Neurological System NCLEX Questions Questions
Question 1 of 5
Preparing the body for "fight-or-flight" response during threatening situations is the role of the:
Correct Answer: A
Rationale: The sympathetic nervous system prepares the body for 'fight-or-flight' responses during threatening situations by increasing heart rate, dilating pupils, and redirecting blood flow. The parasympathetic nervous system has the opposite effect, while the cerebrum, somatic nervous system, and afferent nervous system are not primarily responsible for this response. Thus, A is the correct answer.
Question 2 of 5
The ventricular proliferative zone is:
Correct Answer: D
Rationale: The ventricular proliferative zone is a region of active cell division located in the neural tube. It gives rise to neurons and glial cells during nervous system development. This zone is essential for generating the vast number of cells required to form the complex structure of the brain and spinal cord.
Question 3 of 5
Which of the following signs and symptoms of increased ICP after head trauma would appear first?
Correct Answer: C
Rationale: Restlessness and confusion are often the earliest signs of increased ICP. These symptoms occur due to impaired cerebral perfusion and hypoxia. As ICP rises, it compresses brain tissue and blood vessels, leading to altered mental status. Bradycardia, widened pulse pressure, and changes in urine output are later signs of increased ICP and indicate more severe neurological compromise.
Question 4 of 5
A nurse is assessing a client who has returned from a cerebral arteriogram. The left carotid site was punctured. Which of the following indicates complications?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
The nurse is preparing material about impulse transmission to help with a presentation on the neurological system. When discussing spinal nerves, the nurse will include that each spinal nerve is made up of the dorsal root and which other root?
Correct Answer: C
Rationale: Each spinal nerve has two roots: the dorsal root, which carries sensory impulses into the spinal cord, and the ventral root, which carries motor impulses away from the spinal cord. The medial, lateral, and proximal roots are not part of the spinal nerve structure. Understanding this anatomy is essential for explaining how sensory and motor functions are integrated.
