Final answer:
The CDC is responsible for monitoring the observance of standard precautions guidelines.
Step-by-step explanation:
The regulatory body responsible for monitoring the observance of standard precautions guidelines is the Centers for Disease Control and Prevention (CDC).
The CDC is the main national public health agency in the United States and is charged with protecting the public from disease and injury. One of the ways it carries out this mission is by overseeing the National Notifiable Disease Surveillance System (NNDSS), which monitors diseases of public health importance on a national scale.
The CDC receives reports on notifiable diseases from regions in the United States and its territories, and it is legally required for physicians to submit reports on cases of notifiable diseases.
