In providing care to a patient receiving chemotherapy for the treatment of colorectal cancer, the nurse correlates which mechanism of action to the prescribed 5-fluorouracil (5-FU) ?

A) This medication is cell-cycle specific and interferes with the synthesis of DNA and RNA, causing its death.
B) This medication is converted in the tissue to 5-FU, which inhibits DNA and RNA synthesis by preventing thymidine production, causing death of rapidly replicating cells.
C) This medication is a platinum-based antineoplastic agent that binds to DNA and RNA, miscoding information and/or inhibiting DNA replication, causing cell death.
D) This medication is an antiangiogenesis agent that reduces blood flow to the tumor cells, depriving them of nutrients needed for replication.
