Answer to Question 1

B, C, D
Children are particularly vulnerable to environmental toxins because they take in larger doses, pound-for-pound, of toxins than adults, their organ systems are less able to remove the toxins than those of adults, and they have a greater number of years of life expectancy over which to develop complications from the toxic exposure.

Answer to Question 2

A, B, D
You should suspect a biological event when large numbers of ill persons present who have unexplained yet similar symptoms; when unexplained deaths occur, particularly among young and healthy populations; when an unusual pattern (e.g., geographical, season, patient population) is associated with the symptoms; when the patient fails to respond to traditional therapy; and when a single patient presents with symptoms suggestive of an uncommon agent (e.g., anthrax, smallpox). Once you suspect a biological event, notify incident command immediately.
