Final answer:
A nurse developing a community emergency response plan should collaborate with the CDC, a governmental agency focused on public health and emergency response, making it an appropriate partner for such initiatives.
Step-by-step explanation:
When developing and coordinating an emergency response plan for a community, a nurse would most appropriately collaborate with governmental agencies that have a direct mandate for public health and emergency management. This includes governmental agencies like the Centers for Disease Control and Prevention (CDC), which is the main national public health agency in the United States. The CDC's responsibilities include protecting the public from disease and injury, which directly align with emergency response initatives.
Moreover, the CDC oversees the National Notifiable Disease Surveillance System (NNDSS) and works with regional, state, and territorial health departments, enhancing its suitability for collaboration in developing community emergency response plans.
