COPD is known to cause decreased levels of Oxygen saturation in the blood. This chronic hypoxemia can lead to the body to compensate and produce more Red Blood Cells (RBCs) which increases the Hematocrit. This result is called:
Anemia
Hypoxic drive
Polycythemia
Pancytopenia
The Correct Answer is C
A. Anemia is a decrease in red blood cells, opposite to the condition described.
B. Hypoxic drive refers to the body's adaptation to use low oxygen levels as a stimulus to breathe, not an increase in red blood cells.
C. Polycythemia refers to an abnormal increase in red blood cells, which is a compensatory mechanism for chronic hypoxia.
D. Pancytopenia is a decrease in all types of blood cells, not an increase in one specific type.
