A nurse is caring for a client with a diagnosis of depression. A decrease in which of the following neurotransmitters has been implicated in depression?
Gamma-aminobutyric acid (GABA) and acetyicholine
Glutamate and histamine
Norepinephrine and serotonin
Serotonin and acetylcholine
The Correct Answer is C
A. Gamma-aminobutyric acid (GABA) and acetylcholine: GABA is an inhibitory neurotransmitter that helps regulate neuronal excitability. It is not typically implicated in depression. Acetylcholine plays a role in cognitive functions and muscle contractions but is not primarily associated with depression.
B. Glutamate and histamine: Glutamate is the primary excitatory neurotransmitter in the central nervous system, and its imbalance has been linked to various neurological disorders, but it is not directly implicated in depression. Histamine, known for its role in allergic responses and wakefulness, is not typically associated with depression.
C. Norepinephrine and serotonin: Both norepinephrine and serotonin are monoamine neurotransmitters that play crucial roles in mood regulation. Decreased levels of these neurotransmitters have been strongly linked to depression. Norepinephrine is involved in the body's stress response and arousal, while serotonin is involved in mood, sleep, appetite, and other functions.
D. Serotonin and acetylcholine: Serotonin, as mentioned earlier, is significantly implicated in depression due to its role in regulating mood and emotional states. Acetylcholine, while important for cognitive functions and muscle control, is not primarily associated with depression.

Correct Answer is C
Explanation
A. The Parietal Lobe: The parietal lobe is primarily involved in processing sensory information, such as touch, temperature, and pain, as well as spatial awareness and perception. It is not directly responsible for controlling emotions.
B. The Endocrine System: The endocrine system consists of glands that secrete hormones into the bloodstream, regulating various bodily functions. While hormones can influence emotions, the endocrine system as a whole is not specifically responsible for controlling emotions.
C. The Limbic System: The limbic system, including structures like the amygdala, hippocampus, and hypothalamus, plays a crucial role in regulating emotions, memory, and motivation. The amygdala, in particular, is involved in processing emotions, especially fear and aggression, making the limbic system the correct answer.
D. The Occipital Lobe: The occipital lobe is primarily responsible for processing visual information, such as color, shape, and movement, and is not directly involved in controlling emotions.
Correct Answer is C
Explanation
A. Public: The public distance zone typically ranges from about 12 feet or more away from the individual. It's a distance appropriate for public speaking or formal interactions with a large group of people.
B. Personal: The personal distance zone is typically around 1.5 to 4 feet away from the individual. This distance is common in conversations with friends, family, or close acquaintances.
C. Intimate: The intimate distance zone is usually within 0 to 1.5 feet from the individual. It's reserved for very close relationships, such as intimate partners or close family members.
D. Social: The social distance zone is approximately 4 to 12 feet away from the individual. It's the distance used in most social interactions, such as conversations with colleagues or acquaintances.
