NCLEX Questions for Neurological System Questions
Question 1 of 5
Testosterone is to ________ as estrogen is to ________.
Correct Answer: B
Rationale: Testosterone is primarily produced by the testes in males, while estrogen is primarily produced by the ovaries in females. Both hormones play crucial roles in reproductive development and function. Testosterone is associated with male secondary sexual characteristics, such as muscle mass and facial hair, while estrogen regulates the menstrual cycle and female secondary sexual characteristics. These hormones also have broader effects on mood, bone density, and overall health.
Question 2 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 3 of 5
Which of the following are the parts of neurons?
Correct Answer: B
Rationale: Neurons are the basic building blocks of the nervous system and consist of three main parts: dendrites, axons, and the cell body. Dendrites receive signals from other neurons, the cell body contains the nucleus and organelles, and the axon transmits signals to other neurons or target cells. These components work together to facilitate communication within the nervous system, enabling sensory perception, motor control, and cognitive functions.
Question 4 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 5 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.
