Question

question 1 of 5
which statement best defines a bloodborne pathogen?
a bacterium or virus carried in human blood and body fluids
an allergen spread by airborne particles
a parasite that only affects animals
a harmless organism found in drinking water

Explanation:

To determine the best definition of a bloodborne pathogen, we analyze each option:

• Option 1: A bacterium or virus carried in human blood and body fluids. Bloodborne pathogens are microorganisms (like bacteria or viruses) that are transmitted through blood and other body fluids, so this matches the definition.
• Option 2: An allergen spread by airborne particles. Allergens spread by air are not bloodborne (they relate to airborne transmission, not blood/body fluids), so this is incorrect.
• Option 3: A parasite that only affects animals. Bloodborne pathogens can affect humans (e.g., HIV, Hepatitis B), and this option's focus on only animals is incorrect.
• Option 4: A harmless organism found in drinking water. Bloodborne pathogens are typically harmful and transmitted via blood/body fluids, not harmless or in drinking water.

Answer:

A. A bacterium or virus carried in human blood and body fluids
