Final answer:
Dialysis patients with infectious diseases, those undergoing chemotherapy, and those with compromised immune systems should be dialyzed on dedicated machines in separate areas to prevent cross-contamination and protect vulnerable individuals.
Step-by-step explanation:
Patients who should be dialyzed in a separate area on a dedicated machine in the dialysis center include those with infectious diseases, individuals undergoing chemotherapy, and patients with compromised immune systems. These measures are important for infection control and to prevent the spread of disease between patients who are particularly vulnerable to infections. Having dedicated equipment and areas helps in managing and reducing the risk of cross-contamination. Moreover, in the context of individuals undergoing chemotherapy or those with compromised immune systems, separate dialysis areas can help protect these patients from being exposed to potential infections that could exacerbate their already delicate health condition.
