Question 1

It is imperative that the dental staff understand the cause of a cerebrovascular accident (CVA) so that they can provide the most appropriate emergency care.

Accepted Answer

False

Question 2

Unequal pupil size indicates that a patient may be experiencing a cerebrovascular accident (CVA).

Accepted Answer

Unequal pupil size, also known as anisocoria, can be a sign of a CVA, as well as other neurological conditions such as head trauma, brain tumor, or nerve damage. It is important to seek medical attention immediately if anisocoria is noticed.

Question 3

A transient ischemic attack (TIA) does not usually create an emergency situation in the dental office.

Accepted Answer

A transient ischemic attack (TIA) is a temporary interruption of blood flow to the brain, often referred to as a mini-stroke. While it is a serious medical condition that requires prompt evaluation and treatment, it does not usually create an emergency situation in the dental office. However, it is important to be aware of your patients' medical histories and any medications they may be taking, as these can increase their risk of a TIA or other medical emergency.

Question 4

A cerebrovascular accident (CVA) is also known as ____.&#10;A) a stroke&#10;B) dementia&#10;C) paralysis&#10;D) paresis

Accepted Answer

A cerebrovascular accident (CVA) is commonly referred to as a stroke.

Question 5

Which is generally NOT a sign or symptom of a cerebrovascular accident (CVA)?&#10;A) headache&#10;B) confusion&#10;C) slurred speech&#10;D) spastic movements

Accepted Answer

Spastic movements are not typically associated with a cerebrovascular accident (CVA). Common signs and symptoms of a CVA include headache, confusion, and slurred speech. However, spastic movements may occur with certain neurological conditions, such as cerebral palsy or multiple sclerosis.

Question 6

Many people who experience a transient ischemic attack (TIA) report feeling ____.&#10;A) &#34;pins-and-needles&#34;&#10;B) &#34;shooting pain&#34;&#10;C) &#34;hot flashes&#34;&#10;D) &#34;dull aches&#34;

Accepted Answer

Many people who experience a TIA report feeling "pins-and-needles." This is a common symptom of the neurological effects of a TIA.

Question 7

Which type of cerebrovascular accident (CVA) is characterized by a wandering clot that may become lodged in a cerebral artery?&#10;A) embolism&#10;B) infarction&#10;C) hemorrhage&#10;D) thrombosis

Accepted Answer

An embolism is a type of CVA in which a blood clot, also known as an embolus, wanders through the bloodstream before becoming lodged in a cerebral artery, blocking blood flow to the brain. This can lead to a stroke.

Question 8

What is a common cause of a cerebral hemorrhage?&#10;A) venous blood clot&#10;B) arterial blood clot&#10;C) ruptured aneurysm&#10;D) atherosclerosis

Accepted Answer

A cerebral hemorrhage is typically caused by a ruptured aneurysm, which is a weak or thin spot on a blood vessel in the brain that has ruptured and caused bleeding into the brain tissue. Venous or arterial blood clots and atherosclerosis are more commonly associated with ischemic strokes.

Question 9

A cerebral ____ results from the disruption of arterial blood supplied from the heart to the brain.&#10;A) embolism&#10;B) infarction&#10;C) hemorrhage&#10;D) thrombosis

Accepted Answer

An infarction is a type of stroke that occurs when an artery supplying blood to the brain is blocked, leading to death of brain tissue due to lack of oxygen and nutrients. This can be caused by a clot (thrombosis) or a traveling clot (embolism) that becomes lodged in an artery. A hemorrhage, on the other hand, occurs when a blood vessel in the brain ruptures, leading to bleeding and damage to brain tissue.

Question 10
