A nurse is teaching a client about the nervous system.
Which of the following neurotransmitters should the nurse include in the teaching as having an inhibitory action?
Serotonin
GABA
Acetylcholine
Dopamine
Dopamine
The Correct Answer is B
Choice A rationale
Serotonin is indeed an inhibitory neurotransmitter. It helps regulate mood, appetite, and sleep among other things. However, its role in the nervous system is complex and it can also have excitatory effects depending on the specific receptors and neural pathways involved.
Choice B rationale
Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the brain. It works by decreasing neuronal excitability, which helps to regulate muscle tone, among other functions.
Choice C rationale
Acetylcholine is primarily an excitatory neurotransmitter, although it can have inhibitory effects in certain parts of the nervous system. It plays a key role in muscle activation, learning, and memory.
Choice D rationale
Dopamine can act as both an inhibitory and an excitatory neurotransmitter, depending on the type of receptor it binds to and the specific neural pathway involved. It plays key roles in reward, motivation, and motor control.

Correct Answer is B
Explanation
Choice A rationale
While traumatic brain injuries (TBIs) can occur at any age, people in their 30s are not at the highest risk. Other factors, such as participation in high-risk activities or certain occupations, can increase the risk of TBI, but age alone in this group does not confer a higher risk.
Choice B rationale
People who play contact sports are at a higher risk of sustaining a TBI. Contact sports such as football, boxing, and hockey have a high incidence of TBIs, including concussions.
Choice C rationale
Abstaining from alcohol does not increase the risk of TBI. In fact, alcohol use is a risk factor for TBI, as it can increase the likelihood of falls, car accidents, and other events that can cause TBI1112.
Choice D rationale
Living in rural areas does not inherently increase the risk of TBI. However, certain factors associated with rural living, such as increased travel distances and limited access to trauma
care, can contribute to the severity of a TBI once it occurs. Subarachnoid hemorrhageSubarachnoid hemorrhage Explore
Correct Answer is C
Explanation
Choice A rationale
Trigeminal neuralgia is a chronic pain condition that affects the trigeminal nerve, which carries sensation from your face to your brain. It does not cause a sensation of tightness around the torso.
Choice B rationale
Lhermitte’s sign is a symptom of multiple sclerosis and other neurological conditions where a person feels an electric shock-like sensation running down the spine and into the limbs. It does not cause a sensation of tightness around the torso.
Choice C rationale
The sensation of tightness around the torso in a patient with multiple sclerosis is often referred to as the “MS hug”. It is caused by a lesion or an area of active inflammation within the spinal cord.
Choice D rationale
Paroxysmal spasms are a type of muscle spasm experienced by some people with multiple sclerosis. These spasms are usually painful and involve the muscles of the legs, but they do not cause a sensation of tightness around the torso.
