Final answer:
For a nursing home resident admitted with chronic diarrhea, Contact Precautions, including personal protective equipment and rigorous hand hygiene, should be used to prevent infection transmission.
Step-by-step explanation:
A nursing home resident admitted to the hospital for evaluation and treatment of chronic diarrhea should be placed on isolation precautions to prevent potential transmission of infection. Based on the information provided, the type of isolation precautions could include implementing Contact Precautions, which involve wearing personal protective equipment such as gloves and gowns, ensuring rigorous hand hygiene before and after patient contact, and the use of dedicated medical equipment. These measures are crucial especially if the diarrhea is being caused by infectious agents like Clostridium difficile, which is known for its ability to cause severe antibiotic-associated diarrhea and is a common nosocomial pathogen. The use of Contact Precautions would help to prevent the spread of organisms and protect other patients and healthcare staff within the facility, especially considering the patient's history of chronic diarrhea and their vulnerable status as a nursing home resident.
