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

Answer and Explanation

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 D

Explanation

Choice A rationale
Monitoring volume status is important in managing increased ICP, but it is not a direct intervention to reduce ICP78.
Choice B rationale

Ensuring proper ventriculostomy transducer levels is important in monitoring ICP, but it is not a direct intervention to reduce ICP78.
Choice C rationale
Managing sedation can help control agitation and excessive muscular activity, which can potentially increase ICP. However, it is not a direct intervention to reduce ICP78.
Choice D rationale
Elevating the head of the bed 15 degrees can help promote venous drainage, enhance cerebral perfusion, and reduce ICP78.

Choice C rationale
Maintaining systolic BP between 130 and 135 mm Hg is considered elevated and can increase the risk of stroke.
