MICRO EXAM 5 PORTAGE LEARNING QUESTIONS WITH 100%
DETAILED ANSWERS ASSURED SUCCESS
True or False: Although TB must be inhaled and reside in the
lung in order to cause infection, TB can also spread to the
brain, spine, and kidneys
True
True or False: Directly ingesting clostridium or its associated
spores will not cause illness in adults
True
A 5-month-old child is given honey at breakfast and begins
showing symptoms consistent with botulism. Would the child's
illness be classified as foodborne, infant or wound botulism?
Infant. Although food (honey) is consumed, foodborne botulism
is derived from improperly canned, low acid foods under
anaerobic conditions. Such conditions were not described. No
puncture wounds or injuries were described, ruling out wound.
The child is suffering from infant botulism, as honey is a
potential carrier of clostridium. The intestinal track of young
children is still developing and clostridium is able to colonize
and produce the associated toxin.

, Identify the medical condition characterized by robust
carbohydrate fermentation under anaerobic conditions,
swelling of the infected areas and fever.
Gas gangrene. The key identifier here is the robust
carbohydrate fermentation, which manifests as intense gas
production and swelling—both trademark conditions of gas
gangrene.
You develop a fever, chills and pneumonia after recently
returning from a getaway weekend where you sat in a hot tub.
What bacterial disease would a doctor suspect is causing your
symptoms? Would the doctor suspect you contracted it from
another person?
Legionnaires. No—legionella cannot be spread simply by direct
contact between people. Legionella can only be transmitted
through droplets small enough to be breathed in.
True or False: Pneumonic plague is often characterized by
painfully swollen lymph nodes
False. Bubonic targets the lymph system
