NCLEX Questions for Neurological System Questions
Question 1 of 5
Which of the following is NOT a common symptom of Encephalitis which refers to infections that cause an inflammation of the brain resulting from the direct infection of the brain by a virus:
Correct Answer: A
Rationale: Encephalitis is an inflammation of the brain typically caused by viral infections. Common symptoms include fever, headache, confusion, seizures, and cognitive impairments. While irritability can occur, it is not as specific or common as other symptoms like seizures or delirium. Encephalitis can lead to severe neurological complications if not treated promptly, making early diagnosis and intervention critical.
Question 2 of 5
The action potential pattern that appears on the oscilloscope screen is caused by rapid ________.
Correct Answer: A
Rationale: The action potential pattern observed on an oscilloscope is caused by rapid changes in membrane polarity. During an action potential, the membrane potential depolarizes (becomes more positive) as sodium ions rush into the neuron, followed by repolarization (returning to negative) as potassium ions exit. These polarity changes are essential for the propagation of nerve impulses and are a hallmark of neural activity.
Question 3 of 5
The job of the Nervous System is:
Correct Answer: D
Rationale: The nervous system performs three primary functions: receiving sensory input, integrating and processing this input, and triggering motor responses. Sensory input involves detecting stimuli from the environment or within the body. Integration occurs in the brain and spinal cord, where information is processed. Motor output involves sending signals to muscles or glands to produce a response. Therefore, the nervous system's job encompasses all these functions, making 'All of the above' the correct answer.
Question 4 of 5
Each cerebral hemisphere is divided into ________ lobes, ________ of which have the same name as the bone over them.
Correct Answer: A
Rationale: Each cerebral hemisphere is divided into four lobes: the frontal, parietal, temporal, and occipital lobes. Three of these lobes (frontal, parietal, and temporal) share their names with the bones of the skull that overlie them. The occipital lobe is named after the occipital bone. Therefore, four, three is the correct answer as it accurately describes the division and naming of the cerebral lobes.
Question 5 of 5
Immediately after an action potential is propagated, which one of the following ions rapidly diffuses out of the cell into the tissue fluid:
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
