Presence of foreign bodies on objects such as dressings, water, food, needles, wounds, or a patient’s body is called

• A. Contamination
• B. Exposure
• C. Direct contact
• D. Indirect contact

Answer: (A)

Contamination means there are foreign materials or infectious substances present on surfaces, objects, or people. When dressings, water, food, needles, wounds, or a patient’s body carry foreign material, that state is contamination. This is different from exposure, which is the act of coming into contact with the contaminated material and potentially being affected by it. Direct contact would be touching the contaminant directly, while indirect contact involves an intermediate object transferring the contaminant. Recognizing contamination helps guide decontamination and precautions to prevent exposure.
