Final answer:
To prevent the transmission of Clostridium difficile, contact precautions are necessary, which include strict hand hygiene and disinfection of contaminated items. Personal protective equipment like gloves and gowns should be used when coming in contact with contaminated surfaces.
Step-by-step explanation:
To prevent the transmission of Clostridium difficile (C. diff), the appropriate transmission-based precaution to include in teaching by a home care nurse is A. Contact precautions. C. diff is primarily spread through spores which can contaminate surfaces, and these spores can be transmitted via direct contact with these contaminated surfaces or objects. Therefore, strict hand hygiene practices and the disinfection of potentially contaminated items are critical in preventing its spread.
Contact precautions involve the use of personal protective equipment such as gloves and gowns whenever there is potential contact with contaminated surfaces or items. Moreover, any healthcare worker or person who enters the isolation area must adhere to these precautions to avoid the transmission of the infection.
Other key measures to prevent the spread of C. diff include using dedicated medical equipment for the infected individual, proper disposal of waste, cleaning and disinfecting the environment thoroughly, particularly rooms and surfaces the patient has had contact with, and ensuring that anyone who is caring for or visiting the infected individual practices excellent hand hygiene before and after contact.
