Certified Clinical Medical Assistant Exam Practice Question

Correct Answer: C

Rationale: A sharps container should be closed for disposal when it is three-fourths full to prevent overfilling, which can lead to accidental needle sticks and contamination. Option A, closing it when completely full, poses a risk of spillage during handling. Option B suggests closing it at the end of each workday, which may not align with the actual fill level, risking safety. Option D focuses on specific procedures but does not address ongoing use throughout the day, potentially leading to unsafe conditions if not monitored regularly.
