A nurse is attending to a client with multiple sclerosis who reports a sensation of tightness around their torso. What condition should the nurse identify this symptom as indicating?

Choice A rationale
A patient reporting a burning sensation is a subjective sign of pain. It relies on the patient’s personal experience and verbal report.
Choice B rationale
A patient grimacing when they move is an objective sign of pain. It is observable and does not rely on the patient’s verbal report.
Choice C rationale

A patient rating their pain as an 8 on a scale of 0 to 10 is a subjective sign of pain. It relies on the patient’s personal experience and verbal report.
Choice D rationale
A patient stating the pain is located in their abdomen is a subjective sign of pain. It relies on the patient’s personal experience and verbal report.

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.
