WGU D236 PATHO QUESTIONS AND ANSWERSTurner syndrome - Answers -A chromosomal disorder in females in which either an *X
chromosome* is missing, making the person XO instead of XX, or part of one X
chromosome is deleted.
Tay-Sachs Disease - Answers -A human genetic disease caused by a recessive allele
for a dysfunctional enzyme leads to the accumulation of certain lipids in the brain.
Seizures, blindness, and degeneration of motor and mental performance usually
become manifest a few months after birth, followed by death within a few years.
Down syndrome - Answers -A condition of mild to severe intellectual disability and
associated physical disorders caused by an extra copy of chromosome 21
Diabetes Insipidus - Answers -Antidiuretic hormone is not secreted adequately, or the
kidney is resistant to its effect. The *serum sodium is often elevated* due to excess free
water losses.
In diabetes insipidus, your blood glucose levels are normal, but your kidneys can't
properly concentrate urine.
Cardiac Valve Disease Process - Answers -In heart valve disease, one or more of the
valves in your heart doesn't work properly. Regurgitation (or leakage of the valve).
When the valve(s) do not close completely, it causes blood to flow backward through
the valve. This reduces forward blood flow and can lead to volume overload in the heart.
Stenosis (or narrowing of the valve). When the valve(s) opening becomes narrowed, it
limits the flow of blood out of the ventricles or atria. The heart is forced to pump blood
with increased force to move blood through the narrowed or stiff (stenotic) valve(s).
Cardiac Valve Complications - Answers -Heart valve disease can cause many
complications, including:
* Heart failure.
* Stroke.
* Blood clots.
* Heart rhythm abnormalities.
* Death.
Respiratory Illness from bats - Answers -*Viral hemorrhagic fevers* are spread by
contact with infected animals or insects. The viruses that cause viral hemorrhagic fevers

Most commonly, the hosts include mosquitoes, ticks, rodents, or bats. Some viral
hemorrhagic fevers can also be spread from person to person.

Ulcerative colitis - Answers -Ulcerative colitis is an *autoimmune disease of the large
intestine*, specifically the *colon and rectum*.
It affects the mucosal layer of the large intestine.
#Aortic stenosis/regurgitation
#Mitral stenosis/regurgitation - Answers -*Mitral valve stenosis* occurs when the mitral
valve in the heart narrows, restricting blood flow into the main pumping chamber. The
mitral valve may also leak, causing *blood to flow back through the valve each time the
left ventricle contracts*. This condition is called mitral valve regurgitation.
*Backflow of blood* is caused by failure of the heart's mitral valve to close tightly.
*Mitral valve regurgitation* is a condition in which the heart's mitral valve does not close
tightly, which allows *blood to flow backward in the heart*.
How could the provider distinguish ulcerative colitis from Crohn disease? - Answers -
*Ulcerative colitis only affects the large intestine*, while *Crohn's disease can affect the
