NCLEX Questions on Neurological System Questions
Question 1 of 5
Loss of muscle coordination results from damage to the:
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
In the development of the nervous system, which is the correct order of events?
Correct Answer: B
Rationale: The correct sequence of nervous system development involves: (1) specification of cells as neurons, (2) migration of neurons to their final positions, (3) formation of connections with targets, and (4) refinement of synaptic connections. This order ensures proper neural circuit formation and function. Specification occurs first, followed by migration, which positions neurons correctly. Axon outgrowth and target connection occur next, and finally, synaptic pruning and refinement optimize neural communication.
Question 3 of 5
A client with a subdural hematoma becomes restless and confused, with dilation of the ipsilateral pupil. The physician orders mannitol for which of the following reasons?
Correct Answer: C
Rationale: Mannitol is an osmotic diuretic that draws fluid from the brain tissue into the vascular system, reducing intracranial pressure (ICP). This is critical in cases of subdural hematoma, where increased ICP can lead to brain herniation and further neurological damage. The drug works by creating an osmotic gradient, pulling water from the extracellular space of the brain into the bloodstream, which is then excreted by the kidneys. This mechanism helps alleviate symptoms like restlessness, confusion, and pupil dilation caused by increased ICP.
Question 4 of 5
The nurse is caring for a client with ICP. Why will the nurse position the client in bed with HOB elevated to 30 degrees?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
The nurse notes that a patient is not able to voluntarily move the right arm. Which part of the brain should the nurse suspect is affected in this patient?
Correct Answer: B
Rationale: The frontal lobes contain the motor areas that generate the impulses that bring about voluntary movement. Each motor area controls movement on the opposite side of the body. The cerebellum is responsible for coordination and balance, while the parietal lobe processes sensory information. The hypothalamus regulates autonomic functions and is not directly involved in voluntary movement.
