Final answer:
Reverse isolation precautions are employed to protect immunocompromised patients from sources of infection, involving stringent hygiene and disinfection practices as part of aseptic techniques.
Step-by-step explanation:
The method of infection control used for immunocompromised patients, such as those receiving chemotherapy or immunosuppressant medications, is reverse isolation precautions. These precautions are specifically designed to protect vulnerable patients from being infected by others, as their compromised immune systems make them prone to opportunistic infections. Reverse isolation involves separating the immunocompromised patient from potential sources of infection, practicing stringent hand hygiene, and careful disinfection of all items entering the patient's environment. It is part of a broader set of protocols known as aseptic technique, which is essential in preventing contamination during medical procedures, thereby reducing the risk of sepsis and maintaining a sterile field.
