A nurse is caring for a client who has sleep dysregulation, poor memory, and poor concentration. When collecting data, which of the following neurotransmitters should the nurse identify as being responsible for the client's manifestations?

Serotonin

Histamine

Dopamine

Norepinephrine

Answer and Explanation

The Correct Answer is A

A. Serotonin. Serotonin plays a crucial role in regulating sleep, memory, and concentration. Low serotonin levels are associated with sleep disturbances, cognitive impairments, and mood disorders such as depression, which can further exacerbate difficulties with memory and focus.
B. Histamine. Histamine primarily regulates wakefulness and alertness but is not the primary neurotransmitter involved in sleep dysregulation, memory, and concentration. While histamine imbalance can contribute to sleep disturbances, it is more commonly linked to allergic responses and arousal states.
C. Dopamine. Dopamine is involved in motivation, reward, and motor control. While dopamine dysfunction can lead to cognitive issues, it is more closely associated with disorders such as Parkinson’s disease and schizophrenia rather than sleep dysregulation and poor memory.
D. Norepinephrine. Norepinephrine is a key neurotransmitter in the body's stress response and alertness regulation. While it influences attention and arousal, its dysregulation is more commonly linked to anxiety and hypervigilance rather than the described symptoms.

Correct Answer is C

Explanation

A. Severe restlessness. Severe restlessness, known as akathisia, is a potential side effect of antipsychotic medications but is not indicative of agranulocytosis. Akathisia is associated with excessive movement and an inability to stay still, often requiring dose adjustment or medication to alleviate symptoms.
B. Respiratory depression and a comatose state. Respiratory depression and coma are not linked to agranulocytosis but may occur with overdose or central nervous system depression. Agranulocytosis affects white blood cell levels, leading to increased infection risk rather than sedation or respiratory suppression.
C. Sore throat and muscle aches. Sore throat and muscle aches are early signs of agranulocytosis, a potentially life-threatening condition characterized by a dangerously low neutrophil count. Clients taking clozapine must undergo regular white blood cell monitoring to detect agranulocytosis early and prevent severe infections.
D. Increased anxiety and suicidal ideations. Increased anxiety and suicidal ideations may be related to psychiatric conditions or medication effects but are not specific to agranulocytosis. Clozapine is primarily used for treatment-resistant schizophrenia and may help reduce suicidal behavior rather than induce it.

A. School-age B. Young adulthood C. Preschooler D. Older adulthood

Correct Answer is B

Explanation

A. School-age: Schizophrenia is rare in children, and early-onset cases before adolescence are uncommon. Symptoms that resemble schizophrenia in children often require further evaluation for other neurodevelopmental disorders.
B. Young adulthood: Schizophrenia typically manifests between late adolescence and early adulthood, usually between ages 18 and 25 in men and slightly later in women. This period is when individuals experience their first psychotic episode.
C. Preschooler: Schizophrenia is extremely rare in preschool-aged children. Symptoms such as hallucinations or disorganized behavior at this age are more likely related to other developmental disorders or trauma.
D. Older adulthood: Late-onset schizophrenia is rare, and when psychotic symptoms emerge in older adults, they are often due to conditions such as dementia, delirium, or medication effects rather than primary schizophrenia.
