Which is an essential infection-control measure in in-flight medical care to prevent cross-contamination?

• A. Appropriate use of PPE
• B. Sharing equipment without cleaning
• C. Not performing hand hygiene
• D. Avoiding isolation precautions

Answer: (A)

In-flight care hinges on creating a barrier between the caregiver and potential infectious material. Using personal protective equipment properly provides that direct barrier, protecting both the patient and the crew from exposure to pathogens carried by bodily fluids, droplets, or aerosols. Gloves, masks, eye protection, and gowns are chosen based on the level of contact and risk, and the right donning and doffing technique is essential to prevent transferring contaminants to yourself or to others after care is complete. In the tight cabin environment, PPE offers immediate protection when space and resources for full cleaning aren’t always available, helping to limit cross-contamination as you assess and treat a patient.

Sharing equipment without cleaning would quickly spread pathogens between people, not performing hand hygiene undermines every protective step, and avoiding isolation precautions would let contagious material move through the cabin. PPE directly reduces these risks by creating a first line of defense during patient contact.
