Question 1

An ascending spinal cord pathway:&#10;A) carries motor information to the periphery.&#10;B) carries information from the brain to the muscles.&#10;C) provides pathways for sensory information traveling from the periphery to the brain.&#10;D) provides pathways for motor information coming from the brain to the nerve endings.

Accepted Answer

The spinal cord provides pathways for sensory information traveling from the periphery to the brain.

Question 2

During a physical examination the doctor may tap the quadriceps ligament below your kneecap. Which reflex is he or she testing?&#10;A) patellar tendon reflex&#10;B) withdrawal reflex&#10;C) Babinski reflex&#10;D) pupillary reflex

Accepted Answer

During a physical examination, the doctor taps the quadriceps ligament below your kneecap. In response to the tap, your leg quickly and involuntarily pops up. The physician has elicited the patellar tendon reflex.

Question 3

This reflex helps your body maintain a normal blood pressure.&#10;A) Babinski reflex&#10;B) withdrawal reflex&#10;C) pupillary reflex&#10;D) baroreceptor

Accepted Answer

When blood pressure changes abruptly, the baroreceptor reflex causes the heart and blood vessels to respond in a way that restores blood pressure to normal.

Question 4

Which of the cranial nerves is labeled CN I?&#10;A) optic&#10;B) olfactory&#10;C) oculomotor&#10;D) vestibulocochlear

Accepted Answer

CN I, olfactory nerve. A sensory nerve that carries information from the nose to the olfactory areas of the temporal and parietal lobes of the cerebrum. The olfactory nerve is concerned with the sense of smell.

Question 5

Which of the cranial nerves is labeled CN X?&#10;A) vagus&#10;B) vestibulocochlear&#10;C) glossopharyngeal&#10;D) accessory

Accepted Answer

CN X, vagus nerve. A mixed nerve that innervates the tongue, pharynx (throat), larynx (voice box), and many organs in the thoracic and abdominal cavities (lungs, stomach, intestines).

Question 6

Which of the cranial nerves allows you to shrug your shoulders?&#10;A) oculomotor&#10;B) vagus&#10;C) hypoglossal&#10;D) accessory

Accepted Answer

CN XI, accessory nerve. Primarily a motor nerve that supplies the sternocleidomastoid and the trapezius muscles, thereby controlling movement of the head and shoulder regions.

Question 7

Damage to this nerve causes blindness.&#10;A) oculomotor&#10;B) optic&#10;C) abducens&#10;D) trochlear

Accepted Answer

Damage to the optic nerve causes diminished vision or blindness in the affected eye.

Question 8

Spinal nerves are grouped and sorted here.&#10;A) femoral&#10;B) common peroneal&#10;C) plexus(es)&#10;D) cauda equina

Accepted Answer

Each plexus sorts out the many fibers and sends them to a specific part of the body

Question 9

A student nurse is instructed to administer an intramuscular (IM) injection in the upper outer quadrant of the buttocks to:&#10;A) prevent ototoxicity.&#10;B) minimize systemic effects of the drug.&#10;C) avoid penetration of the subarachnoid space.&#10;D) avoid injury to the sciatic nerve.

Accepted Answer

The sciatic nerve can become inflamed and cause intense pain in the buttock and posterior thigh region.

Question 10

Which of the following is a true statement?&#10;A) The olfactory nerve is a motor nerve.&#10;B) The second cranial nerve is a sensory nerve.&#10;C) The phrenic, sciatic, and axillary nerves are cranial nerves.&#10;D) The vagus is confined to the cranium.

Accepted Answer

CN II, optic nerve. A sensory nerve that carries visual information from the eye to the primary visual cortex of the occipital lobe of the cerebrum.
