Question 73

Hemolysis occurs due to excessive shaking of a tube.

Excessive shaking of a tube can lead to hemolysis, which is the destruction of red blood cells resulting in the release of hemoglobin into the plasma. This can affect laboratory test results and lead to inaccurate diagnoses.

A) Hemophilia

Hemophilia is a genetic disorder that affects the blood's ability to clot, leading to prolonged bleeding. It is not caused by shaking a tube; instead, it is related to deficiencies in specific clotting factors. Therefore, this option is incorrect.

B) Hemoconcentration

Hemoconcentration refers to an increase in the concentration of blood components, typically caused by dehydration or fluid loss, not by shaking a tube. This option does not relate to the mechanical action described in the question, making it incorrect.

C) Hemolysis

Hemolysis is indeed caused by excessive shaking of a tube, as this mechanical agitation can disrupt red blood cells, leading to their rupture. This option correctly identifies the consequence of improper handling of blood samples.

D) Hemostasis

Hemostasis is the process that prevents and stops bleeding, involving clot formation. It is the opposite of what occurs during hemolysis and is not influenced by shaking a tube. Thus, this option is incorrect.

Conclusion

Hemolysis is the only option that directly correlates with the excessive shaking of a tube, as it results in the breakdown of red blood cells. All other options, including hemophilia, hemoconcentration, and hemostasis, pertain to different physiological processes and do not arise from the action described in the question.
