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. - CORRECT ANSWER Turner syndrome
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. -
CORRECT ANSWER Tay-Sachs Disease
A condition of mild to severe intellectual disability and associated physical
disorders caused by an extra copy of chromosome 21 - CORRECT ANSWER Down
syndrome
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. - CORRECT ANSWER Diabetes Insipidus
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). - CORRECT ANSWER Cardiac Valve Disease Process
Heart valve disease can cause many complications, including:
* Heart failure.
* Stroke.
* Blood clots.
* Heart rhythm abnormalities.
* Death. - CORRECT ANSWER Cardiac Valve Complications
*Viral hemorrhagic fevers* are spread by contact with infected animals or insects.
The viruses that cause viral hemorrhagic fevers live in a variety of animal and
insect hosts.
Most commonly, the hosts include mosquitoes, ticks, rodents, or bats. Some viral
hemorrhagic fevers can also be spread from person to person. - CORRECT
ANSWER Respiratory Illness from bats
Different types of anemia include:
Anemia due to vitamin B12 deficiency
Anemia due to folate (folic acid) deficiency
, Anemia due to iron deficiency
Anemia of chronic disease
Hemolytic anemia
Idiopathic aplastic anemia
Megaloblastic anemia
Pernicious anemia
Sickle cell anemia
Thalassemia - CORRECT ANSWER Anemia
The kidneys have two main ways to maintain acid-base balance - their cells
reabsorb bicarbonate HCO3− from the urine back to the blood and they secrete
hydrogen H+ ions into the urine.
By adjusting the amounts reabsorbed and secreted, they balance the
bloodstream's ph. - CORRECT ANSWER Acid Base Balance - lung and kidney
compensation
Inflammation of the renal pelvis and the kidney - CORRECT ANSWER
Pyelonephritis
Cancer of the prostate gland usually occurs in men middle-aged and older. -
CORRECT ANSWER Prostate cancer
*Vasoconstriction* - CORRECT ANSWER Artery response during blood loss.
