Question

A 67-year-old man is diagnosed with cancer and subsequently undergoes chemotherapy. As an expected side effect of chemotherapy, his bone marrow stops functioning. What is a potential consequence of this loss of function? A. His potassium levels will increase. B. His calcium levels will decrease. C. He'll suffer bone fractures even after minor trauma. D. He'll have inadequate levels of blood cells.

Answer 1

D.) He'll have inadequate levels of  blood cells, like red blood cells, white blood cells, and platelets. Additionally, bleeding, bruising, and several varieties of anemia as well as a potentially severely crippled immune system. 

Answer 2

The correct option is D.
The bone marrow cells are the cells that are responsible for production of red blood cells in the human body. If the cells stop functioning as a result of chemotherapy, the patient will have less blood in his body than he required since the cells producing the blood had been destroyed.
