Autonomic Nervous System NCLEX Questions Questions
Question 1 of 5
An elderly client has suffered a brainstem hemorrhage. The nurse is aware that the brainstem controls which of the following functions?
Correct Answer: C
Rationale: The brainstem (e.g., medulla) regulates vital functions like blood pressure. Endocrine function is hypothalamic, sleep involves multiple areas, language is cortical.
Question 2 of 5
Clusters of neuron cell bodies embedded in the white matter of the brain are referred to as:
Correct Answer: A
Rationale: In the CNS, clusters of neuron cell bodies are called nuclei (e.g., basal nuclei). Gyri are cortical ridges, ganglia are PNS neuron clusters, and fasciculi are axon bundles.
Question 3 of 5
Which of the following is not involved with motor impulses or motor coordination?
Correct Answer: D
Rationale: All listed structures are involved in motor functions: red nucleus (midbrain motor relay), cerebellum (coordination), basal ganglia (movement refinement), precentral gyrus (primary motor cortex). 'None of the above' is incorrect.
Question 4 of 5
Cerebrospinal fluid (CSF) is found within:
Correct Answer: D
Rationale: CSF circulates in the ventricles, central canal of the spinal cord, and subarachnoid space, cushioning the CNS. The epidural space and dural sinuses do not normally contain CSF.
Question 5 of 5
The terminal portion of the spinal cord is known as the:
Correct Answer: B
Rationale: The conus medullaris is the tapered, terminal end of the spinal cord (around L1-L2). The cauda equina is nerve roots below it, and the filum terminale is a fibrous extension.
