Which statement about barrier technique is true?

• A. They protect clinicians from infection only
• B. They have no effect on cleaning
• C. They must be used only if surfaces are cleaned
• D. They prevent cross-contamination and reduce disinfectant use between patients

Answer: (D)

Barrier technique uses disposable protective barriers to create a physical layer between the patient, the clinician, and the operatory environment. This includes gloves, masks, eye protection, gowns, and barrier covers for surfaces and equipment. The goal is to prevent microorganisms from moving between patients and surfaces, thereby stopping cross-contamination. Because these barriers are placed for each patient and disposed of afterward, many surfaces stay protected and don’t require full disinfection between patients, which helps reduce the amount of disinfectant used. At the same time, proper barrier use is part of standard precautions for everyone’s safety, not just clinician protection. It’s not limited to surfaces being cleaned, and barriers do not eliminate the need for cleaning and disinfection of non-covered areas or reusable instruments. The key idea is that barriers help prevent transmission and streamline cleaning needs across patients, making the statement that barrier technique prevents cross-contamination and reduces disinfectant use between patients the best fit.
