The nurse is developing a plan of care for marrow suppression, the major dose-limiting adverse reaction to floxuridine (FUDR). How long after drug administration does bone marrow suppression become noticeable?

  • A. 24 hours
  • B. 7 to 14 days
  • C. 2 to 4 days
  • D. 21 to 28 days
Correct Answer: B

Rationale: The correct answer is B: 7 to 14 days. Marrow suppression from floxuridine typically occurs 1-2 weeks after administration due to its effects on rapidly dividing cells in the bone marrow. This is known as the nadir period. Choices A, C, and D are incorrect because 24 hours is too soon for noticeable effects, 2 to 4 days is too short for the nadir period, and 21 to 28 days is too long for the onset of marrow suppression. The correct choice aligns with the expected timeframe for floxuridine's impact on bone marrow function.
