3. Which of the following statements regarding anaphylactic shock is MOST
   correct?
   A) Sensitized people will experience less severe reactions upon
   subsequent exposure.

   a more severe reaction.
   C) Anaphylactic shock is the result of immune system failure due to a
   toxic exposure.
   D) Anaphylactic shock occurs immediately after a person is sensitized
   to an allergen. ANS: B Each subsequent exposure following sensitization

5. When treating an 80-year-old patient who is in shock, it is important to
   remember that:
   A) compensation from the respiratory system usually manifests with
   increased tidal volume.

unusually fast heart rate.
D) the older patient’s central nervous system usually reacts more
briskly to compensate for shock. ANS: B changes in gastric motility may delay
gastricemptying, which
increases the risk for vomiting.
