Clinical Scenario: The county public health department is notified that an organism has been identified in a local lake, which is popular for water recreation and swimming.  Acanthamoeba is familiar to the public health officials as an amoeba that can cause a fatal brain disease in both normal and immunocompromised individuals. An RN is a member of the taskforce assigned to the development and dissemination of community education. The team prepares information for the public to be released to media outlets and posted at the lake.  At the lakeside, public health officials post signs warning the public to avoid swimming in the lake.

The patient’s parents question which antibiotic will be given to treat their daughter’s infection. You inform her that_________.

Larval development of helminths occurs in which host?

Clinical Scenario: An RN at an elementary school notices a second grade female scratching and pulling at her pants. The student complains that her buttocks itch.
