Certified Clinical Medical Assistant Exam Practice Question

Correct Answer: D

Rationale: Transporting a microbiology specimen in a labeled culture medium ensures that the sample remains viable for accurate testing. This medium preserves the microorganisms and prevents contamination, which is crucial for reliable results.

Option A, wrapping the specimen in aluminum foil, is inappropriate as it does not provide the necessary environment for microbial survival. Option B, placing the specimen on a heat block, can alter the sample's integrity and viability, leading to inaccurate results. Option C, using a urine cup, is not suitable unless specifically designed for microbiological specimens, as it may not maintain the required conditions for proper analysis.
