Chapter 23: Neurologic System
Jarvis: Physical Examination & Health Assessment, 7th Edition
MULTIPLE CHOICE
1.   The two parts of the nervous system are the:
a.

Motor and sensory.

b.

Central and peripheral.

c.

Peripheral and autonomic.

d.

Hypothalamus and cerebral.

2.   The wife of a 65-year-old man tells the nurse that she is concerned because she has noticed a change in her husband’s personality and ability to understand. He also cries very easily and becomes angry. The nurse recalls that the cerebral lobe responsible for these behaviors is the __________ lobe.
a.

Frontal

b.

Parietal

c.

Occipital

d.

Temporal

 3.   Which statement concerning the areas of the brain is true?
a.

The cerebellum is the center for speech and emotions.

b.

The hypothalamus controls body temperature and regulates sleep.

c.

The basal ganglia are responsible for controlling voluntary movements.

d.

Motor pathways of the spinal cord and brainstem synapse in the thalamus.

  4.   The area of the nervous system that is responsible for mediating reflexes is the:
a.

Medulla.

b.

Cerebellum.

c.

Spinal cord.

d.

Cerebral cortex.

 5.   While gathering equipment after an injection, a nurse accidentally received a prick from an improperly capped needle. To interpret this sensation, which of these areas must be intact?
a.

Corticospinal tract, medulla, and basal ganglia

b.

Pyramidal tract, hypothalamus, and sensory cortex

c.

Lateral spinothalamic tract, thalamus, and sensory cortex

d.

Anterior spinothalamic tract, basal ganglia, and sensory cortex

 6.   A patient with a lack of oxygen to his heart will have pain in his chest and possibly in the shoulder, arms, or jaw. The nurse knows that the bestexplanation why this occurs is which one of these statements?
a.

A problem exists with the sensory cortex and its ability to discriminate the location.

b.

The lack of oxygen in his heart has resulted in decreased amount of oxygen to the areas experiencing the pain.

c.

The sensory cortex does not have the ability to localize pain in the heart; consequently, the pain is felt elsewhere.

d.

A lesion has developed in the dorsal root, which is preventing the sensation from being transmitted normally.

  7.   The ability that humans have to perform very skilled movements such as writing is controlled by the:
a.

Basal ganglia.

b.

Corticospinal tract.

c.

Spinothalamic tract.

d.

Extrapyramidal tract.

  8.   A 30-year-old woman tells the nurse that she has been very unsteady and has had difficulty in maintaining her balance. Which area of the brain that is related to these findings would concern the nurse?
a.

Thalamus

b.

Brainstem

c.

Cerebellum

d.

Extrapyramidal tract

  9.   Which of these statements about the peripheral nervous system is correct?
a.

The CNs enter the brain through the spinal cord.

b.

Efferent fibers carry sensory input to the central nervous system through the spinal cord.

c.

The peripheral nerves are inside the central nervous system and carry impulses through their motor fibers.

d.

The peripheral nerves carry input to the central nervous system by afferent fibers and away from the central nervous system by efferent fibers.

 10.   A patient has a severed spinal nerve as a result of trauma. Which statement is true in this situation?
a.

Because there are 31 pairs of spinal nerves, no effect results if only one nerve is severed.

b.

The dermatome served by this nerve will no longer experience any sensation.

c.

The adjacent spinal nerves will continue to carry sensations for the dermatome served by the severed nerve.

d.

A severed spinal nerve will only affect motor function of the patient because spinal nerves have no sensory component.
