Which infection-control principle is essential in field care?

• A. Sharps disposal only
• B. Standard precautions: hand hygiene, gloves, and PPE as appropriate
• C. Hand hygiene only
• D. Wearing a mask always

Answer: (B)

Standard precautions form the baseline for infection control in field care. They protect both the patient and you by using hygiene and barrier methods consistently. Hand hygiene before and after patient contact reduces the spread of microbes. Gloves provide a barrier when dealing with blood, body fluids, mucous membranes, or contaminated surfaces. PPE such as gowns, eye protection, and masks should be used as the situation requires to prevent exposure to splashes, sprays, or aerosols. In the field, you rarely know which infections are present, and resources can be limited, so this combined approach is essential. Focusing on a single measure, like hand hygiene alone, or relying on masks in all situations, leaves other transmission routes unaddressed. Therefore, the standard precautions approach—hand hygiene, gloves, and appropriate PPE—is the most comprehensive and essential in field care.
