Correct Answer: C

Rationale: Monitoring hemoglobin and hematocrit is essential to assess the effectiveness of ruxolitinib in treating myelofibrosis. Ruxolitinib works by inhibiting JAK1 and JAK2, which are involved in the signaling pathways that regulate blood cell production. Therefore, monitoring hemoglobin and hematocrit levels can provide valuable information on how well the drug is managing the disease. Blood pressure, white blood cell count, and spleen size are not direct indicators of the treatment's effectiveness in myelofibrosis.

Brachytherapy involves placing radioactive sources inside or near the tumor, delivering a high radiation dose to the targeted area while minimizing exposure to surrounding healthy tissues.

Choice D is incorrect as feces is not a source of radiation in teletherapy, and it does not require special disposal.
