Before instilling colloidal P-32 Chromic Phosphate into the peritoneal cavity, what preparation must be done?

• A. Administering a pain reliever
• B. Introducing Tc-99 Sulfur Colloid into the cavity
• C. Conducting a full nuclear medicine assessment
• D. Performing abdominal imaging

Answer: (B)

Instilling colloidal P-32 Chromic Phosphate into the peritoneal cavity requires the introduction of Tc-99 Sulfur Colloid prior to the treatment. This preparation is essential because Tc-99 Sulfur Colloid serves as a radiopharmaceutical tracer that helps in imaging and quantifying the distribution of the colloid after instillation. By using Tc-99, the imaging can help assess the effectiveness of the P-32 treatment and its localization within the peritoneal cavity, ensuring proper administration and monitoring of the radiopharmaceutical. The other options do not represent necessary preparations before the instillation. While pain management might be important in overall patient comfort, it is not a specific prerequisite for the procedure itself. A full nuclear medicine assessment provides valuable information but is not specifically required prior to the instillation of P-32. Performing abdominal imaging alone, without the introduction of the Tc-99 Sulfur Colloid, does not facilitate the tracking and monitoring needed for effective treatment with colloidal P-32.
