A nurse receives a report on a client with a basilar skull fracture. What findings should the nurse expect with this client?

Choice A rationale
Vision loss and depression are not typically symptoms of a mild traumatic brain injury (TBI). Vision loss could be a symptom of a more severe TBI or other neurological conditions.
Depression, while it can occur following a TBI, is not a direct symptom of the injury itself but rather a common psychological reaction to the changes and challenges that a person may face following the injury.
Choice B rationale

Seizures and weakness in the extremities can be symptoms of a TBI, but they are more commonly associated with moderate to severe TBIs. Mild TBIs do not typically cause seizures or weakness in the extremities.
Choice C rationale
Persistent headache can be a symptom of a mild TBI. However, aggressive behavior, while it can occur following a TBI, is not a direct symptom of the injury itself but rather a possible psychological reaction to the changes and challenges that a person may face following the injury.
Choice D rationale
Headache and confusion are common symptoms of a mild TBI. After a mild TBI, individuals may experience a headache or a feeling of pressure in the head. They may also experience confusion or feel as if in a fog.

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.
