Final answer:
Contact precautions are mandatory in a hospital setting for patients with Hepatitis B, measles, meningitis, and infectious diarrhea due to the contagious nature of these diseases.
Step-by-step explanation:
Contact precautions are critical in a hospital setting, especially for patients diagnosed with contagious diseases that pose high risks of transmission. In context, these precautions would be mandatory for all the listed conditions: Hepatitis B, measles, meningitis, and infectious diarrhea.
For example, Hepatitis B can spread through contact with infected blood, therefore special protocols should be in place to limit this risk of transmission, such as personal protective equipment and stringent hand hygiene.
On the other hand, infectious diseases like measles and meningitis can be spread from person to person through close contact making quarantine necessary.
Lastly, conditions like infectious diarrhea, which can result from exposure to bacteria such as C. difficile, necessitate contact precautions due to the possibility of bacterial spread.
