Healthcare Associated Infections (HAI) Practice Exam

Improving skin preparation is essential in minimizing surgical site infections (SSIs) because it directly impacts the microbial load at the surgical site. Proper skin antisepsis reduces the number of pathogens on the skin, which is crucial since many SSIs are caused by organisms that originate from the patient's own skin flora. Effective skin preparation typically involves using appropriate antiseptics, such as chlorhexidine or iodine-based solutions, and ensuring that the area is cleaned thoroughly before surgery. This practice significantly reduces the risk of infection by creating a cleaner surgical field, ultimately leading to better patient outcomes and reduced healthcare-associated infection rates.

In contrast, increasing OR traffic can actually elevate the risk of contamination and infection, as more individuals moving in and out may introduce additional pathogens. Using razors for hair removal is discouraged because it can cause micro-abrasions that may lead to higher infection rates; clippers or depilatory methods are preferred. Delaying antimicrobial prophylaxis is also counterproductive, as timely administration is crucial for maximizing the effectiveness of the drugs in preventing infections during surgery.
