A nurse is explaining the role of neurotransmitters in the pathophysiology of MDD to a group of nursing students. Which neurotransmitters are mentioned in the text as being involved in regulating mood, motivation, reward, cognition, and stress response?

Acetylcholine and gamma-aminobutyric acid (GABA).

Glutamate and epinephrine.

Serotonin, dopamine, and norepinephrine.

Endorphins and oxytocin.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Acetylcholine and gamma-aminobutyric acid (GABA) are not the primary neurotransmitters involved in regulating mood, motivation, reward, cognition, and stress response. Acetylcholine plays a role in memory and muscle control, while GABA is an inhibitory neurotransmitter that helps regulate anxiety and sleep. These neurotransmitters are not as closely associated with the functions mentioned in the question.

Choice B rationale:

Glutamate is a major excitatory neurotransmitter in the central nervous system, and epinephrine (also known as adrenaline) is a hormone that prepares the body for the fight-or-flight response. While both glutamate and epinephrine play important roles in various physiological responses, they are not primarily responsible for regulating mood, motivation, reward, cognition, and stress response as mentioned in the question.

Choice C rationale:

Serotonin, dopamine, and norepinephrine are all key neurotransmitters involved in the regulation of mood, motivation, reward, cognition, and stress response. These neurotransmitters have been extensively studied in the context of mood disorders like Major Depressive Disorder (MDD). Serotonin is often associated with feelings of well-being and happiness, dopamine is linked to pleasure and reward pathways, and norepinephrine is involved in the body's stress response. Imbalances in these neurotransmitters have been implicated in the development of mood disorders.

Choice D rationale:

Endorphins and oxytocin are important neurotransmitters, but they are not as directly related to the regulation of mood, motivation, reward, cognition, and stress response as the neurotransmitters mentioned in choice C. Endorphins are known for their role in pain modulation and feelings of pleasure, while oxytocin is often referred to as the "bonding hormone" and is associated with social connections and childbirth.

Correct Answer is C

Explanation

Choice A rationale:

Increased appetite is not a commonly associated side effect of antidepressant medications. In fact, some antidepressants can lead to decreased appetite or weight loss as side effects.

Choice B rationale:

Hypertension (high blood pressure) is generally not a common side effect of most antidepressant medications. However, there are specific cases where certain antidepressants might have an impact on blood pressure, but it's not a typical side effect across the board.

Choice C rationale:

This is the correct statement. Insomnia, or difficulty sleeping, is a commonly reported side effect of many antidepressant medications. It can disrupt sleep patterns and lead to increased sleep difficulties, which might exacerbate existing sleep problems or contribute to new ones.

Choice D rationale:

Excessive energy is not a common side effect associated with antidepressant use. Antidepressants typically work to regulate mood and alleviate symptoms of depression, and excessive energy would not align with the expected effects of these medications.

A. "Chronic stress can lead to hyperactivity of the HPA axis, resulting in elevated levels of cortisol that can support neuronal growth and survival.". B. "Chronic stress can lead to hypoactivity of the HPA axis, resulting in reduced levels of cortisol that enhance neurogenesis and synaptic plasticity.". C. "Chronic stress can lead to hyperactivity of the HPA axis, resulting in elevated levels of cortisol that can impair neurogenesis and synaptic plasticity.". D. "Chronic stress can lead to hypoactivity of the HPA axis, resulting in reduced levels of cortisol that improve neurotrophic factors and cognitive function.".

Correct Answer is C

Explanation

Choice A rationale:

Chronic stress is known to activate the Hypothalamic-Pituitary-Adrenal (HPA) axis, which leads to increased cortisol production. While cortisol is important for various physiological functions, chronic elevation of cortisol due to stress can actually have detrimental effects on the brain. Elevated cortisol levels have been associated with impaired neurogenesis (the formation of new neurons) and synaptic plasticity (the ability of synapses to change and adapt), both of which play crucial roles in maintaining cognitive function and mental health.

Choice B rationale:

This statement is not accurate. Chronic stress typically leads to hyperactivity, not hypoactivity, of the HPA axis, resulting in increased levels of cortisol. The increased cortisol levels can negatively impact neurogenesis and synaptic plasticity, which are key factors in depression and cognitive function.

Choice C rationale:

This is the correct statement. Chronic stress triggers hyperactivity of the HPA axis, causing elevated levels of cortisol. While cortisol is meant to help the body cope with stress in the short term, chronic elevation can lead to adverse effects on the brain. High cortisol levels have been linked to impaired neurogenesis and synaptic plasticity, contributing to the development of depression and cognitive deficits.

Choice D rationale:

This statement is not accurate. Chronic stress tends to lead to hyperactivity of the HPA axis and elevated cortisol levels. Reduced cortisol levels, as suggested in this choice, are not commonly associated with chronic stress and its impact on depression.
