EXAM SET WITH QUESTIONS AND VERIFIED
ANSWERS
disorders that cause hearing loss - correct-answer - Meniere's disease - changes in
fluid in tube of inner ear (imbalance and vertigo), Otitis media - middle ear
infection
Predisposing factors of ischemic stroke - correct-answer - a fib, carotid stenosis,
cerebral arteriosclerosis
rheumatoid arthritis - correct-answer - A chronic systemic disease characterized
by inflammation of the joints, stiffness, pain, and swelling that results in crippling
deformities. Causes elevated WBC counts.

cerebral contusion - correct-answer - the bruising of brain tissue as the result of a
head injury that causes the brain to bounce against the rigid bone of the skull;
symptoms: ringing in ears, severe headache, n/v.
TIA vs CVA - correct-answer - TIA =
-result when a cerebral artery is temp blocked and decreases blood flow to brain
Stroke= artery completely blocked
leading to death of brain and permanent loss of certain functions
multiple sclerosis - correct-answer - A chronic, irreversible disease of the central
nervous system marked by damage to the myelin sheath. Plaques occur in the
brain and spinal cord causing tremor, weakness, incoordination, paresthesia, and
disturbances in vision and speech
aneurysm - correct-answer - ballooning of a weakened portion of an arterial wall
,3|Page
thrombus vs embolus - correct-answer - Thrombus = clot in arteries
embolus = dislodged traveling clot in arteries, blocks blood flow
Artherosclerosis - correct-answer - Hardening and narrowing of the arteries due
to buildup of cholesterol plaques
1.endothelial injury
2.foam cell formation
3.fatty streak formation
angina pectoris - correct-answer - chest pain, which may radiate to the left arm
and jaw, that occurs when there is an insufficient supply of blood to the heart
muscle
, 4|Page
myocardial infarction - correct-answer - the occlusion of one or more coronary
arteries caused by plaque buildup (heart attack)
endocaritis - correct-answer - inflammation of the inner lining of the heart
peridcarditis - correct-answer - inflammation of the pericardium (sack
surrounding heart)
benign vs malignant hypertension - correct-answer - benign - "essential
hypertension", chronic vascular damage due to sodium retention.
malignant - acute vascular damage due to renin release
communicable disease - correct-answer - A disease that can be spread from one
person or species to another.
