Which of the following statements regarding anaphylactic shock is MOST correct?
A) Sensitized people will experience less severe reactions upon
subsequent exposure.
B) Each subsequent exposure following sensitization often produces
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. - CORRECT ANSWER✅✅B) Each subsequent exposure following sensitization often
produces a more severe reaction.
,What is most likely to cause cardiogenic shock?
A) Heart Attack

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.
B) changes in gastric motility may delay gastric emptying, which
increases the risk for vomiting.
C) medications older patients take for hypertension often cause an
unusually fast heart rate.
D) the older patient's central nervous system usually reacts more
briskly to compensate for shock. - CORRECT ANSWER✅✅B) changes in gastric motility may delay
gastric emptying, which
increases the risk for vomiting.
