Questions: A resident on transmission based precautions must be * Placed in a private/single room if available/appropriate In a shared room with a cohort with same pathogen Or in shared room with cohort with limited risk factors All of the above are appropriate

The answer is the last one: All of the above are appropriate.

Explanation for each option:

1. Placed in a private/single room if available/appropriate: This is correct because placing a resident in a private room can help prevent the spread of infection to others, especially if the pathogen is highly contagious or if the resident is unable to follow infection control measures.

2. In a shared room with a cohort with the same pathogen: This is also correct. Cohorting residents with the same pathogen can be an effective way to manage space and resources while minimizing the risk of spreading the infection to those who are not infected.

3. Or in a shared room with a cohort with limited risk factors: This option is appropriate in certain situations where the risk of transmission is low, and the residents have limited risk factors for severe disease or complications.

In summary, all of the options provided are appropriate strategies for placing a resident on transmission-based precautions, depending on the specific circumstances and resources available.
