Which of the following is NOT a method to prevent healthcare-associated infections (HAIs)?

Immune system enhancement is not typically considered a direct method to prevent healthcare-associated infections (HAIs). In a healthcare setting, preventing HAIs involves specific, actionable practices that reduce the risk of infection transmission. Proper hand hygiene, for example, is a fundamental practice that significantly lowers the chances of spreading pathogens from one patient to another or from healthcare workers to patients. Wearing a mask is effective in blocking respiratory droplets that can transmit infections, particularly in situations where airborne or droplet precautions are necessary. Using sterile techniques is critical during invasive procedures to ensure that pathogens cannot enter the body, thereby preventing HAIs.

While a strong immune system is beneficial for overall health and can help the body fight infections, it is not a specific or practical method employed in healthcare settings for infection control. Instead, the focus is on established protocols and measures that directly mitigate risk within healthcare environments.
