Chapter 18 Immunologic Emergencies

  1. Prolonged respiratory difficulty can cause ____, shock, and even death.
  2. In dealing with allergy-related emergencies, you must be aware of the possibility of acute ____ ____ and cardiovascular collapse.
    airway obstruction
  3. At least ____ Americans per year die of allergic reactions.
  4. Allergy-related emergencies may involve (two things):
    • Acute airway obstruction
    • Cardiovascular collapse
  5. The two main chemicals involved in an allergic response include:
    • histamines
    • leukotrienes
  6. Wheezing is one of the most common signs of:
  7. A high-pitched, whistling breath sound that is typically heard on expiration.
  8. Results from bronchospasm/bronchoconstriction and increased mucus production.
  9. Consists of small areas of generalized itching or burning that appear as multiple, small, raised areas on the skin.
  10. In anaphylaxis, you may also note ____ as a result of hypovolemic shock due to increased capillary permeability.
  11. The five most common allergens:
    • Insect bites and stings
    • Medications
    • Plants
    • Food
    • Chemicals
  12. A person will typically experience an allergic reaction after becoming ____ by the first exposure.
  13. Death from stinging insects far outnumber deaths from ____.
  14. Raised, swollen, well-defined area on the skin.
  15. The stinger of the honeybee can continue to inject venom for up to __ minutes after the bee has flown away.
  16. About _% of people may have anaphylactic reactions from stings.
  17. This type of allergy accounts for about 200 deaths per year and can cause anaphylaxis.
  18. More than two thirds of patients who die of anaphylaxis do so within the first:
    half hour
  19. ____, a harsh, high-pitched inspiratory sound, occurs when swelling in the upper airway closes off the airway; the swelling can eventually lead to total obstruction.
  20. ____ occurs because of narrowing of the air passages, which is mainly the result of contraction of muscles around the bronchioles in reaction to the allergen.
  21. Prolonged respiratory difficulty can cause a rapid heartbeat (____), shock, and even death.
  22. In a patient experiencing an allergic reaction, ____ ____ is a useful method that you can use to assess the patient’s perfusion status.
    pulse oximetry
  23. Epinephrine is a ____; it mimics the sympathetic (fight-or-flight) response.
  24. Most patients who die of anaphylaxis do so within the first __________ following exposure.
    A. 90 minutes
    B. 30 minutes
    C. 60 minutes
    D. 5 minutes
    B. 30 minutes
  25. Injection of medications such as penicillin may cause an immediate and severe reaction. "Immediate" is described as:
    within 30 minutes.
  26. Eating certain foods, such as shell fish or nuts, may result in a relatively slow reaction that still can be quite severe. That relatively slow reaction time is:
    more than 30 minutes.
  27. Epinephrine can have an effect within:
    1 minute.
