Which step would most directly address a block-clamping related problem?

• A. An improperly clamped block
• B. Reembedding the tissue
• C. Allowing the slide to drain
• D. Moving to blade section

Answer: (A)

Block clamping directly affects the stability of the tissue during sectioning. When the block isn’t secured properly, it can move or slip, leading to poor ribbons, chatter, or uneven sections. The most direct way to address this issue is to fix the clamp and re-seat the block so it is securely held before continuing. Other steps don’t tackle the cause: reembedding resolves embedding problems, letting the slide drain is unrelated to cutting quality, and moving to blade section would proceed with an unstable block, likely making the problem worse.
