Approximately what percentage of Floseal may be wasted due to advance preparation?

• A. ~5%
• B. ~11%
• C. ~25%
• D. ~0%

Answer: (B)

When using Floseal, some material loss happens because the mixed slurry and the applicator can't be fully recovered once prepared. The combination begins to set once prepared, so you must use it within a short time and any leftover that remains on the syringe, applicator, or mixing surfaces is discarded. That practical inefficiency translates to about 11% waste with advance preparation, which is why this option is the best choice. Smaller wastage like ~0% is unrealistic due to transfer losses, and ~5% or ~25% don’t align with typical usage data.
