b) Excess ADH secretion
c) Low sodium intake
d) Hypothyroidism
5. What causes the edema that occurs during the inflammatory process?
a) Reduced lymphatic drainage
b) Increased vascular permeability leading to fluid leakage into interstitial spaces
c) Decreased osmotic pressure in the vasculature
d) Reduced blood flow to inflamed tissue
6. Which of the following best describes Klinefelter syndrome?
a) A single X chromosome resulting in XO
b) An extra Y chromosome in males
c) An extra X chromosome in males (XXY), often leading to gynecomastia, small
testes, and sparse body hair
d) A deletion on chromosome 21
7. Alpha thalassemia is caused by:
a) Point mutation in beta-globin genes
b) Deletion of alpha-globin genes resulting in reduced hemoglobin production
c) Increased synthesis of fetal hemoglobin
d) Autoimmune destruction of red blood cells
8. Which of the following correctly describes the blood flow of the heart?
a) Right atrium → left ventricle → pulmonary artery → lungs → left atrium →
aorta
b) Right atrium → right ventricle → pulmonary artery → lungs → left atrium → left
ventricle → aorta
,c) Left atrium → left ventricle → pulmonary vein → lungs → right atrium → aorta
d) Right atrium → pulmonary vein → left atrium → left ventricle → aorta
9. During diastole, the heart is:
a) Contracting and ejecting blood into systemic circulation
b) Relaxed, allowing the ventricles to fill with blood from the atria
c) Undergoing rapid depolarization
d) Generating high systemic pressure
10. What occurs during systole?
a) The atria contract, pushing blood into the ventricles
b) The ventricles contract, pushing blood into the pulmonary artery and aorta
c) The semilunar valves close and blood passively fills the atria
d) The atria relax, reducing venous return
11. The QRS complex on an ECG represents:
a) Atrial depolarization
b) Atrial repolarization and ventricular depolarization
c) Ventricular repolarization
d) SA node activity
12. Atherosclerosis contributes to aneurysm formation because:
a) It increases blood viscosity
b) It increases contractility of the vessel wall
c) It erodes and weakens the vessel wall through plaque buildup
d) It decreases intravascular pressure
, 13. Which lipoprotein is associated with increased cardiovascular disease risk?
a) HDL > 60 mg/dL
b) LDL > 100 mg/dL
c) Triglycerides < 150 mg/dL
d) VLDL < 30 mg/dL
14. Which factor contributes most to myocardial hypertrophy in hypertension?
a) Angiotensin II
b) Elevated cortisol
c) Increased ADH
d) Excess insulin
What does aldosterone regulate? - ANSWER re-absorption of sodium and
water (indirectly excretion of potassium)
What causes the edema that occurs during the inflammatory process? - ANSWER
Increased vascular permeability. Increased pressure in the vasculature
secondary to the vasodilatory effects of inflammation result in leakage of fluid into
3rd spaces
Klinefelter syndrome - ANSWER A chromosomal disorder in which males have
an extra X chromosome, making them XXY instead of XY.
High pitched voice
