A nurse is caring for a child who is suspected to have Enterobius vermicularis (pinworms). Which of the following actions should the nurse take?

A. Test the stool for occult blood: Testing for occult blood in the stool is not relevant for diagnosing pinworms. B. Perform a tape test: The tape test involves applying transparent tape to the perianal area to collect pinworm eggs, which is the appropriate diagnostic method for Enterobius vermicularis. C. Initiate IV fluids: IV fluids are not indicated for the diagnosis or treatment of pinworms unless the child is severely dehydrated, which isn't suggested by the scenario. D. Collect stool specimens for culture: Stool culture is not used to diagnose pinworms; the tape test is more appropriate.
