1Anaphylaxis can be defined as:
- AA systemic hypersensitivity reaction that can cause multi-organ failure and is often an emergency.
- BA severe Type I hypersensitivity reaction.
- CAn immune response mediated almost exclusively by IgG and IgM.
- DThe inability to breathe due to swollen airways.
2Generally Type I hypersensitivity reactions require multiple exposures to an agent before occurring.
- AVerdadeiro
- BFalso
3Potentiation of mast cell degranulation is most often attributed to:
- ANot removing the inciting agent.
- BPatient stress.
- CHistamine release.
- DOrgan failure and an inability to compensate.
4Clinical signs that accompany anaphylaxis may include: (select all that apply)
- APruritis, wheals, or edema on the skin.
- BBronchodilation.
- CIncreased gastric motility.
- DHypertension.
5A localized anaphylactic reaction has the potential to progress to a systemic anaphylactic reaction.
- AVerdadeiro
- BFalso
6Which of the following is true?
- ADogs are more likely to present with dyspnea, collapse, and excessive mucous production as signs of anaphylaxis than are cats.
- BCats are more likely present with dyspnea, collapse, and excessive mucous production as signs of anaphylaxis than are dogs.
- CCats are more likely to present with cutaneous lesions as signs of anaphylaxis than are dogs.
- DMore than one of these answer choices is correct.
7Like anaphylactic reactions, anaphylactoid reactions require previous sensitization, but occur more frequently on the third or fourth exposure than on the second.
- AVerdadeiro
- BFalso
8The difference between localized and systemic anaphylaxis is:
- AThe immunoglobulins involved, as the skin creates a different type of immunoglobulin than does the blood.
- BWhere the exposure occurred, for example a bee sting in the skin versus ingesting an allergen.
- CLocalized anaphylaxis is characterized by histamine as a mediator of degranulation, whereas localized anaphylaxis relies on serotonin.
- DLocalized anaphylaxis tends to be restricted to one location (often the skin), whereas systemic anaphylaxis involves 2 or more organ systems.
9Why is epinephrine such a key player in the treatment of systemic anaphylaxis?
- AIt reduces mast cell degranulation.
- BIt increases heart rate, and the subsequent increased movement of blood through the system pulls fluid from the interstitial spaces and reduces edema.
- CIt promotes bronchoconstriction, allowing a patient to slow their breathing and take deeper breaths.
- DIt induces peripheral vasodilation, allowing for better tissue perfusion.
10Which of the following follows appropriate dosing protocol for epinephrine? Select all that apply.
- AContinuous rate infusion at 0.05 mg/kg/min
- BIntratracheal dose at 0.02-0.04 mg/kg, diluted.
- CIV dose at ~0.05-0.1 mL/10 lbs
11Dexmethasone:
- AIs an antihistamine that can be given either orally (1 mg/lb) or IM (1-2 mg/kg).
- BIs an anti-inflammatory that can be given IV (0.1-0.2 mg/kg).
- CIs the name of a complex anaphylactic treatment protocol that involves extensive analgesics, sedatives, antihistamines, and fluids.
- DIs much better at addressing hypotension than is epinephrine.
