North Carolina CNA Written Practice Exam

Infections can spread through various pathways, making option B the most comprehensive and accurate answer. This option highlights three key methods of transmission: airborne microorganisms, contaminated surfaces, and personal contact.

Airborne microorganisms refer to pathogens that can be inhaled via the air, which is particularly relevant for diseases such as the flu or COVID-19. Contaminated surfaces, often referred to as fomites, can harbor viruses and bacteria, allowing them to be transmitted when a person touches the surface and then touches their face or mouth. Personal contact encompasses a wide range of interactions, such as physical touch, which can facilitate the spread of infections easily from one person to another.

Understanding that infections can spread through multiple vectors is crucial for implementing effective hygiene and infection control measures. This knowledge assists individuals and healthcare providers in taking appropriate precautions, such as regular handwashing, wearing masks, and ensuring clean environments to minimize the risk of spreading infections.
