Question 13

Hemolysis is caused by excessive shaking of a tube.

Excessive shaking of a tube can lead to hemolysis, which is the destruction of red blood cells, releasing hemoglobin into the surrounding fluid.

A) Hemophilia

Hemophilia is a genetic disorder that affects the blood's ability to clot properly due to deficiencies in clotting factors. It is not caused by excessive shaking of a tube; therefore, this option is incorrect.

B) Hemoconcentration

Hemoconcentration refers to an increase in the concentration of cells and solids in the blood due to a decrease in plasma volume. This condition is not directly related to the shaking of a tube, making this option incorrect as well.

C) Hemolysis

Hemolysis occurs when red blood cells are damaged or destroyed, which can occur from excessive shaking of a tube. This mechanical action can disrupt the cell membranes, leading to the release of hemoglobin and other intracellular components into the plasma, confirming this option as correct.

D) Hemostasis

Hemostasis is the process that prevents and stops bleeding, involving the clotting of blood. It is not affected by the shaking of a tube, thus rendering this option incorrect.

Conclusion

Hemolysis is the only condition among the options that directly results from excessive shaking of a tube, as it pertains to the mechanical disruption of red blood cells. The other options, including hemophilia, hemoconcentration, and hemostasis, are unrelated to the physical action of shaking, solidifying hemolysis as the definitive correct answer.
