NCLEX Questions on Neurological System Questions
Question 1 of 5
The limbic system includes the:
Correct Answer: A
Rationale: The limbic system is a group of brain structures involved in emotion, memory, and motivation. It includes the amygdala, which processes fear and emotional responses; the hypothalamus, which regulates hormones and homeostasis; and the hippocampus, which is essential for forming and retrieving memories. These structures work together to integrate emotional and cognitive processes, playing a key role in behavior and survival.
Question 2 of 5
One of the most common features of neurological disorders are Language deficits and are collectively known as
Correct Answer: D
Rationale: Aphasia is a language disorder resulting from damage to the brain's language centers, typically in the left hemisphere. It affects the ability to produce or comprehend speech, read, or write. Aphasia can manifest in various forms, such as Broca's aphasia (difficulty speaking) or Wernicke's aphasia (difficulty understanding language). These deficits are common in neurological disorders like stroke, traumatic brain injury, or neurodegenerative diseases.
Question 3 of 5
Meningitis refers to that class of infections that cause inflammation of the meninges. Which Part of the brain does this refer to?
Correct Answer: B
Rationale: Meningitis is an infection that causes inflammation of the meninges, the protective membranes covering the brain and spinal cord. Symptoms include fever, headache, neck stiffness, and cognitive impairments. The inflammation can lead to serious complications, such as brain damage or sepsis, if not treated promptly. Meningitis can be caused by bacterial, viral, or fungal infections, with bacterial meningitis being the most severe form.
Question 4 of 5
A dendrite conducts nerve impulses ________ the cell body.
Correct Answer: B
Rationale: Dendrites are specialized structures that receive nerve impulses from other neurons and conduct them toward the cell body. They are branched extensions that increase the surface area for receiving signals. The electrical signals generated by neurotransmitters binding to receptors on dendrites travel toward the cell body, where they are integrated to determine whether the neuron will fire an action potential. This directional flow is essential for neural communication.
Question 5 of 5
The action potential is measured in millivolts (mV) and is ranged from:
Correct Answer: C
Rationale: The action potential involves a rapid change in membrane potential, typically ranging from -65mV (resting potential) to +40mV (peak depolarization). This change is driven by the influx of sodium ions and the subsequent efflux of potassium ions. The action potential is a key mechanism for transmitting information within the nervous system, enabling neurons to communicate over long distances.
