Certified Clinical Medical Assistant Exam Practice Question

Correct Answer: C

Rationale: Opening hinged instruments during sanitization is essential to effectively remove any contaminants trapped in the hinges (C). This ensures thorough cleaning and reduces the risk of infection.

Option A, preventing erosion of hinges, is not the primary purpose of this action; rather, it focuses on cleaning. Option B, preventing cutting edges from becoming dull, is unrelated to the sanitization process, as dullness is affected by usage rather than cleaning. Option D, removing mineral deposits, is also not the main goal; while it may occur, the focus is on eliminating biological contaminants.
