What does aseptic technique aim to prevent?

• A. dehydration by maintaining fluids
• B. incorrect blood typing
• C. infection by excluding all pathogens from unbroken sterile fields
• D. incorrect dosage calculations

Answer: (C)

Aseptic technique is about preventing infection by keeping a sterile field free from microorganisms. This means practices like proper hand hygiene, using sterile gloves and instruments, and arranging the work area so that nothing non-sterile touches the sterile surfaces. The goal is to minimize any chance that pathogens can enter a wound or a sterile space during procedures, thereby reducing infections such as surgical site infections or contamination of injections.

This focus on preventing infection by excluding pathogens from unbroken sterile fields is what sets aseptic technique apart. It isn’t about fluids balance, blood compatibility, or dosing accuracy—those are different areas of care. Dehydration management concerns fluids, incorrect blood typing relates to transfusion safety, and incorrect dosage calculations deal with pharmacology and patient dosing.
