WGU D220 PRACTICE QUESTIONS
• types of burns
Answer: Superficial (1st degree) - red/painfulPartial-thickness (2nd degree) -
wet/pink/painful Full-thickness (3rd degree) -white/swollen/no pain
• Viltigo
Answer: localized loss of skin pigmentation characterized by milk-whitepatches
• ischemic CVA vs hemorrhagic CVA
Answer: ischemic - clot vs hemorrhagic – blood
• subdural hematoma
Answer: collection of blood under the dura mater
• Alzheimer's disease vs parkinson's disease
Answer:
Alz - affects language andmemory
Park - affects all executive functioning
• Huntington's disease
Answer: Genetic disorder that causes progressive deteriorationof brain cells. caused
by a dominant allele. symptoms do not appear until about theage of 30. involves
involuntary muscle movement
• Sclerosis
Answer: abnormal condition of hardening
• disorders that cause vision loss
Answer: glaucoma - loss of pheripheral vision,cataracts - cloudy vision, retinal
detachment - floaters, flashes, curtain vision
• kyphosis
Answer: excessive outward curvature of the spine, causing hunching of theback.
,• disorders that cause hearing loss
Answer: Meniere's disease - changes in fluid intube of inner ear (imbalance and
vertigo), Otitis media - middle ear infection
• Predisposing factors of ischemic stroke
Answer:
-atrial fibrillation
-carotid stenosis
-cerebral arteriosclerosis
• rheumatoid arthritis
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
Answer: the bruising of brain tissue as the result of a head injurythat causes the
brain to bounce against the rigid bone of the skull; symptoms: ringing in ears,
severe headache, n/v.
• TIA vs CVA
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
Answer: A chronic, irreversible disease of the central nervous system marked by
damage to the myelin sheath. Plaques occur in the brain and spinalcord causing
tremor, weakness, incoordination, paresthesia, and disturbances invision and speech
• aneurysm
Answer: ballooning of a weakened portion of an arterial wall
, • thrombus vs embolus
Answer: Thrombus = clot in arteries embolus = dislodged traveling clot in arteries,
blocks blood flow
• Artherosclerosis
Answer: Hardening and narrowing of the arteries due to buildup ofcholesterol
plaques
1.endothelial injury
2.foam cell formation
3.fatty streak formation
• angina pectoris
Answer: chest pain, which may radiate to the left arm and jaw, thatoccurs when
there is an insufficient supply of blood to the heart muscle
• myocardial infarction
Answer: the occlusion of one or more coronary arteries causedby plaque buildup
(heart attack)
• endocarditis
Answer: inflammation of the inner lining of the heart
• peridcarditis
Answer: inflammation of the pericardium (sack surrounding heart)
• benign vs malignant hypertension
Answer: benign - "essential hypertension", chronic vascular damage due to sodium
retention.
malignant - acute vascular damage due to renin release
• communicable disease
Answer: A disease that can be spread from one person orspecies to another.
• infectious disease
Answer: A disease that is caused by a pathogen and that can bespread from one
individual to another.
