What is the most common consequence of myelosuppression?

1. Dehydration

2. Prone to infections

3. Weight loss

4. Enhanced healing process

The correct answer is: Prone to infections

Myelosuppression, a common side effect of chemotherapy and biotherapy, refers to the decreased production of blood cells due to the suppression of bone marrow activity. The correct answer points to the increased susceptibility to infections as the most significant consequence of this condition. This occurs because myelosuppression typically leads to a reduction in the number of white blood cells (WBCs), particularly neutrophils, which play a critical role in the immune response. A lower WBC count leaves the body less equipped to fight off pathogens, making patients more prone to infections. In contrast, dehydration, weight loss, and enhanced healing processes are not direct consequences of myelosuppression. While dehydration may occur due to other factors, it is not intrinsically linked to bone marrow function. Weight loss could be related to various issues, including nutritional deficiencies or disease progression, rather than a direct result of myelosuppression. Finally, myelosuppression does not enhance the healing process; rather, it typically impairs the body's ability to recover from infections and injuries due to a compromised immune system.
