Which preparation step is unnecessary for Sr-89 Chloride therapy?

• A. Blood work
• B. Patient isolation
• C. Discontinuation of pain medications
• D. Physical examination

Answer: (C)

In the context of Sr-89 Chloride therapy, discontinuation of pain medications is unnecessary because this treatment is intended for patients who are experiencing pain due to metastatic bone disease. Sr-89 functions by targeting and localizing in areas of bone where there is increased osteoblastic activity, effectively providing palliative relief from pain without needing to stop existing pain management therapies. Other steps, such as blood work, patient isolation, and physical examination, are critical to ensure the patient's safety and overall health prior to the procedure. Blood work is important to monitor kidney function and overall blood counts, patient isolation may be necessary to avoid unnecessary radiation exposure to others after administration of the radionuclide, and a physical examination helps ensure that the patient is fit for the procedure and to assess their current health status. Therefore, while the other preparations aim to optimize the treatment process and safety, discontinuing pain medications does not contribute to the efficacy or safety of Sr-89 therapy.
