Neurological System NCLEX Questions Questions
Question 1 of 5
After a car accident, Rhodri had a lot of difficulty planning his day. This is most likely the result of damage to which lobe?
Correct Answer: C
Rationale: The frontal lobe is responsible for executive functions, such as planning, decision-making, and problem-solving. Damage to the frontal lobe, as might occur in a car accident, can impair these abilities, making it difficult for individuals to organize tasks, set goals, or manage time. The frontal lobe also plays a role in personality, social behavior, and motor control, highlighting its importance in complex cognitive processes.
Question 2 of 5
A fatal infectious disease known as: 'Mad cow disease' is medically known as:
Correct Answer: D
Rationale: Spongiform encephalopathy, commonly known as 'mad cow disease' or Variant Creutzfeldt-Jakob Disease (vCJD), is a fatal neurodegenerative disorder caused by abnormal prion proteins. These proteins induce the misfolding of normal cellular proteins in the brain, leading to brain damage and the characteristic spongy appearance of brain tissue. The disease is transmissible and has no known cure, making it a significant public health concern.
Question 3 of 5
Neuroglial cells support and provide nutrition for the ________.
Correct Answer: C
Rationale: Neuroglial cells, also known as glial cells, are non-neuronal cells that provide support and nutrition to neurons. They play essential roles in maintaining homeostasis, forming myelin sheaths, and protecting neurons from damage. Types of neuroglial cells include astrocytes, oligodendrocytes, microglia, and Schwann cells. These cells ensure the proper functioning of the nervous system by creating a supportive environment for neurons.
Question 4 of 5
A nerve fiber obeys an all-or-none law insofar as it either fires or does not fire depending on whether the stimulus is above a threshold.
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
The Peripheral Nervous System is made up of the:
Correct Answer: B
Rationale: The peripheral nervous system (PNS) includes all the nerves outside the central nervous system, such as spinal nerves and cranial nerves. It connects the CNS to the limbs, organs, and skin, allowing for the transmission of sensory and motor signals. The PNS is divided into the somatic nervous system, which controls voluntary movements, and the autonomic nervous system, which regulates involuntary functions like heart rate and digestion.
