EXAM SCRIPT 2026 SOLVED QUESTIONS
WITH CORRECT ANSWERS GRADED A+
⩥ Tay-Sachs Disease.
Answer: 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.
Answer: A condition of mild to severe intellectual disability and
associated physical disorders caused by an extra copy of chromosome 21
⩥ Diabetes Insipidus.
Answer: 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.
Answer: 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.
Answer: Heart valve disease can cause many complications, including:
* Heart failure.
* Stroke.
* Blood clots.
* Heart rhythm abnormalities.
* Death.
⩥ Respiratory Illness from bats.
,Answer: *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.
⩥ Anemia.
Answer: 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
⩥ Acid Base Balance - lung and kidney compensation.
, Answer: 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.
⩥ Pyelonephritis.
Answer: Inflammation of the renal pelvis and the kidney
⩥ Prostate cancer.
Answer: Cancer of the prostate gland usually occurs in men middle-aged
and older.
⩥ Artery response during blood loss.
Does cell shrink or swell ?.
Answer: *Vasoconstriction*
⩥ Marfan Syndrome - Autosomal dominant trait.
Answer: This condition is inherited in an autosomal dominant pattern ,
which means one copy of the altered gene in each cell is sufficient to
cause the disorder.
