27. Which of the following conditions results from exceeding the maximum blood volume parameter during blood collection?
Answer: A
Iatrogenic anemia results from exceeding the maximum blood volume parameter during blood collection.
Iatrogenic anemia occurs when a patient experiences a decrease in red blood cells due to medical interventions, such as excessive blood draws. This condition is directly linked to surpassing the recommended blood volume limits during collection procedures.
A) Iatrogenic anemia
This option is correct because iatrogenic anemia specifically arises when the amount of blood drawn exceeds safe limits, leading to a reduction in the patient's red blood cell count. The condition highlights the importance of adhering to blood volume guidelines to prevent adverse effects on the patient's health.
B) Hemolytic anemia
Hemolytic anemia is characterized by the premature destruction of red blood cells, which can occur due to various causes such as autoimmune disorders or infections. However, it is not directly related to the volume of blood collected, making this option incorrect in the context of the question.
C) Pernicious anemia
Pernicious anemia is a type of megaloblastic anemia caused by the inability to absorb vitamin B12 due to intrinsic factor deficiency. It is not associated with blood collection practices and therefore does not relate to exceeding blood volume parameters, rendering this option incorrect.
D) Sideroblastic anemia
Sideroblastic anemia is a condition where the bone marrow produces ringed sideroblasts instead of healthy red blood cells, often due to genetic factors or exposure to toxins. This condition is unrelated to blood collection volumes, making this option incorrect as well.
Conclusion
Iatrogenic anemia is the only condition among the options listed that directly results from exceeding the maximum blood volume parameter during blood collection. The other options, while related to different forms of anemia, do not stem from blood collection practices and thus do not apply in this context. Adhering to blood volume limits is crucial to prevent iatrogenic anemia and ensure patient safety during medical procedures.
