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.

A. The patient should be the only one to control the PCA pump. This is to prevent overmedication and to ensure the patient is in control of their pain management.
B. While it's important to use the PCA responsibly, the device is designed to prevent overdose. It has built-in safeguards to limit the amount of medication delivered.
C. This statement indicates that the patient understands the importance of communicating with the nurse about pain management. If the PCA is not effectively controlling pain, the nurse needs to be notified to adjust the medication or explore other options.
