory perception and consciousness.

5. Question: Essential for maintaining homeostasis, controls basic needs

such as sleep-wake cycles.

Answer: Hypothalamus

Explanation: The hypothalamus is instrumental in maintaining the body’s

internal balance by regulating autonomic functions such as hunger, thirst, temperature, and sleep-wake cycles. Its interactions with the endocrine system, particularly through hormone release, underscore its influence on mood and physiological responses to stress.

6. Question: This lobe is involved in executive functioning, higher-order

planning, speech, and motivation.

Answer: Frontal Lobe/Prefrontal Cortex

Explanation: The frontal lobe, specifically the prefrontal cortex, is

essential for complex cognitive behaviors such as decision-making, social 3 / 4

interaction, and impulse control. It regulates planning and execution of tasks and is heavily involved in personality characteristics. Dysfunction in this area can contribute to a variety of psychiatric conditions, such as ADHD and schizophrenia.

7. Question: The study of the use of psychotropic medications in the

treatment of psychiatric disorders.

Answer: Psychopharmacology

Explanation: Psychopharmacology is the field that explores the effects of

medications on mood, behavior, and psychiatric symptoms. It involves examining how various classes of psychotropic drugs, such as antidepressants, antipsychotics, and anxiolytics, are utilized to manage mental health disorders. This discipline is essential for mental health professionals as it informs treatment plans and medication management strategies.

8. Question: The study of what the body does to drugs.

Answer: Pharmacokinetics

Explanation: Pharmacokinetics focuses on the processes of absorption,

distribution, metabolism, and excretion (ADME) of drugs within the body. It provides insight into how different factors—such as age, weight, and organ function—affect drug action and dosing parameters, which is crucial for ensuring effective and safe medication use in psychiatric care.

9. Question: The study of what the drug does to the body.

Answer: Pharmacodynamics
