Question
What are the two main parts of the nervous system?

A) Somatic and autonomic
B) Central and peripheral
C) Sympathetic and parasympathetic
D) Brain and spinal cord

Expert Rationale: The nervous system is divided into the central nervous system (brain and
spinal cord) and the peripheral nervous system (cranial nerves, spinal nerves, and
autonomic nervous system). The somatic and autonomic divisions are part of the
peripheral nervous system.



Question
A patient's wife reports personality changes, difficulty understanding, crying easily, and
anger. Which cerebral lobe is responsible for these behaviors?

A) Temporal
B) Parietal
C) Frontal
D) Occipital

Expert Rationale: The frontal lobe is responsible for personality, behavior, emotional
expression, and higher cognitive functions (judgment, reasoning, understanding). Damage
to the frontal lobe can cause personality changes, emotional lability, and impaired
understanding.

,Question
Which statement about the areas of the brain is true?

A) The hypothalamus controls body temperature and regulates sleep
B) The cerebellum controls personality and behavior
C) The occipital lobe controls motor function
D) The temporal lobe controls balance and coordination

Expert Rationale: The hypothalamus controls body temperature, sleep, appetite, and
autonomic functions. The cerebellum controls balance and coordination; the frontal lobe
controls personality and behavior; the occipital lobe controls vision.



Question
What area of the nervous system is responsible for mediating reflexes?

A) Brainstem
B) Spinal cord
C) Cerebellum
D) Peripheral nerves

Expert Rationale: The spinal cord mediates reflexes through reflex arcs, which are rapid,
involuntary responses to stimuli. Reflexes do not require input from the brain, although the
brain can modulate them.



Question
A nurse accidentally receives a needle prick. To interpret this sensation, which areas of the
nervous system must be intact?

A) Lateral spinothalamic tract, thalamus, and sensory cortex
B) Posterior columns, cerebellum, and brainstem
C) Corticospinal tract, basal ganglia, and cerebellum
D) Spinocerebellar tract, thalamus, and frontal lobe

Expert Rationale: Pain and temperature sensations are transmitted via the lateral
spinothalamic tract to the thalamus and then to the sensory cortex, where the sensation is
interpreted. The posterior columns carry vibration and position sense.

,Question
A patient with cardiac ischemia has pain in the chest and shoulder. What is the best
explanation for this?

A) The sensory cortex does not have the ability to localize pain in the heart; consequently,
the pain is felt elsewhere
B) The pain is caused by anxiety
C) The pain is referred from the lungs
D) The pain is caused by muscle strain

Expert Rationale: Referred pain occurs because the sensory cortex cannot precisely
localize pain from internal organs like the heart. Visceral pain fibers synapse on the same
second-order neurons as somatic pain fibers, causing the pain to be felt in the shoulder,
arm, or jaw.



Question
What controls humans' ability to perform very skilled movements such as writing?

A) Corticospinal tract
B) Spinothalamic tract
C) Posterior columns
D) Spinocerebellar tract

Expert Rationale: The corticospinal tract (pyramidal tract) controls voluntary, skilled
movements, especially of the distal extremities (hands and fingers). It originates in the
motor cortex and descends through the brainstem and spinal cord.



Question
A patient reports being very unsteady and having difficulty maintaining balance. Which area
of the brain is most concerning?

A) Frontal lobe
B) Cerebellum
C) Temporal lobe
D) Occipital lobe

Expert Rationale: The cerebellum is responsible for balance, coordination, and posture.
Dysfunction of the cerebellum causes ataxia, unsteadiness, and difficulty with
coordination.

, Question
Which statement about the peripheral nervous system is correct?

A) The peripheral nerves carry input to the CNS by afferent fibers and away from the CNS by
efferent fibers
B) The peripheral nervous system includes the brain and spinal cord
C) The peripheral nervous system has no role in sensation
D) The peripheral nervous system only controls voluntary movement

Expert Rationale: The peripheral nervous system carries sensory input to the central
nervous system (CNS) via afferent (sensory) fibers and motor output away from the CNS via
efferent (motor) fibers. It includes cranial and spinal nerves.



Question
A patient has a severed spinal nerve from trauma. Which statement is true?

A) The adjacent spinal nerves will continue to carry most of the sensations for the
dermatome served by the severed nerve
B) There will be complete loss of sensation in the affected dermatome
C) The severed nerve will regenerate completely within 6 months
D) Motor function will be unaffected

Expert Rationale: Adjacent spinal nerves overlap in their innervation of dermatomes, so if
one spinal nerve is severed, the adjacent nerves can often continue to carry most of the
sensations for that dermatome. There may be some sensory loss, but it is usually not
complete.



Question
A patient has a head injury and is unconscious with no other injuries. What would the nurse
expect when testing deep tendon reflexes?

A) Reflexes will be normal
B) Reflexes will be absent
C) Reflexes will be hyperactive
D) Reflexes will be diminished
