The CBIC Certified Infection Control Exam Study Guide (6th edition) emphasizes that aseptic technique is essential when obtaining clinical specimens, including wound cultures, to ensure accurate results and prevent contamination. Using aseptic technique minimizes the introduction of skin flora or environmental microorganisms that could lead to false-positive cultures and inappropriate clinical management.

Correct wound culture collection includes cleansing the wound as indicated, using sterile equipment, and avoiding contact with surrounding skin or nonsterile surfaces. This approach ensures that organisms identified in the culture are representative of true pathogens rather than contaminants. Proper specimen collection is a foundational infection prevention practice and directly affects diagnostic accuracy, antimicrobial stewardship, and patient outcomes.

Option A is incorrect because wound specimens are typically transported promptly at room temperature; refrigeration is not routinely recommended and may compromise certain organisms. Option C is incorrect because specimen containers must be labeled with at least two patient identifiers (such as full name and medical record number), not initials alone, to meet patient safety standards. Option D is incorrect because specimens should be obtained before initiation of antibiotic therapy whenever possible, as antibiotics can suppress bacterial growth and lead to false-negative results.

For CIC® exam preparation, it is critical to recognize that aseptic technique during specimen collection is the key correct practice, ensuring reliable laboratory results and supporting effective infection prevention and control efforts.
